THE EFFECTS OF WORKPLACE OSTRACISM & WORKPLACE INCIVILITY ON EMPLOYEES’ TURNOVER INTENTION. THE MEDIATING ROLE OF KNOWLEDGE HIDING. ABSTRACT The primary aim of this investigation is to explore the interplay among workplace ostracism, workplace incivility, and turnover intention, taking into account the mediating influence of knowledge hiding behavior, which encompasses evasive hiding, playing dumb, and rationalized hiding. Data for the study were gathered through structured questionnaires distributed to a sample of employees (referred to as participants) in small to medium-sized enterprises located in HCMC. Employing structured equation modeling as the analytical approach, the study underscores noteworthy findings, indicating a positive impact of both workplace ostracism and workplace incivility on employees' turnover intention. Notably, knowledge hiding behavior emerges as a significant mediator in the association between workplace ostracism, workplace incivility, and employees' turnover intention. The study emphasizes the necessity of scrutinizing individual personality dispositions to comprehend the intricate relationships among variables like workplace ostracism, workplace incivility, and knowledge hiding behavior. Mitigating inappropriate employee behavior is advocated through initiatives such as realistic job previews and the establishment of exemplary conduct. This research makes a substantial contribution to the existing literature on knowledge hiding behavior, offering valuable insights into the organizational and individual factors influencing such behavior. Remarkably, this study represents a pioneering effort in examining the predictive influence of the specified variables.

Research background and statement of the problem To gain a competitive edge in the economy, knowledge is recognized as a valuable asset (Singh, 2019). Knowledge sharing not only enhances organizational performance and innovation capabilities but also reduces costs. Companies initiate various strategies such as implementing software for knowledge sharing, introducing incentive systems, nurturing enduring connections with employees over an extended period, and creating a conducive atmosphere that promotes the exchange of knowledge among employees. Despite these efforts, employee knowledge sharing remains suboptimal, with deliberate concealment of information from colleagues being prevalent (Xiao & Cooke, 2019). Scholars emphasize the significance of effective knowledge sharing for organizational success, considering it pivotal for facilitating innovation and enhancing performance, particularly within production-oriented companies.. The term "knowledge hiding" has emerged as employees deliberately choose not to share information, as indicated by Han et al. (2021). This intentional concealment or withholding of requested information is considered a detrimental factor impacting organizational performance, although there is a scarcity of comprehensive studies investigating its root causes. (Kumar & Varkkey, 2018). Despite the widespread emphasis on knowledge sharing, the concept of knowledge concealment is equally important but often overlooked. The intentional withholding of information distinguishes knowledge hiding from the absence of sharing information. Understanding employees' motivations at work is crucial for fostering knowledge transfer and sharing within organizations. Irum et al.'s study highlights the importance of mutual understanding and reciprocity in explaining members' negative responses to mistreatment in the workplace (Anand & Hassan, 2019). Workplace ostracism (WO) and workplace incivility (WI) are critical factors influencing social exchange behaviors. WO introduces stressful, emotionally draining, physically and mentally exhausting behaviors, leading to less productivity. The ongoing study investigates the ramifications of workplace discourtesy on the efficiency of work and the contributions made by employees. The widespread prevalence of workplace incivility and ostracism can have detrimental effects on an organization's overall performance and employee engagement. This pervasive issue obstructs constructive behaviors while fostering counterproductive work behavior (CWB). (Zhao et al.). Workplace incivility and ostracism may contribute to turnover intention as a predictor linked to knowledge hiding. Research findings indicate that WI and WO can result in knowledge concealment among employees, adversely impacting organizational performance and stakeholders. Researchers are actively investigating the effects of WI and WO, exploring their associations with job anxiety and the propensity to hide information. Many workers experiencing WI and WO keep their concerns due to fear of discrimination (Nguyen et al., 2022), resulting in decreased productivity, weakened work motivation, and diminished loyalty to the organization. 1.2. Research objectives ● Firstly, this paper analyzes and evaluates the impact of WI and TI. ● Secondly, to analyze and evaluate the impact of WO and TI. ● Thirdly, to analyze the mediating role of Knowledge Hiding in the correlation between WI and TI as well as WO and TI. ● Finally, it also proposes managerial implications to solve knowledge concealment problems at work for managers. 1.3. Research question: ● How does Workplace Ostracism influence the extent of Knowledge Hiding? ● In what manner does Workplace Incivility dictate the occurrence of Knowledge Hiding? ● Are there interconnected relationships between Knowledge Hiding behaviors and Workplace Incivility, Workplace Ostracism, and Turnover Intention? 