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.
