After successfully staging a wildcat strike for higher wages in 2019, many workers at the Tridonex auto-parts plant in the Mexican city of Matamoros, across the border from Texas, set their sights higher: replacing the union that they say failed to fight for them. Six workers at the factory, which refits second-hand car parts for sale in the United States and Canada, told Reuters they felt let down that their union, SITPME, did not back their demands for better pay. About 400 Tridonex workers protested outside a Matamoros labor court last year to be allowed to switch unions.
