We tend to think about the "gig economy" as a new development - brought into being by Uber and our smartphones. But Louis Hyman shows us the deep roots of casualized and contract labor, tracing the centrality of temps, day laborers, and consultants from the post-World War II years through the present.

Louis Hyman is Associate Professor of History at the ILR School of Cornell University and the Director of the Institute for Workplace Studies in New York City. He is the author of Temp: How American Work, American Business, and the American Dream Became Temporary. He was previously a guest on the first episode of Who Makes Cents.
