The difference a manager can make: organizational justice and knowledge worker commitment

The quality of the employment relationship is argued to be central to knowledge workers' commitment, which in turn supports knowledge creation. Given the high levels of discretion enjoyed by knowledge workers, managers' decisions over work distribution, content and resources become more critical for commitment and knowledge creation. However, little research has explored how justice perceptions shape the quality of the employment relationship and the consequences for commitment. Using a sample of 429 R&D workers from across six science and technology-based firms this paper explores the three-way interaction of procedural and interactional justice with the psychological contract to predict knowledge worker commitment. We found that when employees simultaneously perceived high levels of procedural and interactional justice this moderated the relationship between psychological contract breach and knowledge worker commitment. Furthermore, where there was contract breach, positive perceptions of procedural justice moderated the relationship with commitment. However, in the context of contract fulfilment, low perceived levels of interactional justice predicted lower comparative levels of commitment, regardless of the level of procedural justice. The results suggest that the perceived quality of the relationship between knowledge workers and their manager can make a positive difference in the context of breach of the psychological contract and this in turn can help maintain levels of commitment important for knowledge creation.
