(Reuters) - The Teamsters labor union said on Saturday that its negotiating committee has reached a tentative agreement for a new contract with U.S. retailer Costco Wholesale.

"The tentative agreement will be presented to the membership for a vote," the union, which represents more than 18,000 workers at Costco, said in a post on X, without providing any details about the agreement.
