General Motors Co. will announce increased hours at several factories due to rising sales from the government's Cash for Clunkers program.
Union officials say GM will increase production at its Lordstown, Ohio, and Orion Township, Mich., factories.
One day will be added to the work week at the Lordstown plant, which makes the Chevrolet Cobalt small car. Increases also are expected at the Orion plant, where the Chevrolet Malibu and Pontiac G6 are made.
The clunkers program offers up to $4,500 to people who trade older, inefficient vehicles for new, more efficient models.
Ford Motor, Honda, Toyota, Hyundai and Chrysler all have announced production increases due to the program.
