While a direct relationship between family support and job satisfaction has received empirical support, few work–family studies have examined how family support leads to job satisfaction. Drawing on the work–home resources model, we investigate the chain mediating roles of work‐to‐family enrichment (WFE), family‐to‐work enrichment (FWE), and job‐related well‐being on the relationship between family support and job satisfaction. Based on data collected from 439 social workers across Australia, structural equation modeling results revealed that the chain mediating effects of WFE and job‐related well‐being were supported. Our findings emphasize the important combination of work–family enrichment and job‐related well‐being in helping employees to harness support from their family members to achieve job satisfaction. We discuss both the theoretical and practical implications of the WFE, FWE, and job‐related well‐being mechanisms underlying the family support–job satisfaction relationship.
