The objective of the current study is to estimate the determinants of overtime work using a dataset from an aluminum manufacturing facility, Istanbul, Turkey. The results of hierarchical regression analysis revealed that production volume and production unit (work factors) and annual paid leave, sickness absence and other paid leaves (employee factors) were positive determinants of overtime work. Moreover annual paid leave was found to be a negative predictor of overtime in a sub-sample of the production units. Finally, the findings of the correlation analysis for the full sample pointed out that overtime was positively and significantly correlated with production volume, operational team, annual paid leave, sickness absence and other paid leaves.
