A KQED podcast series on how American workers have lost benefits, power and protections over the last few decades spoke with Urban Planning Professor Chris Tilly, an authority on labor economics. Tilly explained the phenomenon of the “fissured workplace,” where full-time employees work side by side with part-timers, temps, gig workers and contractors. Some classes of workers receive no health coverage, overtime pay, worker’s compensation or other protections, increasing company profits while breaking up worker solidarity. Tilly described a job he held in the late 1970s at a hospital that directly employed not just health-care professionals, but cafeteria staff, custodians and maintenance workers. Now, such positions would be outsourced at many companies, a trend that emerged not from new laws or regulations but from “an experimentation process,” he said. By testing existing legal boundaries, Tilly said, managers and executives discovered that “we could get away with this, there’s nothing stopping us from doing this.” Tilly’s segment begins at minute 23:35.
