WARREN, Mich. — Chrysler LLC said Friday it will make another round of early retirement and buyout offers to factory workers in the Detroit area to reduce the number who are on indefinite layoff due to slumping sales.

Employees will learn about the offers this month, company officials said during an event at a Warren factory where the automaker celebrated the launch of the new Dodge Ram pickup.

It wasn't immediately known how many workers will be eligible. Chrysler has about 45,000 hourly workers worldwide.
