Dear Boss,
I have enjoyed working here these past several years. You have paid me very well, given me benefits beyond belief. I have 3-4 months off per year and a pension plan that will pay my salary till the day I die and a health plan that most people can only dream about.
Despite this I plan to take the next 12-18 months to find a new position.
During this time I will show up for work when it is convenient. In addition I fully expect to draw my full salary and all the other perks associated with my current job.
Oh yeah, if my search for this new job proves fruitless, I will be back with no loss in pay or status. Before you say anything, remember that you have no choice in the matter. I can and will do this.
Sincerely,
Every Senator or Congressman running for President.
Try that at your job and tell me how it works out.
