MONTPELIER, Vt. (AP) — Three former highway maintenance employees are accusing the Vermont Agency of Transportation of mistreating them because they are gay. The Burlington Free Press reports (http://bfpne.ws/1JAp8Wc) the former workers filed the lawsuit Thursday in Vermont Superior Court in Montpelier. Reina Dean, one of the plaintiffs, said in a statement she endured offensive jokes and comments, was denied promotions and given assignments no one else wanted because of her sexual orientation. Dean said she was also groped, grabbed, and bothered by male co-workers, and even propositioned for sex. An agency spokesman and Assistant Attorney General John Dunleavy said they were unaware of the lawsuit.
