I think you resignation letter needs a little warmth. Maybe you could include something like - Thank you for the opportunity to be a part of this institution for the past _ years. Warm thoughts and best wishes to all of you.'
If you don't have warm thoughts then just 'best wishes to all of you.'
My RIF notice wasn't particularly warm...
"In closing, I would like to quote Dick Cheney..."
I have never understood all this agony over how to quit a job. Employers routinely terminate people without agonizing.
Perhaps if one worked in a small business, partnership, etc., but with megacorp, totally agree!
Short and sweet, that's good. Given my boss is a-hole, I want to write all the reasons why he has screwed up many of his employees' life. I want to write managing by fear & intimidation is poisonous approach in dealing with his subordinates. I want to write he is the main reason I am quitting. Yadi, yadi, yada. But it would only lower me to his level and I will probably stick with your approach.
