This study investigates the mediating role of job satisfaction in the relationship between work environment dimensions—physical, psychological, and social—and employee organisational commitment within the public sector. Using survey data from 124 employees of the Ministry for Local Government in Yobe State, Nigeria, the analysis employed Partial Least Squares Structural Equation Modelling (PLS-SEM). Results revealed a strong direct effect of job satisfaction on employee commitment (β = 0.701, p < 0.001). Among the work environment dimensions, the social work environment had a significant positive effect on job satisfaction (β = 0.444, p < 0.01) and an indirect effect on employee commitment via job satisfaction (β = 0.311, p < 0.01). However, the physical and psychological work environments did not exhibit significant direct or mediated effects. These results underscore the central role of fostering a supportive and holistic work environment in public sector organisations to enhance employee satisfaction and commitment. Practical recommendations include strategic investments in workplace facilities, psychological support systems, and social cohesion initiatives.
