Background and Objective: Inappropriate workplace design and neglect of ergonomics and safety reduce productivity and increase organizational costs. This study aimed to investigate the relationship between safety climate and ergonomic climate with individual performance and the approximate PALY index.
Methods: This cross-sectional analytical study was conducted in 2025 with 420 employees from six food companies in Urmia, Iran. Data were collected using validated questionnaires for safety climate, ergonomic climate, individual work performance, and a productivity evaluation form was employed to calculate the approximate PALY index. Data were analyzed using Mann-Whitney U, Kruskal-Wallis, Spearman's correlation, and linear regression.
Results: A strong positive correlation was found between safety climate and ergonomic climate (ρ = 0.84, p < 0.01). Safety climate showed a weak positive correlation with individual performance (ρ = 0.12, p = 0.01). Multiple linear regression revealed that ergonomic climate (β = 0.28, p < 0.001) and company of employment (β = -0.31, p < 0.001) were significant predictors of individual performance, whereas work experience (β = 0.87, p < 0.001) and company of employment (β = -0.08, p < 0.001) were significant predictors of the approximate PALY index.
Conclusion: The strong correlation between safety and ergonomic climate highlights them as synergistic components. Ergonomic climate (not safety climate) is an independent predictor of individual performance, while work experience is the strongest predictor of the approximate PALY index. The lack of association between self-rated performance and the approximate PALY index reveals a deep perceptual gap between employee self-assessment and managerial evaluation
