Everyone needs to work to earn a living. However, there are times when a person may need to miss work due to illness. In such cases, employers often require a formal excuse letter explaining the reason for the absence.
What is an absence excuse letter for illness?
An absence excuse letter for illness is a written document that a student or employee submits to explain and justify their absence from school or work due to being sick.
This letter explains the reason why a person was unable to attend work due to illness. Depending on the company’s policy, it may need to be submitted either before the absence or after returning to work.

Inform them timely
An absence excuse letter is a formal way to inform your boss or employer about your absence from work. It also serves as written proof that you informed the company about the reason you couldn’t come to work.
At some point in your career, you may need to write this type of letter, so it’s important to know how to do it properly. The following tips can help:
- Keep it professional: Use a formal business letter format. The tone should be respectful and professional. You can type the letter in Microsoft Word or any other word processor.
- Keep it Simple: The letter should be short and to the point. Avoid giving too many personal details or listing all your symptoms. Just mention the dates you will be absent and provide a brief explanation, such as being ill or under medical advice to rest.
- Include essential details: Start the letter with your name and contact information at the top. Below that, include the date, the name and contact information of the person you’re addressing. Begin the letter with “Dear [Manager’s Name],” followed by a clear statement about your absence, for example, “I will be unable to attend work from [start date] to [end date] due to illness.” You can also offer to help ensure your absence doesn’t cause any disruption by saying something like, “Please let me know if there is anything I can do to ensure a smooth workflow during my absence.”
It is necessary to know how to write an absence letter so that your employer is not disturbed by this.

Re. Absence Excuse for Illness
Dear Ma’am,
I am currently working as a Corporate Assistant Manager at your Align House. I have always been a regular and punctual employee. This year, I was honored with an award at the Employee’s Annual Award Ceremony for being one of the most punctual and efficient workers. Receiving this award has further encourged me to remain consistent and dedicated to my work.
Recently, I was unable to attend the office for three days due to illness. I had a high fever, and after medical tests, I was diagnosed with typhoid. Dr. Sophia from Kent Clinics advised me to take complete bed rest for three days. During this time, I informed the admin via email about the reason for my absence.
I attempted to send the presentation I was supposed to submit that day, but a network issue prevented the email from going through, and it went unnoticed. During that time, my phone was switched off, so I couldn’t receive any calls from the office.
When I returned to work, I was shocked to learn that I had been given a salary deduction and a two-day suspension. I understand, ma’am, that being absent for three consecutive days is unacceptable. However, I want to assure you that I did attempt to send the email, and it was unfortunate that it didn’t reach you.
I sincerely apologize for the consequences of my carelessness. I promise to be more responsible in the future and am committed to improving my performance moving forward.
Ma’am, I kindly request that you cancel my suspension orders and instruct the accountant not to deduct my salary. I am currently facing severe financial difficulties and hope you will understand and consider my situation with compassion.
I pay my thanks in anticipation.
Sincerely
(Signature)
