The ADA has lost almost all of its power due to lawyers for companies stripping if of its provisions.
Sad to say. It used to be reasonable accomidations meant that your employer had to meet you half way. No More. Lawyers have worked to get businesses out of having to provide even the simplist accomadations.
Your best bet is to get with a lawyer who specializes in Social Security law and ADA. They may be able to get you some help with your employer.
Sorry I do not have a better picture to paint. But it started out good but has been watered down so much it is almost useless unless your employer wants to comply. If they do not a lawyer is your only option.
