Physician here.
Medicine is one of the few professions in which capital is tied to labor (at least of the licensed independent clinicians). Hospitals, clinics, etc., can't run any test, provide any service, perform any surgery, without a physician (or other licenses clinicians) order.
Health systems rely on their physicians to drive clinical practice. Physicians are the experts after all. It's a mutually beneficial relationship, but at its core, it is a partnership. This partnership certainly has it's ups and downs. But this is what happens when the health system forgets that it is a partnership.
