Dear Mr. John,
I am writing to you as soon as I heard the news regarding your departure. In addition, I have to express my utmost sadness due to seeing you leaving us so soon.
Firstly, I must respect your decision for leaving, which I am sure is not an easy choice to make, but I can’t help but feel sad about working without you.
Secondly, I should give credit where credit is due. This company may never find a manager as efficient, supportive and friendly as you were. Not only were you a role model for our team but also you were a great asset to the company.
Lastly, please let me know what your next step is as well as when will be your last day with this corporation. Also, please let me know how to contact you in the future.
Looking forward to hearing from you.
Sincerely,
