On Friday, the National Labor Relations Board starts sending unionization ballots to more than 6,000 workers at an Amazon facility in Bessemer, Alabama. Organizers say they want a union so they can negotiate safer working conditions and dispute terminations. Marketplace’s Kimberly Adams speaks with Marketplace senior reporter Meghan McCarty Carino, who covers workplace culture. She said it’s significant that these workers are getting a redo after their union vote last year, which failed.
