How to Write a Leave Extension Letter?

Generally, it is very hard for your higher authorities to approve a long leave but a few cases are considered, looking into the genuineness of the situation. So while writing a leave extension letter, you must give valid and honest reasons for extending your leave. Also mention the work allocation done on your behalf. This will let them know that you are responsible enough to take care that everything is being done without any postponement. Furthermore, see to it that you stay to the point and keep the letter short and simple.

Sub: Requesting a leave extension


Respected Madam,

I, Amrita Gowda, TGT English, beg to state that my health condition is still not better. I have been on leave from the 10th of February. I had mentioned that I would join the office from 18th February, but as per the current reports, my wounds would take some more time to heal. The doctor has also advised complete bed rest for one more week. I have had a conversation with Mrs. Deepa Patil about handling my classes, and she has agreed to the same.

Requesting you to kindly consider my leave extension request till the 25th of this month. Apologies for the inconvenience caused. I am attaching all the medical reports along with the letter for your reference. I hope you understand the situation and consider my leave extension request. I shall be highly obliged to you for the same. Waiting for a positive response from your end.

Thank you.

Yours faithfully,

Amrita Gowda

Dear Sir,

I, Ashish Verma, with employee ID E098765, am writing this mail to inform you that I had taken leave from 10/02/2022 to 17/02/2022 as I had tested positive for COVID-19. Yesterday’s test result still shows positive, and my symptoms are severe. I need to rest for at least a month as per the doctor’s advice. I have allocated all my work to Mr. Shiv Kumar and Mrs. Vaishali, and they have agreed.

I request you to extend my leave till 30/02/2022. I shall, however, try to make it before the mentioned date. Sorry for the inconvenience caused. I hope you understand the situation and consider my request. I shall be highly obliged for the same. Awaiting your response.

Thank you.
