Dear Mr./Mrs./Ms.,
I regret to have to let you know that I am tendering my letter of resignation from the current position that I currently hold – Senior Marketing Manager for Suits and Shirts Company Limited. My last working day in the company will be 10 December 2007.
I am taking up a new position in ABCXYZ Company, a non-profit making institution. I will miss working here. However, I look forward to the direction of my new career.
I appreciate the support you gave me over the 5 years that I worked with you. I wish you all and the company as a whole all the best. Do not hesitate to keep in touch using my cell phone number which remains the same.
Yours sincerely
