A casual leave application is a formal request written by an employee or student to seek permission for short-term leave. Casual leave is usually granted for personal reasons such as attending family functions, handling personal matters, or dealing with emergencies.

Unlike sick leave or earned leave, casual leave is typically limited to a few days and must be approved by the concerned authority before being taken.

When Should You Write a Casual Leave Application?

You should write a casual leave application in situations such as:

• Personal or family commitments

• Attending social or religious events

• Short personal errands

• Unplanned but non-medical situations

• Travel for urgent personal reasons

Submitting the application on time helps maintain professionalism and workplace discipline.

Key Elements of a Casual Leave Application

A proper casual leave application should include the following components:

1. Subject Line

The subject should clearly state the purpose of the application.

Example:
Subject: Request for Casual Leave on [Date]

Use a formal greeting such as “Dear Sir/Madam” or address the recipient by designation.

3. Reason for Leave

Mention the reason briefly and clearly without oversharing unnecessary details.

6. Closing Statement

Thank the recipient and request approval politely.
