The letter with to request a leave

I'm writing to request some unpaid leave next week.

My sister Ann is pregnant and she have has to go in to hospital next week. She needs my help to drive her and her things and maybe she will may need something else. Her husband will not be able to be with her. He is going in an important business trip.

I need to take three days off from Tuesday 17th to Friday 21th.

I was talking with our team-lead and he has said that we can change the order in of our tasks. I need to do the most importants tasks. I have already done one of these tasks. I'm sure I will also do another the same.

I would be very grateful if you give me these days off. My presence is very important for my sister.

Your sincerely,

Tatiana Z.
