To: Robert Bush, Sales Manager
From: Bob Wang, Sales Development
Date: May 6, 20XX
Subject: Terminating Engagment
Mr. Bush, I have worked in the Sales Development as a salesman for six years, and I have been satisfied with this position.
However, a friend of mine introduced me to ABC Company, and I have decided to accept a post that will give me greater possibilities for promotion and an increase in my salary. I therefore write this memo as formal notice to terminate(终止) my engagement with you one month from todays date.
