Dear XX,
XX's probation period of six months is going to expire, and we proposed his salary be raised as follow:
XX joined our company on Jun.1st, 2012. We previously intended to offer the post to a foreigner, but without such competent candidates for a long time. Later, recommanded by a headhunter, XX was interviewed and hired by our company. His request for salary, however, has exceeded the level set for this post in our company. Thus, we promised to raise his salary to eight thousand RMB after his probation period expired.
I'll submit related written material to you on next Monday for endorsement, thanks!
