Although researchers have argued that long work hours have been shown to threaten individual health, lead to work-family conflict, and reduce job performance, the effect of overtime work on social-related outcomes has received little attention. Based on the framework of relative deprivation, we attempt to address this important issue by exploring whether, why, and when individuals' overtime work influences their social attitudes. By using the data of 400 Chinese employees from the China Labor-Force Dynamics Survey (CLD), we found that overtime work was associated with a low level of subjective social status and social inclusion. In addition, we found that the time type of overtime work (work overtime on weekdays or on weekends and holidays) has a moderating effect on the relationship between overtime work and social inclusion. That is, employees who work overtime on weekdays are unlikely to have a sense of social inclusion. Furthermore, the negative relationship between overtime work and subjective social status was stronger at a low level of fairness rather than a high level of fairness. In contrast, the negative relationship between overtime work and social inclusion was stronger at a high level of fairness rather than a low level of fairness. These findings highlight the critical role of overtime work in social life and also provide novel insights into social intervention aimed at the happiness and harmony of a society.
