They don't even ask about it for your employee physical exam? Here in MD they absolutely do and even have a list of ailments like HTN, diabetes etc. MS wasn't on that list but it clearly said to add any other chronic health condition or disease and that failing to disclose is grounds for termination.

Again I wouldn't even take a health exam until I had the offer in writing and surely wouldn't advise disclosing to a supervisor if MS isn't apparent. No matter what they say I don't believe any company is actively seeking out disabled employees unless maybe its someone with a disibility like hearing or vision where it isn't going to necessarily cost them money or be likely to get worse. Just my two cents though and everyone needs to do whatever is best for their situation.
