A union representing 18,000 Costco employees nationwide has authorized a strike, signaling a potential work stoppage if negotiations fail. The current contract between Costco and the Teamsters Union expires on January 31st, and 85% of union members voted in favor of the strike action. The union accuses Costco of rejecting proposals and offering counterproposals they describe as insulting,” lacking retirement benefit enhancements and failing to reflect the company’s financial success. Costco is known for positive worker treatment and diversity initiatives. Costco has not yet commented on the matter.
