Sorry to be so blunt, but it's time you left.
It's not that you were all that bad of a year, but you were one of the worst years in my career at work. There were a lot of problems and issues that we faced this year, and I am glad that you are leaving and am really looking forward to 2018. We know what needs to be changed, and I am confident and optimistic that we, meaning my department and I, will do better in 2018.
I do thank you for not giving us any major health issues this year. Other than my bought with the mega cough that was going around in March, the 'Rents and I had a great year health-wise. I thank you for that.
I also thank you for my opportunity to become a chicken farmer. If you'd asked me this time last year if I would want to raise six chickens I would have told you that you were crazy. But thanks again for the opportunity.
I'm not going to say I'm sorry to see you go, but as always, I am thankful for the lessons you taught me this year.
