With a tentative deal with General Motors still to be ratified, the United Auto Workers remain on strike. And it's not just the plants at which UAW's unionized laborers are striking that are affected, either.

According to the Detroit Free Press, production of the new Chevy Blazer has been halted due to the strike, despite the vehicle being manufactured south of the border in Mexico, beyond the ostensible reach of the UAW. "Production of the Blazer will be down until the strike is done," GM spokesperson Dan Flores confirmed to the Freep.

The decision to build models like the Blazer in Mexico has been something of a sore point for the UAW and its members, who would rather see these vehicles being produced by its unionized laborers in the United States and Canada. But if the Blazer is made in Mexico beyond the union's reach, why is it affected by the strike, you wonder?

The answer comes down to parts. Though final assembly takes place south of the border, the Blazer (like most of GM's other models) replies on components coming in from factories in America – factories where UAW members usually work and are now on strike.

The Blazer isn't the only vehicle that GM assembles in Mexico. Along with additional production in the Canadian province of Ontario, GM also also makes the Chevy Equinox at the San Luis Potosi plant, alongside the Trax and GMC Terrain. However not all those models are on hiatus pending resolution of the strike. Flores confirmed that production of the Equinox is running normally at Mexico and Canada plants."

GM and the UAW reached a tentative agreement last week that stands to put some 50,000 laborers back to work at 55 factories across the United States. The union has another five days to ratify the deal, and remains on strike until then.
