An effort to fully understand the interface of work-family conflict and social support can be observed in the psychological research for more than three decades. This study explored relationship between different sources of social support and work-family conflict in its both directions and three forms. Work-family conflict was measured by the Work-family conflict scale (Carlson, Kacmar, Williams, 2000), whereas social support was measured by twelve items constructed for the purposes of the present study. The data were collected via on-line questionnaire during the period of two-months (October 2013 – November 2013). The sample comprised of 100 participants both female (n=64) and male (n=36), working full-time, married and had one or more children. For women the results suggested that the only effective support that significantly reduces work-family is social support obtained from direct supervisor. Specifically supervisory support reduced perceived work interference with family caused by strain. For men the results indicated that collegial support significantly reduced work interference with family and vice versa in its behavioural aspect. Furthermore supervisory support significantly decreased work interference with family. However at the same time supervisory support increased family interference with work. Finally both spouse and broad family support significantly reduced family interference with work for men. This study contributes to enhanced understanding of the relationships between social support and work-family conflict in our region.
