Amazon beat back a push to unionize in its Bessemer, Alabama fulfillment center thanks to a surprisingly one-sided vote — nearly two-thirds of the facility’s workers chose not to join the Retail, Wholesale and Department Store Union on April 9th. According to a list of objections filed with the National Labor Relations Board late Friday, however, the union argues Amazon won the vote because it “interfered” with the rights of its employees “to vote in a free and fair election; a right protected under Section 7 of the National Labor Relations Act.”
