The main purpose of this study is to examine the relationship among organizational commitment, professional commitment, Organizational – professional conflict, turnover intentions and job satisfaction for a sample of Iranian certified public accountants. The relationship among variables was tested by using structural equations modeling. As hypothesized, results indicate accountants' organizational commitment has a significant negative influence on organizational – professional conflict, which, in turn, has a significant positive influence on turnover intentions and a significant negative influence on job satisfaction. The findings also show that within accounting firms, the higher position of the accountant in the hierarchy of the firm, his level of organizational – professional conflict decrease and his level of organizational and professional commitment increase.
