Dear Andrew hall,
I believe that the work you have put in to ensure that the catalog has been published in time for this season should be complimented. I know that the tight deadline has meant you undertaking weekend working, not helped by some data corruption, and I also have never seen you complain once. I hope that we will not be faced with the same situation in the future, but in this instance it is only your hard work that has allowed us to succeed. I know that you have a very bright future with us.
Sincerely,
Arah smith
