An independent union’s victory for the right to represent workers at General Motors Co.’s truck plant in Mexico has the potential to spark growth for the nation’s long-stagnant wages. 

The workers who build Chevrolet Silverado and GMC Sierra models in Silao picked the independent group, SINTTIA, to represent them by a wide margin, Mexican labor authorities said. In doing so, the 6,000 workers spurned CTM, Mexico’s entrenched labor organization, and other competing groups.
