The Effect of Work-Family Conflict and Workload on Work-Life Balance: The Moderating Role of Family Supportive Supervisor Behavior and Coworker Support

The issue of work-life balance has garnered significant scholarly and organizational attention, particularly in the context of escalating work demands. This study investigates the impact of work-family conflict and workload on employees' work-life balance, while also examining the moderating roles of family supportive supervisor behavior and coworker support. A quantitative research design was employed, utilizing a survey distributed to 222 employees of the Central Bureau of Statistics in West Sumatra, selected through cluster random sampling. Data were analyzed using Structural Equation Modeling with Partial Least Squares (SEM-PLS). The findings indicate that both work-family conflict and workload negatively influence work-life balance. Furthermore, coworker support was found to buffer these adverse effects, whereas family supportive supervisor behavior did not exhibit a moderating influence. This research contributes to the literature by highlighting the differential roles of workplace social support mechanisms in mitigating work-life imbalance. The practical implications underscore the need for organizations to foster peer support systems to enhance employee well-being and sustain productivity in high-demand environments.
