Sick leave application

Sick leave letters for students and employees: a short sick leave application that works for a manager or a class teacher, plus the full school and office formats. Each says you are unwell, gives the dates you will be away and who is covering, and notes a medical certificate where one is needed, without sharing more medical detail than necessary.

Templates

  • Sick leave application (document): A short sick leave application or email to your manager or class teacher, with the dates you are away, a brief reason, a medical certificate line and who is covering urgent work. Sample application included.
  • Leave application for school (document): A leave application to the Principal in the Indian school format, with subject line, dates of leave, reason and parent signature, for sick leave, family functions or urgent work.

How to use these templates

  1. Pick the school format for a student, or the office format for work.
  2. Tell the AI the dates and a short reason, for example "viral fever, doctor advised rest for three days".
  3. Keep or remove the medical certificate line depending on how long you are off.
  4. Send it by email or message on the first day, then hand in a signed copy when you return if your school or office asks for one.

What a sick leave application needs

  • Tell your teacher or manager on the first morning, before classes or your shift start. The written application can follow.
  • Name the illness only in general terms, such as fever, a stomach infection or a doctor's advice to rest. You do not have to disclose a diagnosis.
  • Say when you expect to return, and that you will update them if that changes.
  • Attach a doctor's certificate for longer absences. Many Indian companies ask for one after two or three consecutive days. In the UK you can self-certify for the first seven calendar days, after which employers can ask for a fit note.
  • At work, mention anything urgent that someone needs to pick up while you are off.

Frequently asked questions

Can I apply for sick leave after I am back?

Usually yes, if you told your teacher or manager on the day. Submit the application and any certificate as soon as you return.

Do I need a medical certificate for one day of sick leave?

Rarely. Most schools and employers only ask for one for longer absences, or for absences next to a weekend or holiday. Check your school or company policy.

How do I write a sick leave email to my manager?

Subject: "Sick leave today, [date]". Say you are unwell and unable to work, when you expect to be back, and who can cover anything urgent. Three or four lines is enough.
