Background on the Key Players and Relevance

The United States has formally requested Mexico to review labor conditions at Mondelēz Mexico’s plant in Puebla, alleging possible denial of workers’ rights to freedom of association and collective bargaining. This action stems from a November 12 petition by the independent Union General de México (UGM), which accused Mondelēz Mexico and the contractual union of engaging in interference with workers’ attempts to organize independently.

The UGM’s claims, investigated by the Inter-Institutional Labor Committee (ILC), include threats, restricted access to the plant, discriminatory reassignments, terminations, and labor-related suspensions. The ILC, co-chaired by the US Trade Representative and the Secretary of Labor, concluded that there is “sufficient and credible” evidence of labor rights violations after a 30-day review period.

The T-MEC Labor Mechanism and its Implications

The US has activated the T-MEC Labor Compliance Mechanism (MLRR) to address these concerns. This mechanism is a crucial component of the trade agreement’s labor chapter, designed to ensure the effective respect of workers’ rights in specific facilities.

Mexico has 10 days to accept the review, followed by a 45-day investigation period to determine if labor rights have indeed been violated. Should the allegations be confirmed, additional trade measures may follow if corrective actions are not implemented.
