The International Brotherhood of Teamsters said unionized workers at facilities in New York City; Skokie, Illinois; Atlanta, San Francisco and southern California will join the picket line to seek contracts guaranteeing better wages and work conditions.
The Teamsters union has said it represents about 10,000 workers at 10 of the company's US facilities, representing about 1 percent of Amazon's hourly workforce. Among them, seven will walk out on Thursday, the Teamsters said.
