Leave Application (Casual/Medical) :
Every teacher, like any other professional, may occasionally need to take time off from work due to personal matters, urgent commitments, or health-related issues. In such cases, it is expected and professional to submit a formal leave application to the head of the institution, usually the Principal or Headmaster.
Whether it is casual leave (short-term, personal, or urgent non-medical reasons) or medical leave (due to illness or health recovery), a teacher must communicate clearly, respectfully, and officially to ensure smooth functioning in their absence.
What is a Leave Application by a Teacher?
A Leave Application by a Teacher is a formal written request addressed to the school principal or academic administrator seeking permission to be absent from teaching duties for a specific period.
This application must include:
The reason for leave (casual or medical)
The dates or duration of absence
A polite request for approval
Assurance regarding classwork or alternate arrangements (if applicable)
Submitting a well-drafted leave letter helps maintain transparency and ensures that the administration can make necessary adjustments in schedules or classroom duties.
