How to ask for sick leave from the new principal

How does a teacher ask for leave from the principal? The sample essay is as follows:

1. Be polite at the beginning, Dear Principal, etc.

2. Indicate the reason for the leave (write (The necessity and importance of the reason)) If you are going to do something, you can ask someone to write a certificate for you. (More authentic)

3. Indicate the time of request for leave (how many days, or the day of the month to the day of the month)

4. At the end, compliment the principal again ( This will make the principal feel good)

If an accident occurs during this period, the school leadership has nothing to do with it and it will be my own responsibility.

Note: You must be sincere when sending the leave request!
