Workers in skilled trades, such as electricians, represented by the United Auto Workers make higher wages than workers on the assembly line because of their special training, Reuters noted.
The buyout, which include early retirements, were offered to workers represented by the UAW at 14 plants, including the Orion Assembly plant in Michigan. That plant in October was named as home to the new Buick Verano compact sedan, which is expected to go into production next summer. Orion will also build a replacement for the Chevrolet Aveo subcompact to be renamed the Sonic.
Monday's announcement comes just weeks after GM, along with crosstown rival Chrysler Group, said it would hire an additional 1,000 engineers and researchers during the next two years to work on electric vehicles.
GM and the UAW will begin negotiations next year aimed at securing a new agreement on wages and benefits to replace an expiring four-year deal.