1.4. Research scope 1.4.1. Content Scope This study primarily measures the effects of workplace ostracism, workplace incivility on turnover intentions. The study also examines and assesses the mediating role of Knowledge Hiding on employee’s TI at work. 1.4.2. Location Scope The scope of the research is Ho Chi Minh City, where several Vietnamese provinces send workers there as well as foreigners. 1.4.3. Time Scope The research was carried out from January 2024 to April 2024. 1.4.4. Research method Quantitative research techniques are used in this study. The research gap was identified by reviewing previously published papers and proposing a new theoretical research model to investigate in this paper. In addition, a Google Form questionnaire is used to collect data for this study's convenient sample collection approach. After that, we use PLS-SEM to analyze the data and test the scale and model. 1.4.5. Target population Since the research object of the author's group is Turnover Intention, employees who work for small and medium-sized businesses are the survey subjects that our group is focusing on. 1.5. Research contribution This research contributes to the enhancement of our understanding of the impact of workplace incivility and workplace ostracism on negative outcomes. It enriches the literature on turnover intentions and Knowledge Hiding by providing diverse perspectives, integrating these negative outcomes with the phenomena of workplace incivility and workplace ostracism. 1.6.

The proposed research model and hypotheses are also introduced in this chapter. Chapter 3: The research process and methodology employed in this study are discussed in this chapter. Also, it describes the use of questionnaires, measuring scales, sampling methods, and the methods of collecting and analyzing data. Chapter 4: The results from PLS-SEM analysis are presented in this chapter. Chapter 5: This chapter contains research conclusions, limitations, and suggestions for further research. CHAPTER 02: LITERATURE REVIEW AND HYPOTHESIS DEVELOPMENT 2.1. Definitions 2.1.1. Workplace Ostracism. Employees experience decreased engagement and disconnection when subjected to workplace ostracism, leading to dissatisfaction and a sense of being outsiders within their work environment. The occurrence of workplace ostracism results in unproductive work behavior (Issac et al., 2019), contributing to reduced efficiency within organizations. This problem manifests in less productive behavior, causing physical, mental, and emotional exhaustion, as well as psychological and physical harm. The impact of workplace ostracism extends to job anxiety and innovation-related challenges at work (Riaz et al., 2019; Naseem et al., 2020). A growing number of organizations are focusing on issues related to social exclusion, mistreatment, and workplace ostracism, recognizing the significant negative consequences at both individual and organizational levels (Gulek, 2020). Workplace ostracism is characterized by a feeling of being overlooked at work, posing threats to self-esteem, belonging, control, and a sense of meaning in one's life. Studies on workplace ostracism reveal that any part of the workplace, including supervisors, coworkers, or external clients, can contribute to the ostracizing experience (Zhao et al., 2017). Perceptions of workplace ostracism are subjective, leading affected coworkers to exhibit hostile behaviors toward their colleagues, with manifestations varying in subtle and overt expression depending on the situation (Aljawarneh & Atan, 2018). In addition to affecting an individual's ability to embrace and sustain healthy habits, these outcomes result in diminished workplace motivation, reduced participation in civic activities, and a range of health issues. Researchers have turned their attention to the efficacy of organizations, unveiling instances of deviant behavior among colleagues, incompetence, and counterproductive actions stemming from heightened social interactions. Similar trends manifest across a spectrum of organizations, as evidenced by Howard et al.'s findings in 2020. 2.1.2. Workplace Incivility Liu et al. (2019) define workplace incivility as a behavior characterized by disrespect towards others, leading to a sense of disconnection, disrupted interpersonal relations, and underdeveloped empathy. Research on workplace incivility has explored incidents involving individual workers, such as checking emails and using mobile devices to send text messages within meeting sessions, as well as making disrespectful comments or uttering derogatory remarks (Wang & Chen, 2020). Scholars have increasingly focused on these once-disregarded incidents for two primary reasons. Firstly, ignoring the costs associated with WI is deemed irresponsible (Armstrong, 2018). Researchers assert that the repercussions of WI extend to both organizations and individuals, exerting adverse effects on them, negatively influencing the welfare of employees, their TI, and their dedication to their roles, as indicated by previous studies. Secondly, workplace incivility has global implications. Despite numerous studies conducted in American contexts, Liu et al. illustrate that workplace incivility is prevalent in Asian work environments, positively affecting both the company and personnel. However, limited empirical research has explored the consequences arising from WI within the Asian professional landscape. (Shi et al., 2018). Pearson and Andersson (1999) conducted a foundational study on workplace incivility, defining it as an employee's conduct within the professional environment. Described as "low-level divergent behavior with ambiguous intent to harm, breaching workplace norms for mutual respect" (Andersson & Pearson, 1999, p. 455), incivility is characterized by verbal rather than physical actions, indirect rather than direct expressions, and passive rather than active behaviors, as scrutinized by Neuman and Baron (1996). Subsequent research expands the definition to encompass activities such as gossiping and privacy invasion (Martin & Hine, 2005). Incivility is also depicted as the daily botherations of individuals, turning unpleasant and stressful with repetition (Grandey & Kern, 2009, p. 47). In contrast to more severe behaviors like aggression, sabotage, and harassment, Lim et al. (2008) propose that incivility can be viewed as a milder form of divergent actions, where the intention of wrongdoing is merely perceived. 