Concepts of organizational commitment, organizational justice and organizational trust have been examined extensively in organizational behavior literature, however, relationships and effects of distributive justice, procedural justice and organizational trust on affective commitment have received scarce attention at Hospital in Turkey. In this paper, we evaluated the relationships and impacts of distributive justice, procedural justice and organizational trust on affective commitment. In this study, hypotheses were tested by multiple regression models with the data from health employees (medical doctors, nurses, medical secretaries, office staff and biomedical technicians) of Kocaeli University Research Hospital in Turkey. Results suggest that the employees’ perceptions of affective commitment is positively affected by their perceptions of distributive justice, procedural justice and organizational trust. Hence, if managers understand this effect and their role in developing and fostering it, they will contribute to increase their organizational performance.
