WHERE CAN I GET A LAWYER FOR DISCRIMINATION AGAINST THE DISABLED?

My husband is a registered disabled citizen (blind) and has held his job for 11 years. Due to company downsizing, he was placed back in a job that he was removed from due to his blindness. When he asked his bosses why they placed him back in a job that they knew he could not do due to his visual impairment, they said he would just have to earn his way out of it and into another job. I think this is obviously a violation of his disability rights and would like to know where to start to fight this battle.
