GM Workers at Mexican Plant to Vote on New Union in Wage Push

Workers in General Motors Co.’s plant in San Luis Potosí in central Mexico will vote this week on joining a new union that is free of government and management influence, as independent unions in Mexico’s auto industry gain traction.

The 6,500-strong workforce at the GM plant has been without representation since 2023 after the former union failed to meet certification requirements under the North American trade deal USMCA and was replaced by an internal workers council run by GM.
