What is it about?

The study delivers concerning news about involuntarily part-time work. Involuntary part-timers have a significantly higher probability of transitioning into unemployment compared to full-time workers. Individuals working part-time due to care responsibilities were more likely to experience frequent periods of unemployment, while part-time employment combined with studies was associated with stable white-collar career paths. The results also indicate that diminished labor outcomes resulting from marginal part-time employment are more likely to be associated with disability retirement, rather than subsequent unemployment, most likely due to health-related reasons. We utilized the Finnish Labour Force Surveys merged with register-based follow-up data and employed sequence analysis to categorize work career clusters based on the duration of spells spent in various labor market statuses.

Why is it important?

We suggest further studies to consider marginal part-time workers’ health as the determinant of weakening career outcomes. Overall, our results highlight the need to improve part-time working conditions. This improvement could reduce the risk of unemployment, promote health, extend work careers, and consequently increase the employment rate.


Our study stemmed from the observation that longitudinal studies on part-time work typically do not analyze part-time work in enough detail. Part-timers are a heterogenous group whose employment outcomes are determined by the reason for working part-time.
