DETROIT (AP) — Chrysler LLC says it will cut 1,000 salaried jobs worldwide by Sept. 30.

The automaker announced the cuts Wednesday in a letter to employees.

Chrysler says the layoffs are needed because of the prolonged slump in the U.S. auto industry.

Chrysler spokesman David Elshoff says the company hopes most of the cuts will be accomplished through early retirements, attrition and voluntary separation programs. But he says involuntary layoffs will be considered if the company fails to meet its targets.
