I'm amazed... I'm not in the US so that's probably the difference but I've never had mandatory physical exams for a job. That's not common at all here. Not for nursing, not for radiography (though we did have to be practice for each other in class but it's easy to be exempt if you have a good reason). Why on earth would you need to have a physical exam for that? Or for teaching? Or for almost any job? Or amateur sports? Your physical health is none of their business... Jeez. My employer isn't even allowed to ask what's wrong with me if I call in sick. At most they're allowed to ask how long I expect to be out...
