Bravo! With modern technology, it is quite possible to be on call 24/7. I refuse. When I am at work, I work. And when I'm not, I am simply unavailable. I teach, so much of my vacation time is pre-determined by the school calendar. Ask me how many school-related emails I have responded to this summer. Answer: Zero. None. We teach people how to treat us based on what we are willing to accept.
