The present study examines the relationship between four sources of social support (i.e., spouse, relatives and friends, supervisor, and colleagues) and time and strain-based work-to-family and family-to-work conflict among 444 dual-earners. Gender differences with respect to the relationship between social support and work-family conflict were examined as well. The relationship between the sources of support and work-family conflict was tested using multiple regression analyses. Results showed that women reported more strain-based work-to-family conflict than men. Social support from spouse and from colleagues were related to family-to-work conflict, while none of the sources of social support were related to work-to-family conflict. Social support from supervisor and from colleagues were related differently to work-to-family conflict (time-based) and family-to-work conflict (strain-based) for men than for women. We conclude that social support is especially important in reducing family-to-work conflict.
