United States Seeks Mexico’s Review of Alleged Denial of Workers’ Rights at Newmont Minera Peñasquito, S.A. de C.V.

WASHINGTON - The United States has invoked the Rapid Response Labor Mechanism (RRM) in the United States-Mexico-Canada Agreement (USMCA) to review whether workers at Newmont Corporation's Minera Peñasquito, S.A de C.V. (Newmont Peñasquito), located in the state of Zacatecas, Mexico, are being denied the right to freedom of association and collective bargaining. The United States has suspended liquidation of unliquidated entries of goods into this country from the Newmont Peñasquito facility, which produces gold, silver, lead, and zinc. The facility also imports auto parts into the United States.

Today's action demonstrates the Trump administration's America First approach, which ensures our trade partners do not undermine worker protections to gain an unfair trade advantage or attract investment.

The Secretary of Labor and the United States Trade Representative co-chair the Interagency Labor Committee for Monitoring and Enforcement (ILC). On May 13, 2026, the ILC received an RRM petition from the Sindicato Nacional de Trabajadores Mineros, Metalúrgicos, Siderúrgicos y Similares de la República Mexicana (Los Mineros), a Mexican labor union. The petition alleges that Newmont Peñasquito has violated workers' rights by retaliating against workers for engaging in union activity, including through unlawful dismissals. The ILC reviews RRM petitions that it receives, and the accompanying information, within 30 days.

After conducting this review, the ILC determined that there is sufficient, credible evidence of a denial of rights enabling the good faith invocation of enforcement mechanisms. As a result, the United States Trade Representative has submitted a request to Mexico that Mexico review whether workers at Newmont Peñasquito are being denied the right to freedom of association and collective bargaining. Mexico has 10 days to agree to conduct a review and, if it agrees, 45 days from today to complete the review.

The RRM, developed under the first Trump administration, is an unprecedented trade tool that works to level the playing field for American workers and businesses by addressing weak labor law enforcement in Mexican workplaces that compete in trade with the United States.
