The power of employee exchange belief: How psychological contract strength mediates the relationship of HR practice consistency and organizational commitment

This study examines the concept of the psychological contract strength deriving from an employee’s expectation of mutual exchange with regard to their employers’ obligation fulfillment. This study explores the role of psychological contract strength and the relationship between the human resources (HR) practice consistency and organizational commitment. We collected data from 226 employees in 50 medium to large enterprises across the manufacturing and service industries in Taiwan. The results support the proposed hypotheses and provide theoretical and empirical contributions, highlighting the importance of the psychological contract strength. This study also advocates for consistency in HR practice as a key antecedent for creating favorable conditions for increased employee exchange belief. This study is the first to investigate the constitution of employee exchange belief, in emphasizing the concept of the psychological contract strength. Therefore, it complements our understanding of an organization’s ability to harness employees’ efforts more effectively, by enhancing the strength of the psychological contract.
