Amazon workers would unionize under the RWDSU.However, the decision is not final. The hearing officer's recommendation will now be sent to the NLRB's Region 10 regional director, Alabama.The NLRB will issue an Order to Ascertain the Results of the Original Election, in which Amazon employees voted 1,798 against 738 for unionizing. 505 ballots will be challenged and 76 void."We heard clear evidence that Amazon attempted to illegally interfere and intimidate workers who were trying to exercise their rights to form a union during the NLRB hearing. The RWDSU president Stuart Appelbaum stated in the statement that he supports the recommendation of the hearing officer to have the election results rescheduled and a new election conducted."As President Biden reminded me earlier this year," the decision of whether or not to form a union should be decided by workers and not employers. Amazon's conduct during the election process was abominable. Amazon cheated and were caught. They are now being held responsible.Amazon did not respond immediately to a request for comment.After the initial election period in which Amazon aggressively campaigned against unions, the RWDSU filed 23 formal oppositions to Amazon's conduct. It accused it of violating labor law by interfering in the voting process and trying pressure workers to vote against forming unions.One of the major objections to the union revolved around a mailbox Amazon executives pushed the USPS into installing outside its warehouse. This raised concerns that the mailbox could be seen as an attempt to discourage workers from voting for a union.Amazon denied these allegations and previously told Insider that it "rather than accepting the choice of these employees, the union seems determined continue misrepresenting facts in order to drive their own agenda."