2.1.3. Knowledge Hiding The occurrence of knowledge hiding, characterized by the intentional withholding or concealment of requested knowledge by an individual, holds extensive implications for both organizations and interpersonal relationships within them (Connelly et al., 2012). In-depth research has shed light on diverse consequences of knowledge hiding, including its adverse effects on creativity (M. Cerne et al., 2014), innovative work behaviors, and individual performance (M. Cerne et al., 2017). Furthermore, knowledge hiding has been linked to the emergence of interpersonal distrust (Connelly et al., 2012) and strained relationships among individuals (Connelly et al., 2015). Notably, evidence suggests that the practice of knowledge concealment can rapidly spread, permeating from supervisors to subordinates (Arain, Bhatti et al., 2018). When employees actively partake in the sharing of both implicit and explicit knowledge with their colleagues, it markedly enhances an organization's overall effectiveness, creativity, and proficiency (Lin, 2015). Despite the intentional nature associated with knowledge concealment, there are instances where employees may choose to keep certain information to themselves (Connelly et al., 2012). This knowledge encompasses task-specific details or expertise related to a job (e.g., Bartol & Srivastava, 2002). The conscious decision not to share knowledge underscores the distinction between hoarding and hiding (Zhao & Xia, 2017), resulting in significant implications for knowledge sharing and organizational performance. Nonetheless, as noted by Connelly et al., this concept diverges from Counterproductive Work Behaviors (CWBs), given that knowledge hiding does not necessarily aim to inflict harm on others or the organization, unlike CWBs that involve intentional acts of harm. Nevertheless, knowledge hiding may harbor positive intentions at times. For instance, justified hiding may aim to protect others' feelings or maintain confidentiality (e.g., abstaining from sharing specific confidential documents). Knowledge hiding is a dyadic phenomenon and should not be universally characterized as negative behavior, unlike CWBs, which are explicitly designed to harm organizations or stakeholders. 2.1.3.1. Evasive Hiding In the act of concealing knowledge, employees employ three distinct strategies, with the selection of a particular strategy contingent on the nature of the knowledge inquiry (Connelly et al., 2012). When faced with intricate knowledge queries, employees are inclined to employ strategic concealment. As delineated by Connelly et al. (2015), strategic concealment transpires when "the individual offering misleading or incorrect information makes a deceptive commitment to providing a comprehensive answer at a later time." This strategy involves an element of deception, even though the employee harbors no intention of furnishing the information. 2.1.3.2. Playing Dumb The second approach can be characterized as "pretending to be unaware of the sought-after knowledge" (Von der Trenck, 2019). In this scenario, an employee assumes a guise of not possessing the knowledge that is being sought. 2.1.3.3. Rationalized Hiding The third tactic is termed as rationalized hiding, wherein individuals "provide a rationale by presenting reasons or assigning blame to others." This approach is employed when dealing with confidential information or aiming to safeguard the emotions of colleagues. Despite an individual's perception of positive intentions behind knowledge hiding, it has adverse effects on organizational performance, collaboration, and advancement (Peng, 2013). Nevertheless, the factor of individual willingness to withhold knowledge remains insufficiently examined. Instances of such concealment persist, notwithstanding organizational initiatives geared towards promoting knowledge sharing (Webster et al., 2008). 2.1.4. Turnover Intention The inclination of employees to part ways with an organization is termed as "turnover intentions." It is a critical factor that exerts an impact on employee productivity. Chad and Sut (2011) emphasized that the turnover of employees leads to economic losses, significantly diminishing job performance. According to Barak et al. (2001), employee turnover is considered hazardous and costly, disrupting organizational effectiveness and employee productivity to a considerable extent. Administrators are compelled to invest significant resources and efforts in acquiring new talent to offset the loss incurred by departing individuals. Bonett and Wright's (2007) study delineated two categories of employee turnover: voluntary and involuntary. Voluntary turnover occurs when employees intentionally leave the organization for various reasons, often driven by the prospect of better opportunities, whether spiritual or mental. This departure can have a detrimental impact on the organization. Involuntary turnover, on the other hand, is instigated by factors such as poor performance, layoffs, or other reasons that harm the organization's interests. Previous research contends that turnover intention is a gradual process encompassing thoughts of leaving a job, searching for a new one, or deciding whether to stay or leave (Mobley, 1982; Milton and Jacqueline, 2007; Khan, Imran, & Nisar, 2016). Ultimately, employee turnover can be defined as an individual's anticipated likelihood of permanently leaving the organization in the near future (Miriam and Matthias, 2011). 