I regret to inform you of my impending resignation as Development Officer with Company Name. My final day will be Friday, October 3 2014, and this letter serves as my official two weeks’ notice. I have been offered a fundraising position with the Alumni Affairs Division of Company Name and have accepted the offer. I believe this new position is a forward step in reaching my career goals. I do appreciate your attention and understanding at this time.
I am more than willing to assist in any way possible to make my departure as seamless as possible. I will inform all of my immediate staff and will work to finish any open projects. You can also expect my cooperation in training my replacement if need be. I can be reached at 000-000-0000 or email@example.com should you have any questions.
I am very appreciative of all I have gained as Development Officer here at Company Name. I will miss my colleagues and hope that you all have much future success. Thank you so much for your attention to this matter.
