Subject: Thank You Leave Letter
Dear Sir/Maam,
I Would Like To Convey My Sincere Thanks In Having My Leave Application Approved From The ______until The ______.
Initially, I Was Quite Hesitant About Its Approval, Given The Timing Of The Leave Coinciding With The Performance Review For The Merger As Well As The Short Notice On The Submission Of The Application. I Thought That Carrying This Out Would Have An Adverse Effect On My Standing Within The Department.
As You Are Aware, I Need This Leave To Undergo My Operation To Remove A Tumour That Has Accumulated In My Leg, And I Am Incredibly Thankful To You As Well As The Company For Being So Understanding Of My Condition.
Once Again, I Would Like To Convey My Gratitude For Approving The Leave, And I Hope That I Can Make It Up To You In The Future.
Yours Sincerely,
