This study examined whether work–family support (WF support) buffers permanent and temporary workers similarly against the negative effects of work–family conflict as regard job satisfaction and emotional energy level at work and at home. A total of 1,719 Finnish nurses participated in this study in 2009. The results revealed that high coworker WF support protected temporary workers against the negative effects of high work–family conflict on emotional energy at work. Furthermore, temporary workers with low coworker WF support were at greater risk of job dissatisfaction and diminished emotional energy at home than were their permanent colleagues in the presence of high work–family conflict. Temporary workers may benefit more from coworker WF support if they experience work–family conflict. This should be considered in developing family-friendly practices in organizations where temporary contracts are relatively common.
