Dear PAUL SMITH ,
Many thanks for the assistance you gave last weekend packaging up our priority deliveries. We were struggling and know that our deadlines would have been missed without your help. All of you coming in on your days off showed what a great team you are, and with such colleagues I know that this firm will go from strength to strength. I never thought that I would have such dedicated employees working for me and feel blessed as a result.
