Taking a leave from work or studies is something that everyone is entitled to. But when you are taking a leave from work, you should make sure that nobody else at the workplace is getting troubled because of your absence. Similarly, when the school or college authorities take the responsibility for the students, it is also the responsibility of the students and their guardians to know about their know bouts when they are taking a leave.

Presenting a properly created sick leave application is all that is needed in both cases. A well-formatted and properly written sick leave application letter helps in offering a proper picture of your absence reason and also helps the authorities in taking the right decisions, if and when required.
