The study investigated the mediating effect of job satisfaction on health and safety policy management and employee productivity in manufacturing firms in Nigeria. For the study, a quantitative analytical method was adopted, including a descriptive survey. To obtain data for the study, a questionnaire instrument was constructed and distributed among 950 sampled respondents in selected manufacturing firms in Nigeria. The descriptive statistics was deployed in the data analysis, while the multiple regression analysis was used to test the study hypotheses at the 0.05 level of significance. The mediating effect of job satisfaction on health and safety policy management and employee productivity relationship was confirmed using the Sobel test with the aid of MedGraph. The results showed that hazard prevention and control policy have a significant positive effect on employee productivity. Risk assessment policy have a significant positive effect on employee productivity. Also, job satisfaction has a significant positive mediating effect on the health and safety policy management and employee productivity relationship. Therefore, manufacturing firms should take appropriate measures to prevent and control hazards and provide effective risk assessments to improve health and safety policy management.
