This chapter critically examines the concept of “citizenship” through the lens of precarity, particularly in the context of migrant workers in Italy, Germany, and the UK. It highlights the exclusionary nature of citizenship as constructed within nation-state frameworks, emphasising how specific categories of individuals—such as asylum seekers, expats, undocumented migrants, and even EU citizens—are classified differently and face varied degrees of vulnerability. Drawing on recent migration and border studies, the authors argue that all mobile individuals, to differing degrees, encounter shared experiences of precarity, regardless of their legal status. Through detailed case studies in Germany, Italy, and the UK, the chapter explores the intersections of mobility, socio-economic marginalisation, and processes of racialisation, revealing how bordering practices shape the lived realities of these individuals. Ultimately, the analysis aims to deconstruct binary oppositions such as citizens/non-citizens and to illuminate the complexities of (non)citizenship, highlighting the common vulnerabilities experienced by precarious workers across national and legal boundaries.
