Suppose You Are Running A Medicine Company.you Gave A Task To One Of Your Staff Members To Make A Survey And Complete It With In Two Months Time.he Completed His Job In One Month Only .how Would You Write Him Formal Letter In Which You Would Appreciate His Efforts And Promise To Celebrate It As An Event?
I am writing to express my appreciation in the work you have recently submitted. Not only did you set the questionaire/survey but you delivered the results well within my deadline. In recognition of your work I would like to...How are you going to "celebrate the event"?......................................... A copy of this letter has been placed in your personal/personnel file.
Depends on how good you consider the effort was, you can continue...
Please continue your efforts on behalf of the Company, I will be watching your progress with interest.
Hope this helps, but I do not know why you used a Capital Letter in your question for the majority of words.
