摘要:The relationship between attitudes and behaviours, and particularly organizational citizenship behaviour (OCB), is discussed and a model is built asserting that job satisfaction mediates the relationship between normative commitment and loyal boosterism.It has been hypothesized that job satisfaction mediates the relationship between normative commitment and OCBs.This mediation is further developed by arguing that loyal boosterism – one of the four OCB dimensions – has stronger mediation effect, compared to the other dimensions, personal industry, interpersonal helping and individual initiative.646 individuals equally drawn from private and public sector in Greece responded to a structured questionnaire.The results validate the hypotheses, showing that job satisfaction mediates the relationship between normative commitment and OCB.Also, job satisfaction mediates the relationship between normative commitment and loyal boosterism, more strongly than the other dimensions.Finally, the limitations of the current field research, the implications are discussed and suggestions for further research are proposed.
