Purpose: This study examines the effects of occupational safety and occupational health on employee performance at PT Telkom Indonesia Witel East Jakarta, addressing limited evidence from the Indonesian state-owned telecommunications sector.

Research Methodology: A quantitative survey was conducted using saturation sampling of all 60 employees in the SAS Division. Data were collected through Likert-scale questionnaires and analyzed using Multiple Linear Regression (MLR) in SPSS 25. Instrument validity, reliability, and classical assumption tests were performed before hypothesis testing.

Results: All instruments were valid and reliable. The regression model met normality, multicollinearity, and heteroscedasticity assumptions. The regression equation was Y = 6.619 + 0.275X1 + 0.333X2. Partial t-tests showed that occupational safety (t = 3.044, p = 0.004) and occupational health (t = 2.401, p = 0.008) significantly affected employee performance. The F-test confirmed a significant joint effect (F = 14.161, p < 0.001). The model explained 33.2% of the variance in employee performance (R² = 0.332).

Conclusions: Occupational safety and occupational health positively and significantly influence employee performance, both individually and simultaneously. These findings indicate that strengthening workplace safety and health programs can contribute to improved employee productivity and organizational performance.

Limitations: The study focuses on a single division within one company, limiting generalizability. Additional organizational factors may explain the remaining performance variance.

Contributions: This study provides empirical evidence on the Occupational Health and Safety (OHS) performance relationship in an Indonesian state-owned telecommunications company and supports evidence-based OHS policy development.
