Dear Mr. Steven
The reason for my leave is that my father is undergoing bypass surgery next week and I have to be with him pre, during and post the surgery. He is asked to take complete rest for the next two months after the surgery, so for the 1st one month, I want to ensure he is fine.
I will complete as much work as possible, but in case there is anything pending, I will assign it to my team member John, who will complete the work before the deadline.
I will resume work from DD/MM/YYYY, and in case you have any urgent work, you can contact me on ********* or even email on the company email address. I will get back to you at the soonest.
Waiting for the confirmation of leave.
Yours sincerely,
Marc Jackson
