Psychological contract breach,high-performance work system and engagement: the mediated effect of person-organization fit

Based on social exchange theory, we developed and tested a mediated moderation model to investigate the effects of psychological contract breach (PCB), person–organization fit (P–O fit) and high-performance work system (HPWS) on employee engagement. Using a sample of 255 employees in China, our results revealed that PCB has significant negative effect on employee engagement, and P–O fit partially mediates this relationship. We further found that high levels of perceived HPWS aggravate not buffer the negative effect of PCB on employee engagement and P–O fit. In addition, the interaction of HPWS and PCB on employee engagement is mediated by P–O fit. Implications for the research and practices, limitations and directions for future research are discussed.
