This month we celebrate the labor movement and the contributions that laborers have made to achievements of the country. In honor of Labor Day, we've gathered together episodes from the archive that focus on questions about work and workers. What exactly is work in the first place? What causes workers to become alienated from their labor? Do we procrastinate to avoid doing work? Will increasing automation mean that future humans need labor no more? And does retirement mean the end of work or just a change in work?
