The comparison between self-expectations and perceived situations of one organization usually affects people’s perception of work. The present study proposes that perceived organizational health is a mediator for the relationships between job expectations and job self-efficacy, and between job expectations and job satisfaction. Also, job self-efficacy plays a mediating role between perceived organizational health and job satisfaction. The questionnaires were developed for Chinese participants. Data were collected from 477 junior employees in the public bus companies. Results indicated that the first two propositions had been confirmed. Both of them produced a complete mediating effect. Then they were combined and fitted in the same model, of which the fitness was good. The research outcomes were consistent with the social cognitive theory. Strengths, limitations, and future orientations have been discussed.
