With less than ten days until the legal deadline, labour tensions at the General Motors (GM) plant are reaching a critical point. This Tuesday, union representatives from the National Independent Union of Automotive Industry Workers (SINTTIA) and company executives will resume negotiations to try to resolve the impasse in the Collective Bargaining Agreement (CBA) review. However, the rank-and-file workers have already begun formally forming their strike committee.

Despite the openness to dialogue, 300 workers formally joined the strike committee at an assembly. This body will be responsible for coordinating logistics, security details, and operational strategy should the red and black flags be raised on March 25.

For a plant that employs 7,000 workers, the mobilization of this committee of 300 delegates sends a clear message to the company: the willingness to reach an agreement does not imply a renunciation of their labour demands.

SINNTIA was among the first Mexican unions to secure the right to negotiate the Collective Bargaining Agreement after the implementation of the 2019 labour reform.

This process is not just another contract review, as this union is one of the emblematic organizations of the new labour era in Mexico. It’s worth remembering that this union was among the first to secure the right to negotiate the Collective Bargaining Agreement after the implementation of the 2019 labor reform, breaking with decades of traditional practices and legitimizing its representation through free, direct, and secret ballot.

The next few hours will be crucial. While the company seeks to maintain operational competitiveness, the union is pushing for salary increases and benefits that compensate for the current cost of living.
