Amazon warehouse workers here were voting overwhelmingly against forming a union Thursday after a monthslong campaign in which labor had hoped to make inroads into the sprawling company. As vote-tallying paused for the night, 1,100 employees had voted against unionizing, compared to 463 in favor. The tally presented a nearly insurmountable climb for union supporters to obtain the 1,608 votes needed to win... While the vote has not been completed, the Retail, Wholesale and Department Store Union, or RWDSU, the union seeking to represent the 5,800 workers in Bessemer, has already said it would challenge the vote by filing unfair labor practice charges with the NLRB. It will allege that Amazon broke the law with some of its anti-union activity in the run-up to the election. "Our system is broken, Amazon took full advantage of that, and we will be calling on the labor board to hold Amazon accountable for its illegal and egregious behavior during the campaign," said Stuart Appelbaum, president of the RWDSU. "But make no mistake about it: This still represents an important moment for working people, and their voices will be heard."
