This study examines relationships between support from work, family and community domains with time- and strain-based work-family conflict in a sample of low-income workers. Results reveal significant within-domain and cross-domain relationships between support from all three life domains with work--family conflict. With respect to family support, support from children was associated with lower time- and strain-based family interfering with work and extended family support was associated with lower strain-based work interfering with family. Non-work support other than family was also important. Neighbor support was related to lower time-based family interfering with work. Community support was related to reduced time and strain-based work interfering with family and strain based family interfering with work. At work, family-supportive organizational perceptions and supervisor support were related to lower time-based work interfering with family. Findings highlight the need to adopt a more comprehensive approach when examining sources from which low-income employees draw social support. (Contains 3 tables.)
