DETROIT -- General Motors may cut more of its workforce by making some of its temporary layoffs permanent.  Between six and seven-thousand workers are currently on layoff, and GM CEO Fritz Henderson says that some of those workers might not be brought back.

Henderson did not say how many of the layoffs would become permanent, but did say that no deep cuts would be made, saying, quote, "I don't think it's necessary."  GM has cut about 13-thousand hourly workers so far this year as part of its court-ordered restructuring.
