Workers at seven Amazon facilities are on strike. The union said that the workers are joining the picket line Thursday after Amazon ignored a Sunday deadline the union set for contract negotiations. The workers had authorized strikes in the past few days. It will take place in New York, California, Illinois and Georgia. Amazon says it doesn’t expect an impact on its operations. The Teamsters say they represent nearly 10,000 workers at ten Amazon facilities. Amazon employs 1.5 million people in its warehouses and corporate offices.
