🗞️ Guns, Gold and a Union Fight: How a Mexican Mine Became a Test Case for North American Labor Law
A USMCA trade panel ruled that Orla Mining's Camino Rojo gold mine in Mexico used narco-linked intimidation to oust workers' union. The U.S. won its second-ever Rapid Response Labor Mechanism case, with implications for critical mineral supply chains.
Deep in the mining state of Zacatecas, workers at the Camino Rojo gold and silver mine say armed strangers began showing up. At union meetings, men with guns interrupted the proceedings. At workers' homes, visitors delivered a message: leave your union, or face the consequences.
The result, according to a trade panel ruling made public on March 26, 2026, was a "severe" violation of Mexican labor law and the United States-Mexico-Canada Agreement. The panel found that Camino Rojo, the mine's operating company and a subsidiary of Vancouver-based Orla Mining Ltd., was the "main promoter" of a coordinated campaign to strip workers of their right to organize freely, in part by facilitating the involvement of a known narcotrafficker.
The dispute began in June 2024, when Los Mineros, formally the Sindicato Nacional de Trabajadores Mineros, Metalúrgicos, Siderúrgicos y Similares, filed a petition with the U.S. Department of Labor. The union alleged that Camino Rojo had worked to dismantle its representation and install a company-preferred union, the Minas Union, affiliated with the Federación Nacional de Sindicatos Independientes. Workers reported disinformation campaigns, pressure to sign documents changing their union affiliation, and coerced attendance at meetings intended to engineer a switch in representation.
Mexico conducted its own review and found limited evidence of employer interference, but declined to investigate the violence, citing jurisdictional constraints. Unable to agree with the U.S. on a remediation plan, Washington formally requested a dispute settlement panel in December 2024 under the USMCA's Rapid Response Labor Mechanism, a trade enforcement tool that allows the U.S. to impose penalties on specific Mexican facilities found to be violating workers' associational rights. After on-site verification visits and hearings in Mexico City in late 2025, the panel issued a final determination in favor of the United States, only the second such panel victory under the mechanism and the second successful labor ruling under any U.S. free trade agreement.
The RRM was embedded in the USMCA, which was negotiated under the first Trump administration and enacted with broad bipartisan congressional support in 2019 and 2020. The mechanism was included at the insistence of House Democrats as a condition of passage and has since been used by both the Biden and Trump administrations to pursue labor violations at facilities across Mexico.
The Camino Rojo case carries weight well beyond a single labor dispute. Gold and silver are the primary outputs of the mine's open-pit operation, and gold and zinc found in the deposit's deeper sulphide zones are among the minerals the U.S. government has designated as critical to national security. That framing has added a supply chain dimension to what might otherwise have been a more narrowly drawn enforcement matter. The case also drew international attention. Canadian steelworkers joined Mexican miners in protests outside Orla Mining's Vancouver offices in June 2025, and Canada filed its own separate USMCA complaint, only the second time it has invoked the mechanism.
The panel's determination is final. What penalties, if any, will be imposed on the facility remains subject to further negotiations between the United States and Mexico.
Key Points
- A USMCA Rapid Response Mechanism panel found a "severe" denial of labor rights at the Camino Rojo mine, owned by Canada-based Orla Mining Ltd., in Zacatecas, Mexico.
- The panel identified the mine operator as the "main promoter" of the violations, which included facilitating the involvement of a known narcotrafficker to intimidate workers.
- Armed individuals disrupted union meetings, issued death threats, and visited workers' homes to coerce them into switching union affiliation.
- Mexico's own review found only limited evidence of interference and declined to investigate the violence, citing jurisdictional limits. The U.S. and Mexico could not agree on a remediation plan, prompting the panel request.
- This is only the second U.S. panel win under the USMCA Rapid Response Mechanism and the second successful labor ruling under any U.S. free trade agreement dispute process.
- The RRM allows the U.S. to suspend customs liquidation on goods from a non-compliant facility and, in more severe cases, deny preferential tariff access entirely.
- Gold and zinc from the deposit are designated critical minerals under U.S. policy, linking the case to broader national security and supply chain concerns.
- Canada filed its own USMCA complaint over the matter, only the second time it has used the mechanism.
