Application for Sick Leave: How to Write One


In this article, we will see how to write an application for sick leave. Basically, sick leave is the leave for absence because of sickness/illness. It is the time off the work when the worker/student stays at home because of a risk to their health.  It is the time that person spends away from work/school because of illness or injury. Many companies provide paid sick leaves which allow the workers to get paid when they are seriously ill and unable to work. During the leave, they need to take care of their health in order to rejoin the organization as soon as possible. Some people misuse the sick leave, which is illegal and you can face some serious consequences (like a suspension or a penalty) for the misuse.

Section 1:

The Opening of a Sick Leave Application:

In the opening of the application, you must use the formal language while writing the application. You must know who you are giving the application to or who the concerned person is regarding leave applications. You need to mention that person’s post. Or if you don’t know to whom the application will be submitted, just write “To whom it may concern”. Here are some examples of how to mention the person:


– The principal,

– The manager,

– The class teacher,

– And many more

After that, you should write the subject of your application. For example,

– Subject: Sick leave application

Afterwards, you can use the proper salutation like “Dear Sir/Ma`am”.


Application Body:

In this section, we normally just start with something which makes the reader comfortable with the application. Afterwards, you need to provide your details to the concerned person such as student number or employee ID number. Then you need to mention the reason for your sickness and have to tell them that you need a break from official activities. Duration of the leave should be stated along with the brief information. You must avoid lengthy passages. The application will be decent if you provide dates of your sick leave. Furthermore, you can promise a medical certificate as a proof of illness which will make the application more reliable.

Section 3:

Details of the Application:

In this section, you need to provide your details like if you are a student you need to write about your course, class, section, class teacher name and if you are working with the company you need to write your post, details about your project and the name of the head of the project. You need to make sure that you provide every single information that can help get your application approved. If you are willing to hand over your work because of the serious illness or injury, you can hand it over to your teammates by referring them to the most concerned person.

Section 4:

Closing of the Application:

In the end, you need to convince the authorized person to consider your application. If you are a student, you must express gratitude to your principal for considering your application. And if you are working with a company, show your thankfulness to the concerned person. This is a major part of your application.

– Yours truly,

– Your Student,

– Yours obediently,

– Yours faithfully,

In the bottom of the application, write your signature, name, date, student/employee ID number and your contact number.

Dear Sir/Madam,

Respectfully, it is to inform you that I am suffering from a severe case of typhoid. I have been an employee of your company for the past 7 years. I have recently been diagnosed with typhoid. Due to this sudden illness, it would not be possible for me to make an appearance at the office for a duration of 1 week.

This situation has deteriorated my health a lot. I cannot do anything properly. It is impossible for me to concentrate on anything. Doctor has suggested me complete bed rest for 7 days. After my complete recovery, I would be able to come back and serve your company again with the same vigilant and attentive inclination.

I hope you take my plea into consideration and allow me a leave for 7 days. I shall be very thankful to you for your kind cooperation and support.

Yours truly,
