DETROIT -- In its fight for survival on many fronts, General Motors is pushing to save every penny it can, even pressing plant workers to shut off lights, turn off air compressors and lower the heat, according to USA Today.

The drive to pinch pennies came two weeks ago, says David Green, president of United Auto Workers Local 1714 in Lordstown, Ohio, when the plant there was told workers could no longer work overtime.

Workers decided to cancel a bake sale they hold each year for the Toys For Tots program because GM wouldn't let some line workers earn pay while working at the sale as it has done in the past.
