This article explores migrant workers’ identifications and problematises the concept of solidarity. Based on ethnographic research among migrant workers, we show how migrants primarily build collective identities based on gender, family, and survivalism rather than class. This lack of class-based solidarity complicates the emergence of a collective workers ‘we’. We identify two parallel and related dynamics shaping worker solidarity which we utilize though a conceptual framework that differentiates between ‘solidarity with’ and ‘solidarity against’: Internal group formation, where workers prioritise personal and familial identities over class, crucial for internal solidarity and in-group maintenance; and external group formation, marked by a lack of clear boundaries against external entities and employer dependency, disrupting collective worker unity. We posit that class-based identifications are not merely class-based but a multifaceted identification process of developing solidaric ties with or against in multiple transnational settings.
