Why Are Your Employees Leaving the Organization? The Interaction Effect of Role Overload, Perceived Organizational Support, and Equity Sensitivity

Drawing on job demand-resources (JDR) theory, this study proposes that role overload and perceived organizational support have interaction effects on turnover intention. Further, we investigate the dynamics between role overload and turnover intention by considering differences in individuals’ reactions to inequity. We conducted several hierarchical regression analyses to test our hypotheses using data from 207 team members at 12 manufacturing companies in South Korea. The results reveal a positive relationship between role overload and turnover intention and a significant joint moderation effect of perceived organizational support and equity sensitivity. This study expands on JDR theory by simultaneously considering the buffer and strain hypotheses in the role overload–turnover relationship and its link to equity sensitivity.
