The welfare of dual earner families is a challenge along with the potential conflicts and challenges of family transactions with their environment. The purpose of this study was to analyze the influence of time management, family work balance, family transactions with their environment, and family-friendly environment on subjective well-being in dual earner families. The cross-sectional study involved 120 wives of dual earner families with school-age children who were selected by simple random sampling from the population in Kelurahan Pasir Jaya and Gunung Batu, Bogor City. The results showed that most of the sample had high subjective well-being and family-friendly environment indices, but had moderate indices of time management, family work conflict, family work balancing strategies, and family transactions with the environment. The PLS test results show that family work balancing strategies and a family-friendly environment have a positive effect on subjective well-being. Time management indirectly affects subjective well-being through family work balancing strategies.
