HAMMOND, Ind. (AP) _ Several warehouse workers marched through a northwestern Indiana Wal-Mart store as they protested what they called freezing work conditions.

About 10 workers from the Wal-Mart Consolidation Center in Hammond were joined by about 15 supporters during Tuesday's protest, holding signs saying “We won't freeze for freight.''

Workers told The Times of Munster that the warehouse operated by a Wal-Mart contractor doesn't have heating and that damaged doors allowed wind to enter as wind chills dropped to more than 20 below zero this week.

Leah Fried of Warehouse Workers for Justice says the broken doors allow in rain, snow and wind.

Wal-Mart spokeswoman Dianna Gee says the retailer expects its contractors to provide a safe work environment.
