Framed so simply -- "should physicians be 'allowed' to strike?" -- then the answer to the question must be yes.
A walkout could well be justified, if physicians are not given a safe work environment, if verbal and physical abuse are heaped upon the physicians, if the workplace is operated in a racist manner, if physicians are not allowed breaks for meals or bathroom, etc. etc.
If you say no to the question, then that seems to say physicians, unlike all other workers, must endure any and all abusive conditions, no matter what. That seems unfair, and ultimately not good for patients, as physicians will not perform efficiently in an intolerably hostile work environment. I would think the question would be followed by further questions attempting to find the tipping point between more trivial physician concerns, and more certain patient harm resulting from a strike. That would be interesting to discuss, but I would say you would have to start by acknowledging doctors are humans, who have the right to flee oppression and abuse just like all other humans.