2.2. Theoretical backgrounds 2.2.1. COR Theory Hobfoll developed a new theory in 1989 called the Conservation Of Resources theory. The model's basic tenet is that people strive to retain, protect, and build resources and that what is threatening to them is the potential or actual loss of these valued resources. According to Hobfoll's COR theory (1989), people are driven to acquire resources, which motivates them to invest in order to improve their status, love, assets, or self-esteem, depending on their goals and the direction of their investment. Psychological stress happens when an individual's resources are in danger or they could lose a large number of their belongings. The threat to human resources comes from a growth in the amount of work completed in a certain length of time (Work Overload), which pushes people to spend resources on work that could be utilized for other things. Due to the lack of resources, this prevents them from completing other objectives, which results in stress. When a person's sense of belonging is threatened, Hobfoll (1989) asserted that the loss of resources is what causes depression and other serious unpleasant emotions like stress to emerge. Ostracized employees view their social resources, which are valuable resources utilized as auxiliary tools for problem-solving and dealing with difficult situations at work, as being threatened in the setting of Workplace Ostracism (Greenhaus & Powell, 2006). Employees may get focused on work-related issues due to a lack of social resources, which could result in Job Stress. 2.2.2. Role Theory In a particular status, certain standardized behavioral patterns are considered to be in the role. In other words, a status has a role that needs to be fulfilled in accordance with the laws that apply. According to Role Theory, individuals will suffer role Ambiguity when they lack the knowledge necessary to perform specific roles effectively. When a person or group exercises their rights and obligations and then fulfills their role (Makom, 2021). People perform poorly at work when they feel that the workload is excessive for the job they are doing. This results from their lack of clarity around their role. This is comparable to Workplace Conflict, where employees' ideas may be disregarded if their roles are not clearly defined, leading to bad performance. The same thing occurs when there is work-related stress due to the inappropriate role, which results in subpar performance. 2.2.3. Social Exchange Theory The theory of Social Exchange helps to explain how people behave (Cropanzano & Mitchell, 2005). Social Exchange Theory is present in workplace relations. The law of reciprocity, which states that when people are properly needed by others, they will feel obligated to repay them with good treatment, is the main tenet of social exchange theory, which also examines how well superiors and subordinates interact and how organizations support their employees. A business leader who is aware of what the workforce wants and who can articulate the benefits of meeting those expectations will make every effort to perform at their highest level. 2.3. Prior relevant studies 2.3.1. Muhammad Mohsin & Khalid Jamil et al., 2022 Elongating Nexus Between Workplace Factors and Knowledge Hiding Behavior: Mediating Role of Job Anxiety This research aims to explore the connection between workplace ostracism, workplace incivility, and knowledge hiding behavior (evasive hiding, playing dumb, rationalized hiding), taking into account the mediating role of job anxiety. The data for this study were gathered through structured questionnaires administered to 275 participants (i.e., employees) employed in small to medium-sized enterprises across five major cities in Pakistan. Structural equation modeling was employed as the analytical technique for the collected data. Notably, the study findings indicate a positive impact of workplace ostracism and workplace incivility on employees' knowledge hiding behavior, with job anxiety significantly mediating the relationship between workplace ostracism, workplace incivility, and knowledge hiding behavior. This study underscores the importance of exploring individual dispositions to comprehend the interplay between variables such as workplace ostracism, workplace incivility, and knowledge hiding behavior. The implementation of a campaign for a realistic job preview, coupled with setting exemplary standards, has effectively curbed employees' inappropriate behavior. Furthermore, the study makes a substantial contribution to existing literature on knowledge hiding behavior by offering valuable insights into organizational and individual factors that subsequently shape individuals' knowledge hiding behavior. This study stands out as the first of its kind to delve into the predictive implications of the specified variables. 2.3.2. Zainab Mahfooz et al., 2017 Does Workplace Incivility & Workplace Ostracism influence the Employees’ Turnover Intentions? Mediating Role of Burnout and Job Stress & Moderating Role of psychological Capital The primary objective of this study is to scrutinize the pivotal role of workplace incivility and ostracism in employees' turnover intentions, focusing on the mediating impact of burnout and job stress, along with the moderating influence of psychological capital in the health sector. The study adopts a descriptive, quantitative, and longitudinal approach. Data collection occurred at two different time points, employing simple random sampling techniques. Questionnaires were distributed among employees and doctors in various hospitals, with only 200 out of 300 questionnaires deemed reliable. