@jespah,
I agree - in the US you should be protected from losing your job for health reasons. So I think it would be helpful if you were to tell us where you are living.
I know I filled out a Family Leave Medical form when my daughter was going to have surgery as I would need time off to care for her and here and there time to bring her to appointments for follow up. My current manager was good about it - but it is called CYA (in other words - with all the turmoil at work I didn't want it to hurt me in any way).
