This quick note is to let everyone know that I will finally be coming back to work on [date]. The leave of absence provided to me has given me my much needed time to address my [personal events/medical recovery/business trip/vacation/etc.] issues.

I very much appreciate everyone for their patience, encouragement, and support in the entire duration of my leave. I am thrilled about reuniting with everyone and getting back to [name of organization] and enjoying work. I am eager to meeting all of you again soon!
