Reconciling work and personal life is a complex topic due to the needs of dealing with demands from professional and family spheres. With a sample of 111 assembly line workers from an industrial company, based on the Job Demands-Resources JD-R model, the importance of work context demands and resources in predicting work-family conflict were assessed. At the level of demands, quantitative, cognitive, and emotional demands, (un) fairness and pace of work were evaluated, and at the level of resources, support from peers and supervisors, as well as community belonging, and rewards were considered in the study. The results of the linear regressions showed that only emotional demands, work pace and rewards predicted the work-family conflict in this sample. The results obtained are discussed in the context of studies on the work-family conflict.
