Why Send a Sick Leave Letter?

Each company has its own policy for reporting illness. Some may require you to send a sick leave letter, while for others, a phone call or email may suffice. However, it can be good to send a sick letter even if you don’t need to, especially if you are facing a prolonged absence. It gives you the chance to set out the situation in writing, including dates and how long you expect to be off. It keeps communication clear and ensures that everyone’s on the same page. It can also be useful to ensure the HR department has a written record of when you went off sick, in the case of any claims or disputes.

Your sick leave letter should contain concrete information about your illness, how long you expect to be off work and what will happen with your workload while you’re gone. Putting all of this into a formal letter will be much appreciated by your employer, as it keeps them in the loop and makes their job easier.

How To Write a Sick Letter?

Your sick leave letter should be written in the style of a typical professional business letter. Use proper letter formatting, with your full name and address and the company name and address at the top. It’s also very important to include the date clearly at the top of the letter.

Greet and introduce

Start your letter by addressing your manager with “Dear Mr. [Name],” followed by a double-line break. Then briefly introduce the letter by outlining that this is a sick leave letter notifying the company of your leave of absence.

Explain the situation

In the main part of the sick leave letter, explain what health problems you are facing and how long you are likely to be absent from work, providing specific dates. If you have a sick note from your doctor, let them know that you’ve attached this to the letter.

Mention handover of work

Let your employer know if any of your work will be impacted and if they need to arrange any cover of work in your absence.

Express your gratitude

Thank your employer for their understanding. Little tokens of politeness and recognition are always appreciated.

Sign off

Sign off your letter with a formal closing phrase, such as “Best wishes” or “Kind regards,” followed by your name and your signature if it’s a printed/handwritten letter.

Sick Leave Letter Sample

Here is an example of a sick leave letter:

Dear [Manager’s name],
I am writing to let you know that I, unfortunately, need to take some sick leave from work.
Last night I came down with food poisoning and my doctor has recommended that I take a week off work and stay on bed rest to recover. Please see attached sick note from my doctor. My leave of absence will therefore start today and I plan to return to work on Monday 5th July. If the situation changes, I will notify you immediately.
Please could you arrange for someone to monitor my inbox during my absence and deal with any urgent requests? All other work can wait until my return when I will ensure to catch up on everything straight away.
Thank you for your understanding of this situation and apologies that I have had to take a leave of absence at such short notice.
I look forward to returning to work once I’ve recovered.
Best regards,
