Workers at a Staten Island, New York Amazon warehouse voted on Friday to authorize a strike if the company doesn’t agree to set dates for contract negotiations. The workers are asking Amazon to recognize the union and bargain for safer working conditions and better wages, threatening the possibility of a strike during one of Amazon’s busiest times of the year.

Teamsters general president Sean O’Brien says in a press release that Amazon must agree to bargaining dates by December 15th, which passed yesterday. If Amazon hasn’t agreed, it risks facing a strike by the more than 5,500 workers at its Staten Island (JFK8) fulfillment center. Delivery drivers at a Queens (DBK4) last-mile delivery station also voted to authorize a strike.

“This is my third holiday I’m giving to Amazon,” a worker named James said in a video published Friday by labor nonprofit More Perfect Union. “I haven’t been around for Thanksgiving or Christmas. It’s constant speed-up for the holidays. It’s like twice as dangerous, I would say.”

A newly published US Senate Committee report says that, based on an investigation of Amazon’s records, the company’s warehouse injury rates were “more than 1.8 times that of other companies in each of the past seven years,” according to The New York Times. Senator Bernie Sanders, who chairs the committee, said “Amazon’s executives repeatedly chose to put profits ahead of the health and safety of its workers by ignoring recommendations that would substantially reduce injuries.”

In a statement emailed to The Verge, Amazon spokesperson Eileen Hards accused the Teamsters union of “intentionally” misleading claims that it represents thousands of Amazon employees and drivers.

They don’t, and this is another attempt to push a false narrative. The truth is that the Teamsters have actively threatened, intimidated, and attempted to coerce Amazon employees and third-party drivers to join them, which is illegal and is the subject of multiple pending unfair labor practice charges against the union.

Hards didn’t immediately respond when we asked which charges she was referring to. Conversely, in 2022, the National Labor Relations Board alleged that Amazon itself “repeatedly broke the law by threatening, surveilling, and interrogating” Staten Island workers who were attempting to unionize.

Workers at the Staten Island warehouse voted to unionize in 2022 and joined Teamsters, one of the largest US labor unions, in June, followed by drivers working out of the Queens facility in September. Amazon hasn’t recognized those unions. As of this writing, the Teamsters hasn’t announced an active strike on its X account, its Facebook page, or its site.
