U.S. asks Mexico to review a second complaint about labor violations in its auto industry. By The New York Times June 9, 2021, 7:03 p.m. ET The Biden administration is invoking provisions in a new trade agreement to ask Mexico to look into accusations of labor violations at an auto-parts plant near the U.S. border. The action, announced Wednesday by the Labor Department and the Office of the United States Trade Representative, follows a complaint by groups including the A.F.L.-C.I.O., the nation’s largest federation of unions, that workers were being denied the rights of free association and collective bargaining.
