Labor strife over a proposed wage cut and subcontracting flashed at two General Motors Co. plants in the past two weeks.
At GM's Indianapolis stamping plant last week, UAW workers rejected a 50 percent pay cut proposed by a potential buyer, ending hopes that the plant would stay open.
GM spokeswoman Kim Carpenter said GM has begun winding down the plant, and it will be closed by December 2011.
Gregory Clark, shop chairman for UAW Local 23, said the plant's 650 hourly workers hope to transfer to other GM jobs or retire.
One-third are eligible to retire, he said.
Meanwhile, the Lordstown assembly plant in Ohio, where the critical new Chevrolet Cruze compact is being built, was the scene of another dust-up.
Late last month, after learning GM had sent Cruzes off-site to a vendor for factory repairs, local UAW leaders at Lordstown published an insult-laced flier accusing GM of violating contract provisions that require such work to be performed in-house.
Factory repairs are made on vehicles after they leave the assembly line.
In the flier, UAW Local President Jim Graham and shop chairman Ben Strickland said management showed workers no respect and had been "sneaky, evasive and dishonest."
Reached last week, Graham backed off his remarks, saying the issue was a "family squabble" that had inflated under the pressure of launching the Cruze.
The compact is just reaching dealerships.
Graham said GM no longer is taking the underbody repairs outside the factory.
Company spokesman Chris Lee said last week that GM is resolving the issue with the UAW.
