Nearly 10,000 Amazon workers across the U.S. have gone on strike mere days before Christmas. Organised by the International Brotherhood of Teamsters, the union is accusing Amazon of failing to negotiate a fair contract with them. In response, Amazon claims that the workers striking aren't actually its employees.

The action comes over contract negotiations and the company’s refusal to recognize the Teamsters labor union.

Amazon workers are taking part in the largest strike in American history on Thursday, Dec. 19, starting at 6 a.m EST
