I think my t would cringe a bit if I said his job was a calling. He doesn't like to be put on a pedestal. He would probably say it is his profession. He's dedicated to it. He's dedicated to staying up with his education. He's dedicated to his patients.
But a calling? He'd reserve that for religious callings.

By the way, he's never taken a 6 week vacation. In fact, I've never known him to be gone longer than a week. He has good boundaries and knows how to take care of himself. He won't let me abuse my privilges with him. He's a big boy. A strong t knows how to do that.
