WASHINGTON—A U.S. labor complaint under the U.S.-Mexico-Canada trade pact over a General Motors plant union vote in Mexico has been successfully concluded, lifting the threat of U.S. tariffs on the factory’s pickup trucks, the U.S. Trade Representative’s (USTR) office said on Wednesday.
The United States opened the case in May after complaints that workers’ rights at a GM pickup-truck plant in Silao in central Mexico were being violated in a vote on whether to keep or scrap their collective union contract.
