Vote counting in the union push at an Amazon warehouse in Bessemer, Alabama, is underway but a winner may not be determined until Friday. By Thursday evening, the count was tilting heavily against the union, with 1,100 workers rejecting it and 463 voting in favor. The count will resume Friday morning. The Retail, Wholesale and Department Store Union, which is organizing the Bessemer workers, said that 3,215 votes were sent in — about 55% of the nearly 6,000 workers who were eligible to vote. The union said hundreds of those votes were contested, mostly by Amazon, for various reasons such as the voter didn’t work there or doesn’t qualify to vote. The union would not specify how many votes were being contested.
