STERLING HEIGHTS, Mich. -

Workers at the Chrysler's Sterling Assembly plant have learned they have lost their jobs.

The 1,100 afternoon shift workers were told Thursday their shift was eliminated as part of Chrysler's plan to bring the automaker's production in line with the buyer's demands, a Chrysler spokesman said.

Patrick Walsh, plant manager of the plant, refused to comment.

According to the Macomb Daily, some employees said there were threats written on bathroom doors at the plant to harm unidentified persons.

Sterling Heights police Lt. Michael Reese said they were told the workers would be laid off, but he was unaware of any problems at the plant.

Chrysler has eliminated shifts in Toledo, Ohio; Brampton, Ontario; Belvidere, Ill.; and Jefferson North Assembly Plant in Detroit.

It is unclear if the laid-off workers will be offered an early retirement.
