Work-Life Balance (WLB) is a critical factor influencing employee performance and Organisational Commitment, particularly in the public sector, where rigid structures and high workloads can undermine employee engagement. This study empirically investigates the relationship between Work-Life Balance and Organisational Commitment among employees of Ministries, Departments, and Agencies (MDAs) in Gombe State, Nigeria. The main objective was to assess how Work-Life Balance practices impact employees’ affective, continuance, and normative commitment. A cross-sectional research design was employed, targeting the population of staff in the selected MDAs. Using the Taro Yamane formula, a sample of 400 employees was drawn for the study. Data were collected through structured quantitative questionnaires, and the responses were analysed using SPSS software to generate descriptive and inferential statistics. The findings revealed that effective Work-Life Balance practices, including flexible work arrangements, workload management, leave policies, and family-supportive practices, are positively associated with Organisational Commitment among public sector employees. Employees who reported higher Work-Life Balance levels demonstrated stronger loyalty, engagement, and intention to remain in service. The study concludes that Work-Life Balance is a significant determinant of Organisational Commitment in the Nigerian public sector, and that addressing work-life conflicts can enhance employee productivity and institutional effectiveness. Consequently, it recommends that MDAs implement policies that promote flexible schedules, manageable workloads, supportive leave arrangements, and family-friendly practices to strengthen employee commitment and improve public service delivery in Gombe State.
