Checking e-mail at home

I keep telling myself I need to stop checking my work email when I'm not at work.  Case in point #1, email from the Director of the department last year about a patient complaint, read the email while on vacation.  Case in point #2, email today from the charge nurse who got a phone call saying I don't need to go to court on Monday for a subpoena because the case was pled out.  Obviously this is the first I'm hearing about a court case.  Lets see what professional lawyers are available in my area, it's better to have and not need than to need and not have.  So much for taking a nap at 1pm before shift tonight :(.
