DETROIT, Michigan - April 20, 2009 - About 1,600 white-collar workers at General Motors Corp. will lose their jobs in the next few days as the troubled automaker accelerates cost cuts in order to qualify for more government aid.

GM North America President Troy Clarke said Monday in e-mail to employees that the layoffs are needed to ensure the company's long-term viability.

“In these unprecedented times, GM is reinventing every aspect of our business, including our organizational size and structure, to create a lean and agile company,” Clarke wrote in the e-mail obtained by The Associated Press.

Clarke said the next week will be “a very trying time for the entire GM team, but especially for those employees directly impacted by these actions.”

GM is living on $13.4 billion in government loans. The automaker faces a June 1 deadline to cut costs and gain concessions from stakeholders in order to get more government help.

Last month GM began cutting 3,400 U.S. salaried jobs as part of the 47,000 job cuts that it will make worldwide by year's end. Some of the positions will be cut through normal attrition, but most will be through involuntary layoff.

Hardest hit will be the Detroit metropolitan area, especially at GM's downtown headquarters and its sprawling technical center in suburban Warren, where the company does much of its engineering and design work.

The company will be close to its 3,400 goal after the 1,600 layoffs, spokesman Tom Wilkinson said.
