This research aims to analyze the impact of occupational safety and health management and achievement motivation on employee productivity at PT. XYZ (Persero). This study employs a mixed-method approach, combining quantitative surveys and qualitative analysis. Data was collected from PT. XYZ (Persero) Transmission Implementation Units (UPT) in Bogor and Karawang over the period from 2017 to 2021. The results indicate that effective occupational safety and health management and achievement motivation have a significant positive impact on employee productivity. Both directly enhance productivity, although achievement motivation as a mediator is less effective than the direct influence of occupational safety and health management. The conclusion of this study is that improving the effectiveness of occupational safety and health management and achievement motivation can significantly boost employee productivity at PT. XYZ (Persero). Recommendations for the company include enhancing occupational safety and health training, monitoring the work environment, and developing reward programs for high-performing employees.
