Many migrant women in New York City face structural discrimination and administrative hurdles that complicate their access to safe and well-paid labor. Worker cooperatives have been shown to reduce the precarity and economic exclusion of marginalized groups. However, although much is known about worker cooperatives’ economic potential for improving workers’ lives, other social effects remain far less well explored. The present research contributes to exploring this gap by examining how joining a worker cooperative empowers migrant women in their everyday lives. We apply the concept of self-empowerment to several spheres of the everyday lives of migrant women. At an empirical level, the study focuses on migrant women who are members of nine cleaning- or care-worker cooperatives in New York City. The data were gathered using a participatory research approach and consist of interviews, participant observations, and a quantitative survey. The findings are that worker cooperatives have empowering effects on migrant women beyond the sphere of paid work. Although the additional unpaid workload as co-owners of cooperatives represents an extra burden for many migrant women, they now have better wages, more flexibility, and safer workplaces. Furthermore, they acquire a range of leadership skills, enlarge their social network beyond their ethnic communities, and earn increased esteem as co-owners of businesses. Through worker-ownership, migrant women thus increase their economic, cultural, social, and symbolic capital, which enables them to exercise more agency not only in their paid work but also in their families and leisure time.
