Fifty-three-year-old August Costa, of Ohio Township, says he was harassed from 2005 to 2007 when he complained to Ed Trees, then executive director of the lottery.
Costa claims the supervisor then retaliated by reprimanding him for various reason until he was finally fired on Aug. 16, 2010 on what he contends is an unfounded allegation of falsifying work records.
A spokeswoman for the lottery declined comment on the lawsuit.
Costa's attorney declined to release additional details.
