Chrysler LLC said Thursday it would keep three of its plants shuttered for an additional week, as workers at nearly two dozen plants prepare to return to work.

The Auburn-Hill, Mich.-based automaker said in a statement that it notified workers at the Belvidere Assembly Plant in Illinois, the Sterling Heights plant Michigan, and its Toluca, Mexico assembly plants that they would return to work on Jan. 26, a week later than originally intended.

In December, Chrysler said that it would close all 30 of its manufacturing plants for a month in an effort to adjust production to slowing vehicle demand and conserve cash.

Workers at 23 Chrysler plant will return to their jobs on Jan. 20. Workers at the company's Toledo North Assembly Plant and Supplier Park in Ohio will be back on the job Jan. 26, as previously announced. Workers at the Windsor, Ontario, plant and Conner Avenue Assembly Plant in Detroit will return Feb. 2, as previously scheduled.
