Dear Sir,

I apologize to inform you that I will be leaving the company by the end of September. Recently I have been offered a jab as Production Manager by XYZ company. It is a very great opportunity for me to advance my career that I can’t let it goes.

I have been with ABC company for almost 3 years already that I have been enjoying working here so much. It was a very great memory with my helpful and friendly colleagues especially you as my manager.

I would like to thank you very much for teaching me so many things and I do hope that we can maintain good relationship in the future.

Best regards,

It is quite hard to write such leaving letter. It might irritate your feeling and it is quite emotion; however, it is important that you have to leave for better position in another firm. Mentioning previous memory with colleagues should be very important to show how you feel and it is a good way to keep the relationship with them in the future.
