Abstract

The purpose of this study was to investigate the influence of role stress(role conflict, role ambiguity, and role overload) on employee silence behavior and the mediating effect of psychological ownership between two variables. In addition, this study examined the moderating effect of perceived supervisor support on the relationship between psychological ownership and employee silence behavior. Using the survey research method, data were collected from 310 employees who were working in a variety of organizations in Korea. As results, role conflict, role ambiguity, and role overload had positive relationships with employee silence behavior. And psychological ownership had mediation effect in the relationship between role conflict/role ambiguity and employee silence behavior. The perceived supervisor support had moderation effect on the relationship between psychological ownership and employee silence behavior. That is, the negative relationship between psychological ownership and employee silence behavior was stronger when the perceived supervisor support was high rather than low. Finally, based on these results, we discussed the implications and limitations of the study, and the suggestions for the future research.
