The effects of psychological contract breach on union commitment

This research investigates the relationship between psychological contract breach and union commitment among 109 union employees. As expected, psychological contract breach is positively related to commitment to the union. The results also suggest that union instrumentality moderates the relationship between psychological contract breach and union commitment. Specifically, the findings indicate that the relationship between psychological contract breach and union commitment is stronger when individuals perceive that their union is highly instrumental in protecting their rights and benefits. Implications of this study are discussed and recommendations for future research are offered.
