SAMPLE 1: SICK LEAVE
Dear Ms. Turner,
I am writing this letter to inform you that I need to take a sick leave from work for five days due to a severe throat infection. I will need to remain off of work until September 26.
A letter from my doctor is attached. I apologize for any inconvenience due to my absence from work.
I should, however, be able to occasionally check my email and do some work, from home when possible until I come back to the office. When I return on September 26, I fully intend to do my best to catch up on any work I missed during my absence.
Feel free to contact me at your convenience should you have any questions or require clarification regarding my sick leave request. Thank you for your prompt attention to this matter.
SAMPLE 2: LONG LEAVE (PERSONAL REASONS)
Dear Mr. /Ms. Last Name:
This letter is a formal request for a leave of absence, to follow up on our meeting yesterday. As we discussed, I would like to request a leave of absence from April 1 through June 30, 20XX. I'd be traveling to my home town to take care of my ailing father.
I will return to work on July 1, 20XX.
Please let me know if I can provide further information or if you have any questions. I will make sure I close all my pending tasks before I leave. I would be glad to help with a plan to cover my workload in my absence. I would also be available to answer questions and provide assistance while I am away.
Thank you very much for your consideration in providing me with this opportunity for personal leave.
