> It got into ridiculous situations where a friend who is an urology doctor was on paid leave for last few weeks, simply no work for them under these rules. Another friend, radiologist in a hospital heavily hit by covid, worked only 4 hours/day shifts, instead of usual 10-12 ones.

I'm assuming specialists ain't allowed to work as generalists, then? I'd imagine that specialized doctors (like urologists) should be able to double as PCPs should the need arise (like, you know, a global pandemic). I ain't a doctor, though, so I'm perfectly willing to accept "specialist and generalist practice are too different from one another" as the answer here.
