This study examines the relationship between breach of psychological contract, organizational cynicism and union commitment among hospitality sector personnel in Pakistan. Data were collected from 279 unionized employees working in different hotels and also from aviation hospitality staff. Findings indicate that breach of psychological contract results in union commitment among hospitality sector employees and this relationship is mediated by organizational cynicism. Contrary to expectation collectivism does not moderate the relationship between organizational cynicism and union commitment. Implications and future research directions for hospitality management are also discussed
