Leave application format for school and college students and their parents/guardians, office employees are available here. Students of the school write an application for leave letter to their principal or headmaster to get leave for a short period of time. In the same way, the working people or professionals write the leave application to their managers or supervisors to get leave for a few days. At some point in time, we need to take leave from school or office. But we get the leave only if we write the leaving application letter mentioning the reason behind it to the concerned person. It is really essential to submit a leave application in the office and leave application in school when you are planning to go out for few days with family or friends, or if your health is not well and the doctor has advised you to take rest.
