A conversation with Sarah Bond (University of Iowa) about organized labor groups in the Roman empire. Ancient occupational groups often formed associations (sometimes called collegia) which are often regarded as little more than dining, cult, and burial societies. In her new book, Strike: Labor Unions, and Resistance in the Roman Empire (Yale University Press 2025), Sarah Bond argues that they sometimes engaged in collective action and bargaining. These continued in existence into late antiquity and possibly beyond. Also, check out Sarah's blog History from Below and her contributions to Hyperallergic.
