This week we look back on some of our favorite stories from a year that had us asking—sometimes with excitement and sometimes with exasperation—"What Next”? This episode originally aired April 4.   Few were betting that a group of workers on Staten Island could win union recognition at their Amazon warehouse. Now that they’ve done it, can they replicate this win at other shops across the country? And what will the nation’s largest unions do to help Amazon workers join the labor movement?   Guest: Steven Greenhouse, senior fellow at the Century Foundation and author of Beaten Down, Worked Up: The Past, Present, and Future of American Labor.   If you enjoy this show, please consider signing up for Slate Plus.
