Absence explanation letter

An absence letter deals with whole days gone and no leave approved beforehand. Written as a letter rather than a form, because the thing being explained is usually why nobody could be told.

After returning from days that were not booked in advance. If the day was worked and simply started late, that is a different note.

Letter explaining unapproved absence

[Date]

To: [Manager name], [Department]
From: [Your name], [Employee code]

Subject: Absence on [date or date range]

Dear [Manager name],

I was absent from work on [date], and on [date] if the absence ran longer. I did not seek approval beforehand, and this letter records why.

[Two or three sentences on what happened. Say what prevented you attending, and keep it factual. Medical detail beyond 'I was unwell and unable to attend' is not required and need not be given.]

[Say why notice was not possible before the shift started, and when you first made contact. If you did reach somebody, name them and give the time.]

[State any evidence you can supply: a medical certificate, a hospital record, an official document. If none exists, say so rather than leaving it unaddressed.]

I would like these days treated as [leave type], or as unpaid days if no balance remains. I understand the decision rests with you and with the policy.

Yours sincerely,
[Your name]  ·  [Employee code]  ·  [Contact number]

How to fill it in

  1. Write it the day you return. The letter is expected. Waiting to be asked for it makes the absence the second problem.
  2. Give dates, not a duration. 'Three days' is ambiguous across a weekend. Two calendar dates are not.
  3. Keep medical detail out. A certificate is evidence. A paragraph of symptoms is oversharing, and your employer does not need it.
  4. Name a treatment for the days. Ask for a leave type or accept unpaid days. A letter that asks for nothing leaves the decision to drift.
  5. Keep a copy. Send it in a form that leaves you a record. Verbal explanations vanish exactly when they matter.

Days settled this way are recorded in PeopleMuster against a leave type with its own annual quota. The balance moves at the same moment the record does. Leave types and quotas.

Questions people ask about this letter

Is a medical certificate always required?

That depends on your policy and on local rules, which differ by country and by length of absence. Check yours before promising one or refusing one.

Can unapproved days be converted to annual leave afterwards?

Often, if a balance remains and the manager agrees. Ask directly in the letter rather than assuming it will happen quietly.

What if the reason is genuinely private?

Say that the reason is personal and that you are willing to discuss it in confidence. That is a real answer, and most policies accept it.
