I received your letter yesterday announcing my promotion and I gladly accept the same. Thank you for recognizing the time and effort I have put in the company for five years. It is a promotion I have long been praying and working hard for.
I know that with this promotion comes greater responsibilities. Rest assured that I will fulfill my duties to the best of my ability and I will not fail your trust. I do believe that I am capable of handling the job. The training and experience I have gained in my previous position have made me ready to make tough decisions and resolve problems that come along the way with a level head.
As per your letter, I will be reporting to the human resources officer this week for a general orientation.
Thank you and I look forward to serving the company in my new position.
