Imagine managing a baseball team. You’ve got some star players and some very good ones. Never in a million years would you even consider paying them all the same amount or giving them all the same contract terms. After all, some players are far more valuable to the team than others. Giving them all the same deal would cause the stars to look elsewhere and would disincentivize the lesser players from improving.
Back in the real world you manage your medical group. You’ve got some star physicians and some very good ones. Too often medical group leaders think they have to pay physicians (at least ones in the same tenure category) the same and give them all the same contract terms.
Is your “team” really that different?
