In a move likely to disrupt holiday deliveries, the Teamsters union is launching the largest strike against Amazon in U.S. history. Thousands of Amazon workers across the country left the job at 6:00 am Thursday, accusing the company of refusing to bargain with their newly formed union.  

"If your holiday package is delayed, you can blame Amazon's greed," said Teamsters General President Sean M. O'Brien. "We gave them a clear deadline to negotiate a fair contract, but they chose to ignore it."  

The strike involves workers at Amazon fulfillment centers in New York City, Atlanta, Southern California, San Francisco, and Skokie, Illinois. Teamsters officials say workers at other facilities may join the walkout in solidarity.  

The Teamsters represent nearly 10,000 Amazon workers who voted to unionize earlier this year. The union is demanding higher wages, improved benefits, and safer working conditions for its members.  

Amazon has not yet commented on the strike. The company has previously denied accusations of unfair labor practices and maintains that its workers are already well-compensated.

The strike comes at a critical time for Amazon, as the holiday season is its busiest period. It remains unclear how long the strike will last or how significantly it will impact holiday deliveries.
