Abstract

The purpose of this study is to analyze the effect of return to work on the health recovery of workers who have experienced industrial accidents. While previous research has primarily focused on the impact of health status on the return-to-work outcomes of injured workers, relatively little attention has been paid to the reverse relationship—that is, how return-to-work outcomes affect health recovery. However, labor market participation is not only a means of livelihood but also an opportunity to access a variety of social resources. From this perspective, failure to return to work can serve as a trigger for resource deprivation. In particular, this study examines how non-return to work influences health outcomes among older injured workers, a group that is both more vulnerable in terms of health and faces greater barriers to reemployment. To this end, we conducted multiple regression analyses using difference-in-differences(DID) and difference in difference in differences(DDD) designs with propensity score-based weighting. The results show that the effect of return to work on health recovery is more pronounced among workers aged 60 and above. Moreover, even when these workers returned to jobs with less stable employment conditions compared to their pre-injury positions, return to work still had a more positive effect on health recovery than non-return. These findings suggest that sudden labor market exit due to work-related health problems is particularly detrimental to the health of older workers. Therefore, it is necessary to strengthen return-to-work support policies for older injured workers, and when return is not feasible, to provide programs that help maintain livelihood, social relationships, and physical activity so as to prevent the negative health consequences of labor market exit.
