This study, based on the sample of C Supermarket employees, explores the measurement of total rewards satisfaction and its influence on employees' job performance, the mediation function of employees' engagement, and the moderating effect of total rewards communication. The results of the study show that the total rewards satisfaction of the retail enterprises is composed of five dimensions, i.e. the satisfactions of employees' salary, career development opportunities, performance recognition, work-life balance and that of benefits. Of these dimensions, the satisfactions of job performance recognition and work-life, contrary to the rest three, have significant positive effects on job performance. Moreover, all the five dimensions are of significant positive effects on employees' work engagement, while the satisfactions of employees' job performance recognition and that of their work-life balance, through their work engagement, impact on employees' job performance. In addition, total rewards communication positively moderates impacts of employees' work engagement brought about by their job performance recognition satisfaction, lifework balance satisfaction, and that of work benefits, as well as the mediating effect between the satisfactions of job performance recognition, lifework balance and work benefits, and employees' job performance, i.e. the higher the total rewards communication is, the stronger the mediating effect of employees' engagement becomes.
