(names omitted for online privacy reasons, of course) Dear ****: I regret to inform you that I will be leaving my position as Staff Assistant IV at the ***** School on June 9, 2006, to resume my previous career as a copywriter. I am willing to leave earlier than June 9 if you feel it would give ***** more time during the summer to adjust to the transition. Im grateful to have had the opportunity to work with such a supportive team, and my very best wishes go to everyone at *****. Sincerely, I'll be submitting this in a couple of days. I'm just nervous about how it will go over, so I want to sound as professional as possible.
