This paper proposes a mediating model and tests the impacts of internal marketing mechanisms on employees' job satisfaction and their organizational commitment. Using 427 banking industry employees as research samples, empirical results indicate that banks' internal marketing mechanisms positively influence employees' job satisfaction, which, in turn, has positive influence on their organizational commitment. The impacts of internal marketing mechanisms on employees' organizational commitment are partially mediated by employees' job satisfaction. Managerial implications, research limitations, and future research suggestions are also proposed.
