What is the productivity difference between an "A' employee and a "C' employee doing the same job?

Has anyone done a study of the difference between a frontline"A" employee and a "C" employee?

In one of the Convenience Store companies I worked with, when we moved an A employee to a store that had only average inside sales, in less than two months, inside sales were up over 20% on the shift that she worked.

Does anyone have an other examples of the difference between an A and a C level employee doing the same job?

In my experience, adding one person who is a team player and creates a team environment can change the energy completely in a department. Changes the motivation and the energy from negative to positive and therefore improves productivity and performance. Not easy to define why but it happens.
