Write A Casual Leave Application

In order to understand how to write a casual leave application, here is a step-by-step guide:

1. Check your company’s casual leave policy:

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 due to the fact that many organizations restrict the number of casual leaves an employee can take at one time. Contact human resources to find out whether they prefer printed or email copies of leave applications. If you want to write an approved CL application, you need to know all of this information.

Find out who approves your leaves in your employee handbook. The letter can go to your manager, supervisor, or both manager and HR.

3. Put a professional spin on your salutation

Start off with a professional salutation since this is a formal request. It is recommended that you use formal salutations like “Dear [recipient’s last name]” instead of informal 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.

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.

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.

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
