Union workers went on strike at seven Amazon fulfillment centers in Southern California and several other U.S. cities on Dec. 19 as attempts to reach a labor agreement with the mega online marketplace stalled, according to the Teamsters organization.
Amazon’s warehouse and logistics workers officially organized and became affiliated with the 1.3 million-member International Brotherhood of Teamsters in June, according to the union, and efforts to produce a bargaining agreement with the company have failed.
