Workers at a second General Motors assembly plant in Mexico will vote June 25 to 27 on whether to join SINTTIA (the National Auto Workers Union), the independent union that won a landmark election to represent workers at the company’s Silao plant in 2022.
A win for SINTTIA at the plant, located 90 miles north of Silao in San Luis Potosí, would mark a major breakthrough for Mexico’s labor movement. It would be the first time that an independent union represents two assembly plants at one of the Big Three automakers.
