Dear Mr./Ms. Bossname,
I am submitting my resignation, effective two weeks from this date.
I'd be happy to ease in the transition and would especially like to recommend that Nina be promoted to my role. She has done standout work, including on Project B, which is still in process.
Besides Project B, I've been handling several elements of Projects A and C. My files are up-to-date, and you can check with Chuck on the remaining data we need to loop in.
I would suggest that you reconsider the open-office concept, as many of us have found it to be disruptive. Since I'm on my way out the door anyway, I won't hesitate to tell you that it has reduced productivity while doing nothing to increase camaraderie. You have a great staff that already knows how to collaborate.
I am owed four weeks' vacation time, and a check can be mailed to my home address that you have on file or direct-deposited to my bank.
If you'd like to engage me as a consultant, we can negotiate an hourly fee.
Thank you for the opportunity to be a part of this team. I wish the best for you and the company as a whole.
