This study explores the career changes of young adult Polish migrants in the UK over the past two decades. Using data from British public statistics – the Annual Population Survey (APS) and in-depth interviews – we comprehensively analyse their labour market positionalities in the UK. Our findings reveal a shift from initial deskilling and confinement to the secondary labour market to diverse, upwardly mobile career changes. This study emphasises the critical role of practical skills, work ethics, experience, and social networks in migrants’ professional development. This research contributes to the broader discourse on post-EU enlargement of Central and Eastern European migration, providing a nuanced understanding of young adult Polish migrants’ labour market experiences in the UK.