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) techniques were utilized to investigate the behaviors under study. The findings uncovered significant and negative relationships between workplace incivility, workplace ostracism, and turnover intentions. Furthermore, burnout was identified as a significant and partial mediator in the relationship between workplace incivility and turnover intentions. Similarly, the results illuminated that job stress also partially mediates the association between workplace ostracism and turnover intentions. Additionally, psychological capital was found to significantly moderate the relationships among workplace ostracism, job stress, and turnover intentions. This study provides valuable insights into the adverse repercussions of psychological behaviors within organizations. 2.3.3. Lalatendu Kesari Jena & Deepika Swain, 2021 How Knowledge-Hiding Behavior Among Manufacturing Professionals Influences Functional Interdependence and Turnover Intention Our study involved 363 executives employed across three public and two private manufacturing organizations in eastern India. A t-test was conducted to analyze the differences in the study variables. The statistical findings indicated no significant difference among the study variables, suggesting that, despite varying levels of management, there was no notable distinction in perceiving workplace incivility, knowledge-hiding behavior, and items related to Functional Interdependence (FI) and Turnover Intention (TI) in our instruments. Correlation findings revealed a negative association between workplace incivility and functional interdependence (r = −0.37, p < 0.01) and a positive association between workplace incivility and turnover intention (r = 0.32, p < 0.01). The combined effect of workplace incivility (β = −0.59, p < 0.001) and the significant presence of knowledge-hiding behavior (β = −0.68, p < 0.01) when the dependent variable is FI suggests that knowledge-hiding behavior partially mediates the association between workplace incivility and FI. Similarly, the impact of workplace incivility (β = 0.43, p < 0.01) diminishes when the influence of knowledge-hiding behavior (β = 0.66, p < 0.001) is substantial, with TI as the dependent variable. The inverse relationship between knowledge hiding and FI, coupled with the direct relation between sharing and TI, highlights the intricate dynamics. An exhaustive data sample and rigorous statistical analysis are essential to elucidate the precise impact of TI and FI due to the presence or absence of knowledge sharing and hiding. 2.3.4. Sidra Riaz, Yusen Xu and Shahid Hussain, 2019 Workplace Ostracism and Knowledge Hiding: The Mediating Role of Job Tension This investigation delved into the repercussions of workplace incivility on employees' inclination to conceal knowledge. Grounded in the conservation of resource theory, the study aimed to pinpoint the influence of job tension as an intermediary and the moderating impact of employee allegiance. Employing a time-lagged research framework, information was gathered from 392 individuals in the textile industry. The findings reveal a positive correlation between workplace incivility and knowledge hiding behaviors like evasive hiding and playing dumb, although no significant association was found with rationalized hiding. Specifically, workplace incivility heightens job tension, and this tension serves as a mediator between workplace incivility and knowledge hiding. Furthermore, it was observed that workplace incivility undermines the advantages of employee loyalty, with high levels of workplace incivility exerting a more pronounced effect on job tension. The study also delves into the theoretical and practical implications of these findings. 2.3.5. Lata Bajpai Singh & Shalini Srivastava, 2021 Linking workplace ostracism to turnover intention: A moderated mediation approach This research aims to investigate the impact of workplace ostracism on the relationship between turnover intention and the moderating and mediating roles of variables. Data were collected from 350 employees in hotels located in the Delhi NCR region of India. Structural Equation Modeling and Macro PROCESS (Hayes, 2013) were employed to analyze the proposed relationships. Openness to experience and neuroticism were identified as partial mediators in the influence of workplace ostracism on turnover intention, and the mediating effects were moderated by resilience. These findings contribute to understanding how resilience can modify the link between workplace ostracism and turnover intention. Notably, this study, the first of its kind in the Indian context, connects variables such as workplace ostracism, turnover intention, and personality traits to elucidate their impact on the hotel industry. Grounded in the 'Conservation of Resource' perspective, the research introduces a novel dimension to the existing knowledge framework. 2.3.6. Elham Anasori et al., 2021 The mediating role of psychological distress between ostracism, work engagement, and turnover intentions: An analysis in the Cypriot hospitality context. Utilizing the frameworks of the conservation of resources and job-demands resource theories, this investigation puts forth and validates psychological distress as an underlying mechanism that mediates the connections between workplace ostracism, work engagement, and turnover intentions. Additionally, it explores how resilience and perceived external employability influence the aforementioned associations. The data for this study were sourced from full-time employees in four- and five-star hotels. The results indicate that psychological distress acts as a mediator in the link between workplace ostracism and turnover intention, but does not play a mediating role in the relationship between workplace ostracism and work engagement. Interestingly, workplace ostracism diminishes the work engagement of less resilient employees while unexpectedly heightening that of more resilient employees. Contrary to expectations, the findings did not support the notion that employees with perceived high external employability would exhibit stronger turnover intentions compared to those with lower external employability. This research provides novel insights into the interplay of workplace ostracism, engagement, and turnover intention, and discusses pertinent theoretical implications and managerial considerations. 