Beyond the <i>precariat</i>: Trajectories of precarious work and its determinants in South Korea

Abstract This study examines the evolving patterns of precarious work in South Korea over a 20‐year period, challenging conventional understandings of labour market segmentation and class formation. Using group‐based trajectory modelling on Korean Labour and Income Panel Study data (2002–2021), we identify five distinct trajectories of labour market experiences. Our findings reveal that 34.4% of the sample, categorised into persistently high precariousness and persistent precariousness groups, provides evidence for an emerging, heterogeneous precariat class. This new class formation transcends traditional occupational boundaries and challenges existing class theories. Multinomial logistic regression shows that low‐skilled service workers and women are more likely to belong to precarious groups. Our study contributes by (1) providing empirical evidence for a diverse precariat class, (2) demonstrating the need for a multidimensional approach to precarious work, and (3) highlighting the dynamic nature of precarious work over time. We argue for bringing class discussion back into labour market inequality analysis through a new theoretical framework that synthesises traditional class theory with contemporary precariat discourse, offering insights for policy and theoretical development in understanding modern labour markets.
