The purpose of this study is to empirically test the effects of employees` perceived organizational support (POS) on service quality, customer satisfaction, and customer loyalty in health care organizations. The proposed research model was tested using structural equation modeling based on data collected from 193 pairs of employee-customer respondents in private and public hospitals with more than 500 beds. The results indicate that hospitals can improve the efficiency of their operations through POS for customer satisfaction and customer loyalty. One of the key findings of this study is that POS in health care organizations influence the service quality. Also, employee satisfaction is "an important determinant of operational performance", it leads to higher service quality and that it directly effects customer satisfaction because high-contact service industries have close interactions activities in employees and customers.
