Dear Mr XXX,I submit this request for resignation with a heavy heart. The company growth requires everyone's hard work and due to my personal reason, I am unable to contribute, and I can't stay in the company without any contribution, as such, I seek for approval to leave.The company now is at the stage of growing, all colleagues are passionate and full of figthing spirit, and at this moment, I can't share the joy due to my personal reason, I feel so sorry.In order to make sure the transition is smooth, I will be leaving the company 1-2 weeks after I submitted my request, I hope my request will be approved. Thank you for all the support and trust given during my period of service, I wish the company growing tremendously! To the management and all colleagues, happy working.Thank you.Yours sincerely,.......2008.12.16
