Awwww, c'mon
How many of us have an "I read your e-mail" t-shirt in the closet somewhere. I am fully up with the "need to know" restrictions, I have them in my job, but I am paid a lot more than some clerical worker. And it's not about the money, if part of your job is to read and review medical files, and you read them all, because you are bored, I would just say you are being proactive.
granted I don't wear my "I am root, fear me" or my "I read your e-mail" shirts much anymore, but still, chill.
