Organizational commitment, as the relative strength of an individual's involvement in and identification with a particular organization, is a crucial issue in current restructured health care settings. Organizational commitment is a multidimensional work attitude, determined to include affective, continuance, and normative commitment. Allen and Meyer (1990) have demonstrated that organizational commitment positively associated with job satisfaction, job retention as well as job performance. In this study, organizational commitment is defined by Lin, Zhang, and Fang (2001) as the strong desire of an employee to maintain membership of an organization. He described five components of organizational commitment: affective, normative, ideal, economic, and opportunity commitment. Affective commitment refers to an employee's emotional attachment to and identification with the organization. The employee is willing to consecrate to the survival and development of the organization, even without any kind of reward, and never consider job-hopping in any temptation.
