Mexico’s independent auto union has bosses scared

Auto executives are well aware of what could be won should Mexico's independent auto union continue its winning streak: there hasn’t been a shared contract at 2 facilities in the Mexican auto industry’s 100-year history, a precedent SINTTIA is determined to break. 

The union made headlines when 6,500 workers voted overwhelmingly to join at GM’s Silao, Guanajuato plant in 2022. On the eve of a union election at a second GM facility, the company is flagrantly favoring a competitor union, SINTTIA says—a union that some allege has ties to organized crime. 

“It’s no use having a little plant with great working conditions and pay,” said Willebaldo Gómez Zuppa, a SINTTIA advisor. “Because ultimately, across the auto sector, all of the other plants are pushing conditions downward.” Improving standards for the long haul will depend on independent unions like SINTTIA building density in the sector as a whole, starting with key players like GM.
