If you choose to pursue your employer for ADA violations, I recommend an ADA Advocate. We are using The Zunga
https://thezunga.com/. Husband was fired when they decided to harass and treat him as if he had a disability, when he doesnt, also white male in 50's. This gives you protections under the ada even when you are not disabled. Their site is not great but the prepared all legal filings and coached us through everything. We could not have done it alone and theres not much money in it for lawyers
