Four Arab-American employees of a Wilmington, Mass.-based FedEx Corp. facility have filed suit against the company, alleging supervisors repeatedly verbally abused them with a barrage of religious and ethnic slurs and restricted their delivery routes.

In the lawsuit, filed June 29 in Middlesex Superior Court, the FedEx drivers say they were subjected to a “pervasive hostile work environment and have been treated differently and less favorably than non-Arab, non-Muslim drivers in the terms and conditions of their employment.”

In a July 2006 complaint filed with the Massachusetts Commission Against Discrimination, one of the plaintiffs, Loay el-Dagany, said supervisor David Goyette called him a terrorist, threw packages at him and asked if he was planning on sending money to Al Qaeda and Osama bin Laden.

In March, the MCAD ruled that the complaint was valid and the suit could proceed. The lawsuit names Goyette and another supervisor, Michael Melnyk.

The plaintiffs in the case are Dagany, Montaser Foad Harara, Oukhayi Ibrahim and Yasir Sati. Last year, a California jury awarded $61 million to two FedEx drivers of Lebanese descent who said a manager used racial epithets against them. A judge later reduced this amount to $12.5 million.
