UAW Statement on Mexico’s SINTTIA Organizing Drive at GM San Luis Potosí

The right to have a voice on the job—to shape your future, your working conditions, and your livelihood—is a basic human right. That right includes the freedom to form and join a union, free from coercion or interference. The UAW stands in solidarity with SINTTIA and the workers at General Motors’ San Luis Potosí plant as they exercise that fundamental right.

We applaud SINTTIA’s official filing to represent GM employees in San Luis Potosí, validated by the Federal Center for Conciliation and Labor Registry. Since the previous union failed to legitimize its contract under Mexico’s 2019 labor reform, this plant has been without union representation. SINTTIA’s leadership offers a real opportunity to restore democratic representation and win meaningful improvements for autoworkers.

SINTTIA’s record in Silao—where it won double-digit raises and inspired gains across GM Mexico—shows the power of independent unionism. But that power is now under threat. We are alarmed by credible reports of GM management colluding with a protection union to block SINTTIA, including misuse of personal data and illegal on-the-job campaigning.

These violations of labor rights and USMCA trade rules must not stand. The UAW calls on all allies to support SINTTIA and defend the workers’ right to choose.
