That waiver sounds awfully broad to me. It also sounds like a canned waiver that is used on lots of forms. It's a "CYA" move on the part of the t. Just a guess but the employer part at the beginning might be in there for disability purposes or taking extended time off from work. Some employers require doctor's notes when people use "sick" days or request a medical leave of absence. I would ask the t to go through the statement with you and explain why each section is in there. If she won't do that, find someone else. You have a right to know what you are signing and why.
