This article explores the gendered impact of school closures on paid work hours during the COVID-19 pandemic in Austria. Using data from the Austrian Corona Panel Project (ACPP) covering generalized school closures from March 2020 to April 2021, the study examines adjustments in work hours by gender and parental status. The descriptive data show general reductions in work time, especially in the first months. From July 2020 onward, however, mothers reduced work hours more than fathers when schools were closed – and they increased time spent on childcare, while fathers reduced theirs. Using OLS and fixed effects models, the study confirms that mothers reduced their work hours during school closures more than any other group. In contrast, fathers reduced their work hours the least – even less than individuals without children. Finally, there is some evidence that school closures capture policy stringency in high-incidence phases of the COVID-19 pandemic. HIGHLIGHTS In Austria, mothers reduced paid work time more than fathers in response to pandemic school closures. In contrast, fathers reduced their work time even less than individuals without children. School closures thus triggered a gendered labor market response among parents. The additional unpaid care work burden on women is a potential mechanism for these effects. COVID-19 policy responses may have exacerbated existing gender differences in the labor market.
