Not IWBB, but the answer to your question is yes, if you are a member of a group practice then there is more flexibility in work hours and how often you take call.
But the terms of employment contract will spell out exactly what your work hours will be and how often you take night call.
And it will make a difference how large or small the practice group that you join is. And whether it is physician-owned practice group or corporate-owned practice group. You’ll have flexibility in contract negotiations with a physician-owned practice–assuming those still even exist 15 years from now. Corporate-owned practices tend to be more “take it or leave it” when it comes to negotiating contracts.
The spouse of my husband’s work colleague joined a small physician owned group practice. There were 4 women physicians in the group. Since they were all either pregnant or had small children, each only worked half time – each worked either 8 am to 1 pm or 12 to 5 pm 5 days/week for office hours and each took call every 4th night. Each took weekend call once a month.
