Sick Day Email Sample

Updated on: November 10, 2019

Being unwell is bad enough; having to tell your boss or supervisor that you won’t be able to come to work is even worse.

But if you will not be able to work, it is essential to let your employer know on time.


Writing a letter is cumbersome and will take ages to reach your office. Text messages may not be considered too professional. The best way to do this is to write an email to your boss and ask for a day off.

A sick day email is a simple way of letting your boss and colleagues know that you will not be coming and why you have decided to take the day off.

How to Write a Sick Day Email?

•  You must be very clear about your reason – if you have an illness that requires you to stay off from work for more than a day, mention it in your email.

•  If possible, attach a scanned copy of a doctor’s note with the email to provide credence to your claims of being unwell.

• Since you are writing an email while you are not feeling too good, so keep it short.

• Make sure that you incorporate all the information that your supervisor will need.

• Include suggestions on how you intend to make up for a lost time at work and if you plan to do part of your work at home.

Re: Sick Leave


Dear Ms. Nicola:

I am writing to inform you that I will not come to work today as I am feeling unwell since I came back yesterday.

In fact, I had had a high fever and a heavy head at work all day yesterday. Additionally, a quick trip to the ER last night confirmed that I had contracted the “bug.”

The ER doctor suggested that I take at least two days off from work. That is because I am contagious and will risk infection to my coworkers.

Rest assured that I will manage my work from home during my leave. Also, I will be in continuous contact with my clients through email and phone.

Please find the doctor’s note attached to this email. I would appreciate it if you could forward this email to HR so that they can formally process my leave. As of yesterday, I had six sick leaves left for the rest of the year, so I am assuming it is not a problem to take two days off.

Thank you very much,
