This strikes me as nonsense corp-speak.
"Market dynamics" force you to pay your highest performers barely more than your lowest performers?
How exactly does that work?
Disparity between executive salaries and worker salaries are astronomical, but when it comes time to reward your highest performing workers you can't find any possible way to increase their take home? Between salary, bonuses, stock grants, retirement plan matching or any other possible methods of compensation, your hands are absolutely tied? Because of "Market Dynamics and Pay Equity"?
Come on.
