Little research analyzes the mediator effects that may exist between work commitment, perceived social support, work-life balance, and job satisfaction. This study, conducted among 224 private sector executives, shows that perceived work-life balance is a mediator on two levels. First, it is a mediator of the relationship between perceived social support and job satisfaction, although it is supervisor support on both work-related and family issues that contributes most to that relationship. Indeed, supervisors must increasingly manage work-life boundaries, leading to questions about changing managerial roles and skills. Second, it is a mediator of the relationship between work commitment and job satisfaction, which reflects changing employee expectations regarding better quality of work life.
