What happens when an entire fast-food restaurant staff quits? Today for our special series on “Quitters,” the story of a McDonald’s walkout, and what it can tell us about the labor market right now.Read more: In September, the entire staff of a McDonald’s in Bradford, Pa., walked out and quit their jobs. One of the staff members left a parting note for the customers, written in blue highlighter because he couldn’t find a pen: “Due to lack of pay, we all quit.”“The signs are…kind of like primal screams,” says reporter Greg Jaffe. “It’s [the worker’s] chance to convey a message: We’re being mistreated. We’re tired of it. This corporation treats us badly, and doesn’t care about us.”Today on Post Reports, we’re bringing you the second installment in “Quitters,” a three-part podcast series about a few of the millions of Americans who quit their jobs this year. Jaffe takes us inside the fast-food workers’ season of rebellion.You can listen to the first part of the series here.
