Is he working for a private contracting company? How long has he worked for them?
Can he collect unemployment? Is he covered for health insurance through this employment, because sometimes if that is the case he may be layed off to lower health insurance rates or maybe liability rates. Has he taken time off for his issues? If not then there may be grounds for some kind of predudice.

As far as the holidays coming, don't let that get you down, remember at least you have money coming in to pay the necessities, many have nothing, count some of your blessings. Was the work very taxing work? It does sound fishy to me because they hired him knowing his disabilities and now they are using that for an excuse to let him go. Okay they are firing him? and not laying him off? He needs a reason in writing.
