A Nassau County Public Works employee who won a racial discrimination lawsuit in 2003 is once again suing the county.

Willie Warren received a promotion and job transfer after winning a $150,000 settlement for denial of a promotion based on his color. The case included a tape-recorded phone conversation in which the woman who got the job Warren had applied for referred to him with an ethnic slur. Warren says the racial slurs got worse and seven less qualified white men have been promoted over him since the settlement. He filed a new $100 million lawsuit in federal court Wednesday against Nassau County and the Department of Public Works.

County attorney Lorna Goodman says the new allegations are being taken seriously, but adds that very little of this lawsuit is new. She says the subject of the first complaint was settled and many of the new charges are unfounded.
