Experts Discuss Challenges of Collective Bargaining Amidst Trade Agreements

The review of the trade agreement between Mexico, the United States, and Canada (T-MEC) has already begun, particularly in its labor chapter. Mexico is experiencing a new moment of legal and political redefinition regarding collective bargaining, democratic unionism, and trade compliance, according to experts during a forum titled “Contemporary Labor Reflections.”

Mexico’s Legal Landscape Shift

Carlos Reynoso, former Grupo Bolonia fellow, warned that Mexico is undergoing “a reconfiguration of the role of labor law sources,” where constitutional, legal, international treaty, and collective bargaining norms are no longer operating in a traditional hierarchical manner.

“Today, T-MEC norms are at the center of interpretation and are correcting or displacing historical gaps in domestic legislation,” Reynoso stated. “For the first time, labor non-compliance can translate into immediate trade sanctions, making the exercise or denial of collective rights economically enforceable.”

Asymmetry in the Mexican Model

Darle Rojas, former president of the Conciliation Board, highlighted that this normative shift exposed a historical asymmetry in the Mexican model.

“After legitimization, only around 30,000 contracts survived, meaning more than 100,000 workplaces currently lack a genuine union counterpart to negotiate on their behalf, leaving a representation void that could become a new source of conflict,” Rojas explained.

Impact on Traditional Unions

Pablo Franco, former Grupo Bolonia fellow, emphasized that “the labor mechanism not only corrects abuses but is also dismantling traditional unions and paving the way for genuine negotiations.”

“Companies have preferred to correct issues before facing panels or sanctions,” Franco added. “We are already witnessing an anticipatory renegotiation of the treaty, but businesses are moving to limit the labor mechanism’s scope in the upcoming review. There is an offensive to restrict the rapid response powers under the due process argument. If concessions are made without counterbalance, the risk is a return to simulation.”

Parallel Developments in the United States

Experts agreed that this debate coincides with the United States opening tables to evaluate tariff sanctions and demand broader sanctioning powers for Mexican labor authorities, leading to a recently presented initiative in Congress to grant more authority to the STPS and the Federal Center in cases of employer interference.
