In the early 1970s, radio host and oral historian Studs Terkel went around the country, tape recorder in hand, interviewing people about their jobs. The interviews were compiled into a 1974 book called “Working: People Talk About What They Do All Day and How They Feel About What They Do,” which became a bestseller. This week, we’re revisiting two of those conversations. The first is with Gary Bryner, an auto worker and union leader. The second is with Renault Robinson, a police officer. We spoke with both men four decades after their original interviews. These stories originally aired on NPR in 2016.
