Purpose: Drawing on the conservation of resources theory and social exchange theory, this study aims to examine the underlying relationships linking work-to-family enrichment (WFE) and family-to-work enrichment (FWE) to perceived supervisor support and ultimately, job satisfaction among social workers. Design/methodology/approach: Data were collected from members of a social work professional body (n = 439) through an internet-based questionnaire and analysed using confirmatory factor analysis and structural equation modelling. Findings: Perceived supervisor support mediated the relationships between work–family enrichment (specifically, WFE-Development, WFE-Affect and FWE-Efficiency) and job satisfaction. Research limitations/implications: Social workers who worked in a positive work environment that uplifts their moods and attitudes (WFE-Affect), have access to intellectual and personal development (WFE-Development) and felt supported by their supervisors reported higher levels of job satisfaction. Those who possessed enrichment resources were found to be more efficient (FWE-Efficiency) also perceived their supervisors to be supportive and experienced higher job satisfaction. Future studies should consider other professional groups and incorporate a longitudinal design. Practical implications: Promoting work–family enrichment among social workers can contribute to positive work outcomes such as perceived supervisor support and job satisfaction. HR practitioners, supervisors and organisations can promote work–family enrichment among social workers through introduction of family-friendly policies (e.g. flexitime, compressed workweek schedules) and providing a supportive work–family friendly environment for social workers. Originality/value: Although several work–family studies have linked work–family enrichment to job satisfaction, the present study shows how each dimension of WFE and FWE affects social workers' job satisfaction.
