"With this book Keith Mann carries forward a vital tradition of North American labor history inspired by the work of Charles and Louise Tilly. Constructed around the dialectics of skill, technological change, and the organization of the labor process in Lyon's two key industries, while grounded in the distinctiveness of a particular spatial community shaped dynamically through time, it casts the politics of the Popular Front era in a strikingly original light." · Geoff Eley, University of Michigan "This is an important book of exceptionally-high academic quality. With great skill, Mann documents and analyzes the influence of technology and work organization on the character of labor militancy. This book notably advances our understanding of these issues." · Michael Hanagan, Vassar College "Keith Mann has written an important book that should be read not only by historians and social scientists but by all interested in movements for social change." · Gerald Friedman, University of Massachusetts Amherst Escaping the traditional focus on Paris, the author examines the divergent political identities of two occupational groups in Lyon, metal and silk workers, who, despite having lived and worked in the same city, developed different patterns of political practices and bore distinct political identities. This book also examines in detail the way that gender relations influenced industrial change, skill, and political identity. Combining empirical data collected in French archives with social science theory and methods, this study argues that political identities were shaped by the intersection of the prevailing political climate with the social relations surrounding work in specific industrial settings.
