reports. Employees on Tuesday received letters notifying them of their options.

The company said in February it would eliminate 10,000 of its 73,000 salaried jobs around the world. The automaker also is cutting executive ranks by 34%, the

GM will have 23,500 salaried workers in the U.S., just over half what it had in 2000, when the job cuts are completed.
