why isn't this a better explanation: High performing, "desirable" or "skilled" employees get enticed (i.e. rewarded) for jumping to a new employer. Average schlubs do not.
explanation from TFA:
Why are people who jump ship rewarded, when loyal employees are punished for their dedication? The answer is simple. Recessions allow businesses to freeze their payroll and decrease salaries of the newly hired based on “market trends.” These reactions to the recession are understandable, but the problem is that these reactions were meant to be “temporary.”
