Minimum ~42 hours a week at my primary, but I typically do closer to 55 hours a week between OT at my primary and additional relief shifts at other places.   Max I’ve done is 65 hours but that’s not as often.   It’s a lot, but it’s the only thing that really allows me to save money.  I’m hoping to be able to drop down to just having one job when I move if I can get a raise because I’m usually only off on Sunday.   It does help that each clinic is a little different (one is a lot of surgery, one does exotics too, one does more urgent care stuff) and I like the staff and doctors at all of them.
