Labor scholars have increasingly recognized the need to look beyond the workplace and explore where and how workers lived, socialized, shopped, or protested. The six books reviewed in this essay contribute to understanding how modern cities shaped the process of working-class formation as well as workers’ identity, experiences, and economic and material conditions. From different standpoints, these urban and labor histories of Paris, Mexico City, Miami, Port Said, Montevideo, and Santiago, Chile, demonstrate the impact of urban modernization, industrial capitalism, and migration on working families. By bringing together books from different regions and historiographical traditions, this essay also reflects on the possibilities and challenges of writing a global labor urban history.
