12877 The congruence of high performance work performance perception and work team Performance ABSTRACT This study follows previous research to call a set of coherent human resource management practices as the high performance work system (HPWS). Based on arguments in the situational strength theory, we propose that, in a work team, when the team member’s perception of the company’s HPWS concurs with that of the team manager, the worker will exhibit better work performance as well as helping behaviors to colleagues. We also argue that the dispersion of team members’ HPWS perceptions may moderate the relationship between team members’ perceived HPWS and performances. With survey data collected in Taiwanese firms, we find support for our arguments. The significance and limitations of our study are discussed.
