Despite the ongoing public debate about precarious working conditions in academia, there is only little evidence on working hours and overtime work for the group of (non-tenured) junior academics. We make use of unique longitudinal survey data on the occupational situation and careers of doctoral students and doctorate holders in science, technology, engineering and mathematics fields in Germany. We find that overtime hours are less pronounced among firm employees holding a doctorate and among postdocs than they are among doctoral students. This result is prevalent both between individuals in the cross-section and with regard to individual fixed effects panel estimations. In contrast to firm employees, overtime hours are in a considerable way positively associated with part-time contracts for doctoral students. Furthermore, our results reveal that individuals’ career orientation is positively associated with extra hours. In contrast, individuals with family responsibilities spend significantly fewer hours at work.
We examine the role of working-time mismatches (defined as the difference between actual and desired weekly working hours) in academics’ job satisfaction. In doing so, we investigate how academics’ career stage (predoc vs. postdoc) and contract status (part-time vs. full-time employment) moderate the relation between a mismatch in working hours and job-related well-being. Our results are based on longitudinal survey data among junior academics in the STEM fields indicate that mismatches in working hours are prevalent in academia and are associated with a loss of job satisfaction. In this context, overemployment (working more than desired) tends to unfold more severe consequences with respect to job satisfaction compared to underemployment. We find evidence for a similar reaction of doctoral students and postdocs with respect to job satisfaction when experiencing a working-time mismatch. Part-time employment positively moderates the link between working-time mismatch and job satisfaction for the case of underemployment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
