This paper provides a systematic review of the theoretical and empirical literatures on Organizational Commitment in three periods, the 1990s, 2000-2010 & 2010-2020 and the traditional theories of Organizational Commitment by Porter and Becker. In each period, highlight theories and findings are presented and explained with note to the antecedents of OC and the changes in these antecedent factors. Toward the final note of the paper, some new trends of empirical study of OC were presented in light of generation gap and different organization types. |
