Ok, I hear you. However, I cofounded a medical startup with 3 surgeons, seeing their day to day routine pretty closely, at their offices, at home, etc...
And they definitely worked around their own schedule.
They either owned their own practice, or worked at a larger one, and controlled their own scheduling via their team. Surgeries are scheduled weeks or months in advanced. Only when an emergency came in they needed to shuffle things around - basically the same thing with engineers and planned deployments vs random outages.

Ok, yeah, of course they are not going to just up and leave when there is an appointment or deadline. That has nothing to do with whether or not they chose the time of that appointment in the first place.
