I am still resident, but I would not do it for even 40k/yr if I were an attending.
FM/IM docs have to look it that way: An extra day of work every two weeks at an urgent care or inpatient would get you 40-60k/yr, so why should you put your license in jeopardy supervising someone with dubious training.
Just want to add, you should ask for both (% + Hourly) vs just one or the other, as case in point, what if you need to spend time after hours to go over charts/make changes to management etc. You're losing out if you don't have both components.
Still not work it.. but if you're forced to, you got no other option.
