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.

Starbucks union's strike will expand through Christmas Eve to a dozen metro areas, while the Teamsters union says workers for Amazon at a California airport have joined other workers protesting.
