Respected Madam,

With huge respect, I, Amrita Gowda, TGT English, beg to state that my condition is still not better. I am on leave from 10th of February 2022, and I had mentioned that I shall be on leave for this week and would join the office from 18th February 2022, but as per the current reports, my wounds would still take some time to heal, and according to the doctor’s advice, I will have to bed rest for one more week. I have had a conversation with Mrs. Deepa Patil to take my allocated 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 because of me. 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.

Thank you.

Yours faithfully,
