Abstract:
This paper examines the effect of overtime work on employee productivity. We measure firm overtime level using the data from employees’ textual comments on a leading online website for employee reviews and recruitment in China. Our results show that firms with higher overtime level tend to have lower employee productivity. Our findings are robust after addressing possible endogeneity issues, and using alternative measures of firm overtime level and employee productivity. Employee satisfaction appears to be the channel, through which overtime work affects employee productivity. Finally, we find that the negative relation between firm overtime level and employee productivity is stronger for firms with higher ratio of the key word “overtime” in the comments, stronger external monitoring, higher proportion of low-skilled employees, more negative tone of the comments, and time off in lieu policy. Our study highlights the negative economic consequences of overtime work, and demonstrates the importance of time management at work.
