Although it has been previously observed that organizational identification consists of multiple dimensions, the relative effect of each dimension on performance outcome, for example, job satisfaction, remains largely overlooked. Thus, the present study attempted how each dimension of organizational identification affects job satisfaction, which in turns affects customer orientation in the casino context. A total of 260 employees working in two casino companies in Seoul were selected as a study sample. The results of this study confirmed that three aspects(i.e., affective, cognitive, and evaluative identification) of organizational identification could be distinguished as separate factors in a principal analysis, and all three factors had an signigicant effect on job satisfaction. Out of three factors, affective identification had the most strong relationship with job satisfaction. In addition, job satisfaction affected customer orientation positively and significantly. Furthermore, implications were discussed and a few things in the conclusion based on this research findings were suggested.