2.4. Research framework and hypothesis development 2.4.1. Research framework Source: Author’s own 2.4.2. Hypothesis development 2.4.2.1. Workplace Ostracism and Knowledge Hiding The COR theory posits that individuals possess resources to fulfill their needs, and as a result, they strive to acquire and maintain valuable resources to reduce the risk of losing support from both others and the environment (physical, social, cognitive). Rooted in the COR theory, this perspective elucidates how workplace ostracism depletes individuals' crucial resources essential in the work environment (Samma et al., 2020). In response to such situations, individuals may activate protective mechanisms, leading to continuous stress as a consequence of ongoing resource depletion, ultimately resulting in negative outcomes (Sepahvand & Mofrad, 2021). The influence of workplace ostracism on concealing knowledge and emotions during the workday, as anticipated by the COR theory, has been demonstrated. Instances of hiding valuable information are more likely to occur when employees are unaware that they might face consequences for withholding sensitive data. Hence, the awareness of when to conceal and when not to conceal can have significant ramifications. Hence, we proposed the following hypotheses: H1: Workplace ostracism positively influences evasive hiding. H2: Workplace ostracism positively influences playing dumb. H3: Workplace ostracism positively influences rationalized hiding. 2.4.2.2. Workplace Incivility and Knowledge Hiding Individuals within an organization engage in tasks that demand knowledge, expertise, and ideas. Knowledge hiding involves the intentional withholding or concealing of information when requested (Liu et al., 2019). Despite the expectation for employees to share information, various factors lead them to withhold it. Fear of losing power or status, dissatisfaction with colleagues, and a system emphasizing individual performance over collective outcomes contribute to this behavior (Wang & Chen, 2020). Employees employ different strategies for knowledge concealment, such as playing dumb when they already possess the answers, evasive hiding by offering knowledge but refusing to share, and rationalized hiding by providing reasons why information cannot be disclosed or blaming third parties (Armstrong, 2018). To enhance our understanding of reciprocity and social exchange in the workplace (Aljawarneh & Atan, 2018), the concept of reciprocation is implemented. Workplace incivility expressed from one party to another in social exchange can lead to detrimental interactions. Following a "tit-for-tat" pattern, the authors identify signs of reciprocity and escalation in uncivil behavior. Empirical evidence supports the association between workplace incivility and workplace withdrawal (Hülsheger et al., 2021). Our hypothesis posits that employees who experience uncivil treatment may conceal any knowledge they possess when requested by those who treated them in such a manner. Hence, we proposed the following hypotheses: H4: Workplace incivility positively influences evasive hiding. H5: Workplace incivility positively influences playing dumb. H6: Workplace incivility positively influences rationalized hiding. 2.4.2.3. Workplace Ostracism and Turnover Intention Workplace ostracism, a pervasive issue in various organizations, significantly impacts employees' mental well-being and behavior (Bedi and Skowronski, 2014). In the United States, a study involving workplace staff revealed that over two-thirds of workers have experienced exclusion or rejection from leaders or co-workers at some point in their professional history. This phenomenon diminishes employees' social cohesion, a crucial factor for optimal job performance and productivity (Özer and Günlük, 2010). While being ignored or excluded may seem relatively harmless, it has enduring negative effects on employees' well-being, attitudes toward colleagues, and actual turnover (Heaphy and Dutton, 2008). To counteract the detrimental impact of workplace ostracism, the concept of teamwork is gaining prominence, aiming to enhance employees' social cohesion for improved performance and timely achievement of job targets (Özer and Günlük, 2010). Workplace ostracism manifests in various forms, such as exclusion from conversations, colleagues leaving when one enters, sitting alone in a crowded lunchroom, lack of invitations or inquiries during coffee breaks, and being treated as if invisible (Bedi and Skowronski, 2014). These experiences contribute to turnover intentions, ultimately leading employees to leave their jobs. Employee turnover intention represents the final stage in the sequence initiated by workplace ostracism (Carpenter and Berry, 2014). Turnover can be categorized as involuntary or voluntary, with the latter occurring when an employee chooses to resign for various reasons (Haq, 2014). Voluntary turnover often results from seeking better treatment, whether physical or spiritual, in another organization (Haq, 2014). While such voluntary turnover may be positive for the employee, it raises concerns for the organization. Existing research has explored the relationship between workplace ostracism and turnover intention, but less attention has been given to job stress as a mediator in this association. Building on the existing literature, the hypothesis proposed is as follows: H7: Workplace ostracism positively influences turnover intention. 