The charges were filed with the U.S. Equal Employment Opportunity Commission.
The workers say the DB Schenker Company has created a hostile work environment by not removing graffiti from walls and allowing confederate flags near the warehouse entrance.
"There's KKK signs written in the bathroom, swastikas on the coffee machine and on the walls of the bathroom. We brought it to management. We asked them to come to our daily shift meeting. Our supervisors tell us that they won't come in and talk to us," said Angela McDonald, warehouse worker.
Schenker Logistics, Inc. sent the following statement to ABC7 on Friday:
"Schenker Logistics, Inc. is committed to maintaining a workplace free of discrimination and harassment. We just became aware of these disturbing allegations late yesterday. We will immediately conduct a thorough and complete investigation, and if any of the claims have merit, we will take such remedial action as is warranted to correct the situation."
