I dunno man....these days it would take a lot for me to work an extra shift in a dysfunctional place. Prob $500 / hr? Even that prob not enough, unless they're willing to waive the whole BS credentialing process. Credentialing really is the rate limiting step for me to do any kind of PRN / locums work anywhere else.
Personally I found doing locums (really more... per diem work...) 1-2 shifts a month somewhere I could drive to in 30-60min from my house, even if slightly dysfunctional, was fine for my psyche. In a way it was a little refreshing.
I found it refreshing to have a DIFFERENT dysfunction. Like "oh yeah the hospitalists here are persnickity about admissions" but "holy **** the lab here gets stuff done quick, and there is a Popeye's a mile away for my drive home!"
It was a little fun to do different locations / patient populations (free standing rural, large academic referral center, busy community in a different town than normal).
In fact, the shift to entirely hourly pay was fun for these type of adventures, b/c I would just be dumb and friendly and tell the charge I was there to work, see whomever got brought back, tell me what to do and I'm happy. WR has 45 bc they have rooms shut, and you don't want me to put WR orders by policy? OK I'll sit and wait. WR exploding and you want to pay me to play PIT doc with a tech for 4 hours. Sure thing! Other docs don't want to see septicons from nursing homes bc they take a long time? I'll see 5 of those cool. Other docs don't want to work with the PA (whom presents everything to you, and you get to go see their patient yourself, no rush)... I'll chill with the PA! I just did my best impression of a golden retriever, turned off the half of my brain that tries to fix all system problems and improve operational flow, and took good care of every individual they brought to me.
The key was being able to separate from the complex operational issues at some of the hospitals, which in my main job I would have been running in circles trying to fix. Not my role as a per diem. It was almost like taking a working vacation day twice a month! Also the actual MD/PA culture at each of these shops was pretty solid, and people took/gave good signout, etc.
BUT, huge caveat here... these places had at worst mild/moderate dysfunctions. They were not literally melting to the ground with people coding in the WR constantly. During the covid surges where ICU capacity was nil, they had significant ICU boarding problems, but so did every ED in the state/region.
The pay was just on par with my day job, so when these dried up I didn't push hard looking for more... I worked too much the first 2 years of the pandemic.
So if one of these type of things popped up again? Yeah I might do it once a month. Depends on the details. I'm pretty crispy and I'm not really looking for more clinical work, but I could trade one shift at home for one away for variety, etc.
But at this point, you want me to go work in a truly dysfunction hellscape, a medicolegal quagmire of death? The hourly rate I would ask for would be more than double my "normal" rate, probably triple to actually get me to consider. Yeah at least triple...
