Job restrictions

Cassidy
So, at my job everyone knows that I'm pregnant, even corporate. Today my regional manager came into work and was wondering why I was moving slow. I said I was bending over trying to figure out product numbers and it was making my stomach hurt. Later on in got a call from my manager saying that I need to have a doctor's note saying what I can and can't do due to my "disability". Not to mention that I need to have it by next weekend. Has anyone else experiencing this where they work at?
