I think this is the key point. You have a fundamental right to work for anyone who wants to hire you. The government can take away that right (and other fundamental rights) as punishment for a crime when you are convicted. I don't see how they can take away rights that are not a part of that sentence. That would be like calling you back for another year of prison after your sentence was completed.
