Looking for a casual leave application sample? Whether you need to write a CL application for leave, casual leave email, or application for casual leave in office, this guide has got you covered. The first thing to remember is that every organization has different procedures for taking and requesting casual leaves (CL).
Sometimes, your CEO or the appropriate authority may require you to submit a casual leave application. Knowing how to write a casual leave application and what information to include in such letters can help you write one for yourself, following proper etiquette. There are several examples to inspire you in this article that outline how to write a casual leave letter.
What Is A Casual Leave Application? :
Generally, a casual leave application is a formal, written request you submit to your employer or manager. It is also known as a CL letter or application for casual leave in office. If you want to take time off from work for unforeseen situations and urgent personal work, in your application, you must mention-
- Why do you want a leave,
- How many days do you need, and
- How your absence could affect your work.
The application letter can be in the form of an email, a printed letter, or both.

Provided that, most of the organizations now have a proper HRMS System. If your organization also has a smart HR solution like Tipsoi, you can apply for your leave of absence through the app. And get your advisor’s OK quickly through it. In addition to that, if you are unable to apply for leave in time, your supervisor will get a notification of your absence. This is because this HR solution frequently links to a biometric identification system that checks when employees come and go from work.
Reasons for Casual Leave
Casual leave is often taken for personal or urgent matters that cannot be postponed. When writing your application, choose one of these common casual leave reasons or provide a valid explanation that aligns with your situation. Here are some common reasons for requesting casual leave:
- Personal errands or commitments
- Family emergencies or events
- Medical appointments or check-ups
- Attending weddings, funerals, or other ceremonies
- Rest and relaxation after continuous work pressure
What To Include In A Casual Leave Application:
Following a proper casual leave format ensures your application is professional and adheres to workplace standards. When you ask for office leave—whether it’s through a casual leave email, CL application format, or a handwritten letter—you should include the following information:
- Application date.
- The name and address of the manager to whom you are writing.
- A brief explanation of the letter’s purpose or subject
- An appropriate salutation containing the recipient’s name or title

How To Write A Casual Leave Application: Step-by-Step Guide with Samples
Wondering how to write a leave application to your boss? In order to understand how to write a casual leave application—be it an application for casual leave in office or a casual leave request mail to manager—here is a step-by-step guide:
1. Check your company’s casual leave policy Before Applying:
Take a look at your employee handbook to see how many CL leaves you can apply for before you submit your CL application. This is because many organizations restrict the number of casual leaves an employee can take at one time. For instance, some organizations may specify guidelines on writing an application for two days of casual leave or submitting an email for casual leave. Contact human resources to find out whether they prefer printed or emailed copies of leave applications. If you want to write an approved CL application, you need to know all of this information.
2. Address Your Casual Leave Mail to Your Supervisor or HR Executive:
Find out who approves your leaves in your employee handbook. The letter can go to your manager, supervisor, or both manager and HR.
3. Use a Professional Salutation in Your Casual Leave Request
Start off with a professional salutation since this is a formal request. It is better to use official greetings like “Dear [recipient’s last name]” instead of casual ones like “Hi/Hello [recipient’s last name].” It is acceptable practice to use Mr./Ms./Mrs. followed by the last name of your manager or HR executive even if you are familiar with the first name. A good example would be “Dear Mr. Sakib”.
4. Choose a clear subject line
Write the subject line of your CL application letter because it summarizes what you will be writing. The subject line of your letter should be clear and professional so that the recipient understands what the letter is about.
Below are some examples of subject lines that you can use as inspiration:
- Request for a one-day casual leave.
- Casual leave application due to a family member’s illness.
- There needs to be two days of casual leave.
- A request for casual leave.
- Request for casual leave to take care of urgent personal matters.
Subject Line Suggestions for Casual Leave Applications
A clear and concise leave subject line helps ensure your application gets noticed promptly by your manager or HR executive. Here are some examples you can use:
- “Request for One-Day Casual Leave on [Date]”/ “Request for One-Day CL on [Date]”
- “Casual Leave Application – Family Emergency”
- “Application for Half-Day CL on [Date]”
- “Request for Casual Leave Due to Medical Appointment”
Choose a subject line that reflects the purpose of your leave while keeping it concise and professional.
5. Give your reason for requesting casual leave
In the first paragraph, describe why you are requesting leave and state your reasoning. Common reasons include personal errands, family emergencies, or attending special occasions. You can refer to our section on casual leave reasons list for more examples. By doing so, you clarify your intention and make the recipient more comfortable with the information that follows.
6. Specify when your leave begins and end
Provide your manager with a start and end date for your leave after explaining your reasons for requesting it. In your application, you should clearly mention the dates of your leave, even if it is for two days. By doing this, you can avoid confusion and miscommunication with your manager.
7. Describe how work will be carried out during your absence
In the case of your absence, it is always advisable to give your team as much time as possible to prepare. So, you should include in your application letter the name of the person you are delegating your work to, as well as if you are capable of completing your high-priority and time-sensitive projects on time. You should be aware that if you are taking a CL for some emergency purpose, you must include that you will be available on the phone to answer any questions and that you will make sure you check your emails on a regular basis.
8. Don’t forget to give your contact info
Give your manager your personal details, including your phone number and email address, so he or she can reach you if anything goes wrong.
9. Feel free to send your gratitude
If you give short notice for taking a CL, apologize to your manager if you do so. If you are thankful that your manager has understood your situation, thank them personally.
10. Put a bow on your application letter
In general, a formal closing salutation should be used at the end of your letter. Here are some salutations that you can choose from:
- Sincerely
- Best wishes
- Yours truly
- Regards
11. Consider including a signature
In the case that you are sending your application via email, please write your name below the closing statement. On the contrary, if you are handing out a printed letter, you should add your signature below the closing salutation. In addition, you should type your name at the bottom of the letter if it is printed.
Top Tips for Writing an Effective Casual Leave Application for Office Use
If you are writing a CL application—whether it’s an absence of leave letter for work or an email to HR requesting casual leave—here are a few tips to keep in mind:
Don’t forget to submit the letter on time:
It is important to inform your manager at least one day in advance that you plan to take casual leave. Due to this, they will be able to prepare for and work on pending work while you are away as a result.
Ensure that your language is formal and professional
It is imperative that you use formal and professional language when you ask for casual leave as it is a formal document.
Short and sweet is the key
Ensure that only the necessary information is stated, such as the dates of leaving and resuming work, as well as the reason for taking a leave of absence.
Take the time to proofread your application
Ensure that you reread your leave application before you send it in order to ensure that it is free of all mistakes in punctuation and spelling. If you make any grammatical errors in your letter, it will look unprofessional and may even cause confusion for the reader.
