DETROIT, June 1 (Reuters) - Dozens of workers took to picket lines Monday morning at an axle plant in Michigan that supports production of General Motors trucks, some of the Detroit automaker's most popular and profitable vehicles.
On Sunday, the United Auto Workers announced that workers at the plant in Three Rivers, Michigan, owned by Dauch Corp, would walk off the job starting Monday. Dauch, formerly named American Axle, is a major supplier of driveline parts.
GM has about two weeks
of axle inventory on hand to keep building trucks, according to two people familiar with the matter.
GM said it was closely monitoring the situation and "assessing any potential impact."
A Dauch spokesperson called the work stoppage "disappointing" in a statement.
"We remain committed to negotiating with the union in good faith and hope to promptly reach a fair agreement," the spokesperson said.
GM shares were down about 2% in afternoon trading Monday. Dauch's stock price was down about 6%.
The Chevrolet Silverado and GMC Sierra pickup trucks, which are made at factories in the U.S., Canada, and Mexico, are GM's top sellers, accounting for nearly one-third of the company's U.S. vehicle sales.
The UAW is pushing for wage increases after employees made sacrifices to keep the plant open in 2008, according to the union. Top wage earners can make $22 an hour, which is down from as much as $29 an hour in 2008, the union said.
In early May, workers voted 98% in favor of authorizing a strike if needed.
