In a move that may threaten production at General Motors, the United Auto Workers union went on strike against American Axle & Manufacturing Holdings Inc. earlier today. The UAW work stoppage, the third called by the union within the past six months, centered around wages, benefits, and concerns that the company may be moving production to Mexico.

American Axle is the sole axle supplier to GM for light trucks such as the Chevrolet Tahoe and GMC Yukon. The company supplies axles, shafts, and related components to other automakers, as well. As the four-year contract with the UAW neared the end of its term and the strike loomed, American Axle did stockpile its inventory. It is unclear, however, just how much supply is on hand. It may not need to last long, as analysts expect a negotiated settlement to end the strike within several days. This is good news for everyone, especially the workers who are walking the picket lines outside in the freezing snow.
