Oct. 29 (UPI) -- Automaker General Motors laid off 3,300 workers at manufacturing plants in Michigan, Ohio and Tennessee amid changes in the nation's electric vehicle market.

The layoffs affect 1,200 workers at GM's electric vehicle manufacturing plant in Detroit and 550 at the Ultium Cells battery plant in Ohio, CNBC reported on Wednesday.

Also laid off are 850 workers at the Ohio Ultium Cells plant, plus another 700 in Tennessee, but those layoffs are temporary.

GM officials attributed the layoffs to market conditions for electric vehicles.
