Older employees can use this resignation letter to announce their retirement to a boss.
Please accept this letter as signifying that I will be resigning from my position as of (July 30). In fact, I will be retiring as of that date!
I will be taking a vacation of three weeks beginning shortly after my resignation. Therefore, I won't be available to help with my replacement's transition during that period. But if I can be of any help after that time, please feel free to get in touch with me.
I have enjoyed working for (the company) and have made a great many friends there. My best wishes to you all.
