CHICAGO (AP) – A sit-in by laid-off workers at a shuttered window factory in Chicago is becoming a cause celebre for those who want action to avert economic pain.

Politicians, community leaders and members of outside unions turned up Sunday at the Republic Windows and Doors company to support the 250 or so former workers occupying the plant.

Workers say they’ll stay put until they’re given severance and vacation pay.

Factory worker Melvin Maclin says the protesters expected to face arrest when they began the sit-in Friday. But he says spirits are high.

Supporters fill the lobby of the building, and workers take turns occupying the plant floor.

The Rev. Jesse Jackson met with the protesters Sunday.