2.4.2.4. Workplace Incivility and Turnover Intention Prior studies have suggested that workplace incivility, stemming from employees' attitudes and coworkers' behaviors, contributes to job turnover or the pursuit of new employment opportunities. For instance, Bliese, Jex, and Thomas (2015) demonstrated that workplace incivility diminishes employees' intent to continue their current jobs, and Cortina's study (2001) identified a link between incivility victimization and increased turnover intention. Therefore, individuals subjected to incivility are likely to lose interest in their work, ultimately leading to a turnover intention and job replacement (Griffon, 2010; Riasat & Nisar, 2016). From the perspective of the Conservation of Resources (COR) theory, there exists a direct and significant relationship between workplace incivility and turnover intentions. Previous research indicates that undue pressure negatively impacts an individual's job handling abilities and diminishes social interactions among employees (Wright & Cropanzano, 1998; Halbesleben, 2006; Hobföll, 2001; Cole & Beeian, 2007). The resulting reduced social interactions serve as a coping mechanism, helping employees distance themselves from these stressors, ultimately enhancing job performance (Hobföll, 2001; Halbesleben, 2006). While prior studies have extensively examined the association between workplace incivility and turnover intention, they have often overlooked burnout as a mediator in this relationship. In the current organizational landscape, many face issues related to workplace incivility, leading employees to develop turnover intentions. The direct relationship between workplace incivility and turnover intention is contingent on the severity and frequency of incivility. Minor instances may be temporarily overlooked by employees, requiring time before considering job resignations and transitions. Conversely, if incivility involves attitude aggression or emotional abuse, employees are more likely to resign from their current positions. H8: Workplace incivility positively influences turnover intention. 2.4.2.5. Knowledge Hiding and Turnover Intention Establishing a competitive advantage within any organization revolves around knowledge, according to Wang and Noe (2010). Consequently, the concealment of knowledge becomes crucial as it serves as a hurdle to disseminating the organization's competitive edge to its workforce. Abundant research in the realm of knowledge exchange and its influence on employee morale emphasizes that the sharing and exchange of knowledge and information foster team cohesion and enhance organizational performance. On the flip side, knowledge hiding acts as a catalyst for the erosion of trust. The absence of trust turns the workplace into a perpetual Darwinian battleground, where employees must constantly strive for survival, and only the most adaptable thrive. This workplace atmosphere nurtures bitterness, thus mediating uncivil behaviors. Knowledge sharing and collaboration, integral to knowledge transfer (Wang and Noe, 2010), face substantial hindrances from knowledge-hiding behaviors. This pattern of concealment intensifies, giving rise to WI. Diverse forms of workplace incivility erode job satisfaction, as outlined by Viotti et al. (2021). This erosion gradually engenders discomfort with peers, contrived interactions, avoidance of workplace interactions, and an increasing desire to explore more favorable professional environments. Consequently, ensuring that employees' knowledge is accessible to various individuals and departments becomes pivotal for fostering a thriving organization (De Vries et al., 2006). Knowledge sharing is defined as a specific set of information and experiences that empower others to replicate problem-solving skills, generate new ideas, and implement unique methods and processes (Wang and Noe, 2010). Extensive research in this field demonstrates a positive correlation between both team and organizational productivity and performance and the sharing and exchange of knowledge and information (Collins and Smith, 2006; Wang and Noe, 2010). In the context of the contemporary global-local economy, where considerable value is placed on knowledge-related work, understanding the factors influencing knowledge sharing has become an increasingly significant concern ( Frost et al, 2010). Therefore, we posit the following hypotheses: H9: Evasive hiding positively influences turnover intention. H10: Playing dump positively influences turnover intention. H11: Rationalized hiding positively influences turnover intention. CHAPTER 03: RESEARCH METHOD 3.1. Research process 3.2. Measurement scale The assessment of all items is conducted using 5-point Likert-type scales, ranging from "1" (strongly disagree) through "3" (neutral) to "5" (strongly agree). Constructs Number of Sources measurement item Workplace Ostracism 10 Ferris et al., (2008) Workplace Incivility 7 Cortina et al., (2001) Evasive hiding 4 Connelly et al., (2012) Playing dumb 4 Rationalized hiding 4 Knowledge Hiding Turnover Intention 3 Kim et al. (2017) 3.2.1. Workplace Ostracism The assessment of workplace ostracism was conducted using the 10-item scale developed by Ferris et al. (2008). One example of a statement in the survey was "Others at work shut you out of the conversation", and participants rated their agreement on a 5-point Likert-type scale, ranging from "1" (strongly disagree) through "3" (neutral) to "5" (strongly agree). WO1. Others ignored you at work. WO2. Others left the area when you entered. WO3. Your greetings have gone unanswered at work. WO4. You involuntarily sat alone in a crowded lunchroom at work. WO5. Others avoided you at work. WO6. You noticed others would not look at you at work. WO7. Others at work shut you out of the conversation. WO8. Others refused to talk to you at work. WO9. Others at work treated you as if you weren’t there. WO10. Others at work did not invite you or ask you if you wanted anything when they went out for a coffee break. 