In all seriousness, this is why you keep copies of your own performance reviews. These are documents signed by both you and your employer showing the above average performance.

Given the above situation, I would respond by walking out the next day in response. Make sure to tell them you have no need of their "recommendation." You have what they believe in writing. Although, an above poster had a good idea of working out those weeks at higher pay. See how much they actually value you.

All prices are based on both Supply and Demand. Not one or the other. Both of you, please remember this for your economic analysis.
