Dear Mr./Ms
Please accept my resignation as associate chemist at the GERT Institute. I plan to leave my job here on September 30, 19–, taking a few days of annual leave just prior to that effective date. As you know, my primary interest has been in the oil and gas industry. Therefore, I’ve accepted a position with Fury Refining, Inc., that should put me back in touch with my “first love.” Although I’m eager to accept the challenges in this new position, I regret leaving the institute. You and the organization as a whole have treated me very well over the past three years. I won’t forget the friendship and professional growth I’ve experienced as an employee here. Best wishes to all of you for years of expansion here.
Sincerely,
