Idk about doctors, because it’s more nurses and other staff that strike. But speaking for nursing, we usually give the employer advanced notice so they can hire travelers (scabs, but also a necessity so you can’t really hate) to work during the strike dates. /Cue the delicious scramble and shitshow lol.

Also sometimes there’s an agreement to provide X number of employees who are allowed to cross the picket line (we want to strike, but not the bad optics of “selfish nurses killing their patients”).
