GM to lay off about 4,000 salaried workers: source

General Motors is expected to lay off about 4,000 salaried workers under a reorganization announced late last year, a person familiar with the matter said Friday. The layoffs are part of a cost-cutting plan GM announced in November, which will slash 15 percent of its salaried and contract staff and shutter seven plants, including five in North America. Media reports estimated the total job cuts of salaried staff and union workers at about 14,000, including about 6,000 union workers.
