Thousands of Amazon workers on Thursday launched the largest strike against the retail giant in U.S. history, pressuring the company at the height of the holiday period to follow the law and bargain with those who have organized with the Teamsters union. The strike includes warehouse workers and drivers at seven distribution centers in some of Amazon’s largest markets, including New York, Atlanta and San Francisco; Teamsters have also set up picket lines at many other warehouses nationwide. “We’re engaging in a coordinated action to try to put the pressure on Amazon to stop breaking the law, come to the table,” says Connor Spence, president of Amazon Labor Union-IBT Local 1, which represents workers in New York. “This is an unfair labor practice strike over their refusal to bargain.” We also speak with Ronald Sewell, an Amazon associate in Georgia, who says workplace safety is a major driver of worker discontent, including insufficient access to water and overheating. “The danger is real. It’s not something that we’re making up,” says Sewell.
