This article examines how precarious migrant workers build solidarity through multiple identifications beyond traditional class-based understandings. Based on interviews with 113 participants across three sectors in Denmark, we explore how migrant workers’ solidarity is shaped by both internal group dynamics and external boundary making. We identify two key forces affecting worker solidarity: ‘solidarity with’, where workers prioritise personal and familial identities over class; and ‘solidarity against’, marked by employer dependency and unclear boundaries against external entities. Our findings demonstrate that migrants’ identifications emerge through multifaceted processes in transnational settings, influenced by family obligations, survival strategies and structural dependencies. This understanding advances contemporary debates on migration, solidarity, class identification and collective action.
