This paper examines the effect of faculty rank, satisfaction with salary, working conditions, institutional reputation, perceived influence on institutional policies, participation in meetings, and perceived governance on organizational commitment (at both the departmental and institutional level) using a representative sample of 4,925 faculty. Study results revealed that although satisfaction with salary and working conditions was not significant in predicting commitment to the department it was significant in predicting commitment to the university. Full professors were found to be significantly more committed to the institution than lower ranked professors. Regression analysis revealed the importance and the power of faculty members' perceived influence on policy and participation in meetings were powerful predictors of organizational commitment. This finding suggests that, to increase faculty members' commitment to both the department and the institution, it is important for campus leaders to strive for participatory policy decision making. Findings also suggest that faculty exhibit more commitment to the department than to the institution across all ranks, with full professors exhibiting the highest commitment scores.
