DoYou Tell?

Found this article in the New York Times.

Do you tell your employer about MS ? If Yes when? What was the reaction?
Have you faced discrimination because of MS ?

I told my employer . Ever since, I have been the ping pong ball nobody wants .Well, they still want me but they want , the old me.

Once again I ask. Is it realistic for employers , for anyone, to think we can go a long in a straight line for 30, 40, 50 years and never , ever, break down ? Never have problems ?
