How to Write a Sick Leave Application in English

  1. Name the illness simply. "Fever", "stomach pain" or "viral infection" is enough. You do not need to describe symptoms in detail.
  2. Give exact dates. Write the start date, end date and number of days, so attendance can be marked correctly.
  3. Say whether you are writing before or after. If you are already back, write "I was absent" and say you have rejoined.
  4. Show you will catch up. Students can mention notes and homework. Employees can say who is handling their work.
  5. Keep it short. A school application is about 60 to 120 words. An office letter can be a little longer.

If you need the same letter in Hindi, use the leave application in Hindi page.

Tips for Writing a Sick Leave Application

  • Send the application on the first day of leave if you can. If not, give it on the day you return.
  • For one day of fever, a short note is enough. For three days or more, attach a doctor's prescription or medical certificate.
  • Young students, especially in primary classes, usually need a parent to write or sign the leave letter.
  • In an office, tell your manager by phone or message first, then send the formal email the same day.
  • Check your company's leave policy for how many sick days you get and when a certificate is needed.
  • Do not write a false illness. Schools and offices may ask for proof, and it can hurt your trust.
  • Keep a copy of every medical leave letter. It helps if attendance or salary is questioned later.

Questions people ask

How do I write a sick leave application for school?

Address it to the principal, write the date and a short subject, then say your name, class, illness and the dates of leave. End with "Thanking you, Yours obediently" and sign with your name, class and roll number. Keep the body between 60 and 120 words.

What is the difference between sick leave and medical leave?

In daily use they mean almost the same thing. "Sick leave" is common for short illness like fever. "Medical leave" is often used for longer treatment, a hospital stay or surgery, usually with a medical certificate.

Do I need a medical certificate for a sick leave application?

For one or two days, most schools and offices accept the letter alone. For longer leave, or if the rules of your school, college or company say so, attach a certificate from a registered doctor.

Can I send a sick leave application by email?

Yes. Most offices and many colleges accept email. Use a clear subject like "Sick leave today", keep it short, and copy HR if your company asks for that.

What should I write in the subject of a fever application?

Write "Application for leave due to fever" or "Leave application for fever". Keep the subject under 10 words.
