What do human beings do when they work, how is work organized, and what are its economic, social, political, biographical, ecological effects? We cannot answer these questions without drawing on the numerous categories that we use to describe work, such as "skilled" or "unskilled" work, "domestic work" or "wage labor," "gig work" or "platform work." But where do these categories come from, what are their histories, how do they differ between countries, and how are they evolving? Shifting Categories of Work asks these questions, illuminating the many ways in which our societies categorize work.
