A propsectivist anthropology should be concerned first of all with a kind of 'urgent anthropology' that consists of understanding the social forms into which we may be about to move. Nash and Hopkins 1976 These co-authored words of feminist anthropologist June Nash are a fitting coda for this set of ethnographic articles on labor unions of miners in Zambia and Democratic Republic of Congo, maquila and agricultural workers on the U.S.-Mexico border, steelworkers in Argentina, and ship workers in Greece. June Nash was a pioneer in the anthropology of unions. She saw them embedded in community life and as agents of social and political change. She understood that unionsmembership in them, identification with them, and the subjectivities they make-combine local social structures, rituals, and belief systems with ideologies, organizational structures, and political aspiration that are authored in national and international arenas. She mapped how unions are connected to uneven capitalist accumulation at a world scale, whether that manifests as the reimposition of colonial capitalist extraction after the 1964 coup in Bolivia or deindustrialization in a New England U.S. city in the 1980s. Nash was a dedicated fieldworker, and she wrote eloquently about what unions meant to her informants. She dealt in affect, social relations, and politics, and she had her eye on labor and capital at local and global scales. I offer comments on this special issue as a tribute to June Nash who died in the last weeks of 2019 at the age of 93. We would not have such a developed anthropology of unions today without her foundational scholarship. Her legacy should remind us of the importance of both close ethnography and world historical anthropology for understating the role of unions in the contemporary moment. The epigraph is taken from Nash's co-edited Popular Participation in Social Change: Cooperatives, Collectives, and Nationalized Industry (Nash and Hopkins 1976). Her own contribution was a chapter on workers' control in Bolivia during the Revolutionary Nationalist
