Working time variation and mental health during the Covid-19 pandemic in China

The Covid-19 pandemic has brought about a significant shift in labor market dynamics, leading to a notable increase in labor market flexibilization. One prominent aspect of this transformation is the growing variation in working time patterns. The irregular and unpredictable nature of working time may contribute to increased stress levels, difficulty in establishing routines, and challenges in maintaining work-life boundaries. Drawing on China General Social survey 2021, this study aims to examine (1) the relationship between working time variation and mental health during the Covid-19 pandemic in China; (2) whether the relationship can be mediated by work-family conflict; (3) to what extent the relationship varies across occupations. We find that working time variation is associated with significantly worse mental health during the Covid-19 pandemic in China, and around half of the negative effect can be mediated by increased work-family conflict. Moreover, the negative association is more pronounced among non-professional occupations than professional occupations. Overall, these findings shed light on the detrimental impact of working time variation on mental health and its potential mechanism, highlighting how novel work paradigm may interact with existing labor market inequalities to shape workers’ mental health.
