Commendation and Refusal of Request for Raise
This is to acknowledge your letter of 12-12-2012. You are definitely to be commended for your progress during the past two months. I do believe, however, that your recent request for a raise is premature. I would suggest that it would be more appropriate to discuss a salary increase after you have worked here for six months. If you continue on the same path, I am certain that your timely request will be given careful consideration. You are doing a fine job, keep up the good work!
