My wife has MS and is going on disability. No one seems willing to take her case and I'd like to find out why.

Without knowing the individual facts of your case it is impossible to render much sage advice. However, disability discrimination cases are difficult for plaintiffs to win in the Northern District of Georgia, and in the 11th Circuit especially. This is the reason very few attorneys want to take these cases: There is too little assurance that the attorney will ever get a pay day at the end of the long and expensive litigation process. (I'm sure you wouldn't want to work without getting paid either.) If the employer is covered by the ADA or Rehabilitation Act, as amended by the ADAAA (i.e., the employer has at least 15 employees), and if your wife's condition would qualify her as disabled within the meaning of that law, the employer has a duty, upon request,  to make reasonable accommodations to the disability.  That might involve shceduling or other accommodations. The employer is not required to give the disabled person the accommodation she desires if there is another accomodation that would enable the employee to perform the essential functions of the job.
