The aim of this study is to determine the organizational performance level of employees and the relationship between them. The sample of the study consists of 309 participation bankers working in Istanbul. In the study, it was found that as the emotional and normative commitment of the employees in the participation bank increased, their work performance increased but decreased due to their attendance commitment. In addition, it was found that 7.8% of the study performance was positively explained by emotional commitment and negative by continuation commitment, and normative commitment did not make a significant contribution to performance. It was found that the organizational performance of the employees did not differ according to the gender, education, job position variable and there were significant differences according to age, marital status and year worked
