The more than 18,000 Costco Wholesale (COST) employees represented by the International Brotherhood of Teamsters union voted to authorize a nationwide strike should they not reach a new labor agreement by the end of the month.

"Costco Teamsters nationwide have voted by an overwhelming 85 percent margin to authorize a strike," the union said Sunday. "The vote is a direct result of the company's continued failure to bargain constructively and refusal to present a fair contract offer that reflects the company's record-breaking profits." 

Costco reported profit for its 2024 fiscal year ended Sept. 1 of $7.4 billion, up 17% year-over-year, on revenue of more than $254 billion. Since then, it reported better-than-expected fiscal 2025 澳洲幸运5官方开奖结果体彩网:first-quarter results—its first since 澳洲幸运5官方开奖结果体彩网:higher membership fees went into effect—and posted 澳洲幸运5官方开奖结果体彩网:strong December sales numbers.

"Costco's greedy executives have less than two weeks to do the right thing," Teamsters General President Sean M. O'Brien said. "If they refuse, they'll have no one to blame but themselves when our members go on strike."

Costco did not immediately respond to an Investopedia request for comment.