3.2.2. Workplace Incivility The evaluation of workplace incivility utilized the "workplace incivility scale" created by Cortina et al. (2001). This 7-item gauge was employed to gauge the respondents' encounters with disrespectful, impolite, or condescending conduct from their immediate superiors. An example item from the scale is “Have you been in a situation where any of your superiors paid little attention to your statement or showed little interest in your opinion?” WI1. Put you down or was condescending to you? WI2. Paid little attention to your statement or showed little interest in your opinion? WI3. Made demeaning or derogatory remarks about you? WI4. Addressed you in unprofessional terms, either publicly or privately? WI5. Ignored or excluded you from professional camaraderie? WI6. Doubted your judgment on a matter over which you have responsibility? WI7. Made unwanted attempts to draw you into a discussion of personal matters? 3.2.3. Knowledge Hiding We selected 12 items from a total of 21, encompassing three facets of the scale (evasive hiding, playing dumb, rationalized hiding) to discern the adverse impact associated with possessing knowledge within a work environment. In this study, the mediating variables were three dimensions of knowledge hiding (evasive hiding, playing dumb, rationalized hiding). Each dimension of knowledge hiding was measured using a set of four items, adapted from Connelly et al.'s (2012) research. Evasive Hiding EH1. I agree to help him/her but never really intend to. EH2. I agree to help him/her but instead give him/her information different from what s/he wanted. EH3. I tell him/her that I would help him/her out later but stall as much as possible EH4. I offer him/her some other information instead of what he/she really wants Playing Dumb PD1. I pretend that I do not know the information. PD2. I say that I do not know. even though I do. PD3. I pretend I do not know what s/he was talking about. PD4. I say that I am not very knowledgeable about the topic. Rationalized Hiding RH1. I explain that I would like to tell him/her but was not supposed to RH2. I explain that the information is confidential and only available to people on a particular project. RH3. I tell him/her that my boss would not let anyone share this knowledge. RH4. I say that I would not answer his/her questions. 3.2.4. Turnover Intention The focal point of the study was turnover intention, serving as the dependent variable, and its assessment utilized a set of five items derived from the research conducted by Kim et al. (2017). TI1. I think a lot about quitting my job TI2. I am actively searching for an alternative to my present job TI3. As soon as possible, I will leave this Organization 3.3. Questionnaire design The questionnaire consists of two sections. First section includes the demographic profiles of the respondent by using nominal scale. Second section includes the questions of all variables mentioned above by using a 5-point likert scale. 3.4. Data collection The survey was translated into Vietnamese by the authors while simultaneously ensuring face validity and contextual equivalence for respondents in Vietnam since the study's participants were Vietnamese. The survey was conducted on an online survey platform to ensure that all survey participants could fill it out whenever they have time because our survey respondents are working people. Moreover, online surveys have many advantages, including the ability to be conducted from anywhere, lower survey costs, and quicker response times. Our survey subjects are people working in many different working environments in Vietnam. As a result, they were invited to answer questions related to their work situation as well as their recent turnover intention. The main purpose of this modification is to assist the response in creating a clear image or recollection that will act as the basis for concluding the survey. This modification would ensure that every response reflected the defined study model components in a way that was congruent with the respondent's subjective experience. In an effort to represent perceived experiences from many contexts involving work-related stress, the answer can become disorganized without manipulation. A bias in the data-gathering process could be prevented by data manipulation. 3.5. Data analysis method We evaluated the suggested model using structural equation models with partial squares (PLS-SEM) using the SmartPLS software. Several management and marketing studies have made substantial use of PLS-SEM due to its ability to estimate sophisticated statistical models. The consistency, value, and dependability of the indicator are used to assess the measurement model. Each indicator's requirements are properly followed: The outer loadings of indicators should be greater than 0.7, Cronbach's alpha should be at least 0.6 and the average variance extracted (AVE) should be over 0.5. The model's variance inflation factor (VIF), which should be 3 or less, is then assessed. After that, the precision of PLS estimates is verified using a bootstrapping procedure REFERENCES with 5000 samples.
