How to Write a Sick Leave Application (Step-by-Step Guide)
A sick leave application should be clear, structured, and professional. Follow this step-by-step guide to ensure your request is properly formatted and well-received.
Start with the Date and Recipient’s Information
The first step in writing a formal sick leave application is to include the date of writing and the recipient’s details. This ensures that your request is properly documented and addressed to the right person.
How to Format This Section
At the top of your application (for a formal letter), include:
- Date: The date when you are writing the request.
- Recipient’s Name & Designation: The name of your manager, HR personnel, principal, or teacher.
- Company/School Name: The name of your workplace or institution.
- Address (if applicable): For formal letters, include the organization’s address.
Example Format for a Formal Letter
[Your Name]
[Your Designation (if applicable)]
[Company/School Name]
[Address (if required)]
[City, State, ZIP Code]
[Email Address]
[Phone Number]
[Date]
To,
[Recipient’s Name]
[Recipient’s Designation]
[Company/School Name]
[Address]
[City, State, ZIP Code]
Example Format for an Email
If you are sending a sick leave request via email, you can skip the address details and start with a clear subject line instead.
Subject: Sick Leave Request – [Your Name]
Dear [Recipient’s Name],
Write a Clear Subject Line
The subject line is essential when sending a sick leave request via email because it immediately informs the recipient about the purpose of your message. A well-written subject line ensures your request is immediately understood and helps streamline the approval process.
How to Format the Subject Line
A good subject line should include:
- The type of leave (Sick Leave Request).
- Your name (optional but useful for clarity).
- The leave dates (if applicable).
Examples of Professional Subject Lines
- Sick Leave Request – [Your Name]
- Request for Sick Leave on [Date]
- Medical Leave Request – [Your Name]
- Sick Leave Application: [Start Date] to [End Date]
Politely Address the Recipient
A professional sick leave application should always begin with a polite and respectful greeting. Properly addressing your manager, HR representative, principal, or teacher sets the right tone for your request.
For school or college applications, address the recipient based on their title:
- Dear Principal [Last Name],
- Respected Professor [Last Name],
- Dear Teacher,
If you are writing to your manager, supervisor, or HR department, use a formal greeting such as:
- Dear Mr. Smith,
- Hello Ms. Johnson,
- Dear HR Team,
If your workplace follows a casual communication style, using the first name may be acceptable:
- Hi John, (Only if your workplace has an informal culture.)
Clearly State Your Leave Request and Specify the Duration
After greeting the recipient, your next step is to state your request clearly while specifying the exact dates of your leave. Keeping this section concise and professional ensures that your manager, HR department, or teacher understands the request without confusion.
Your request should include:
- A direct statement that you are requesting sick leave.
- The exact dates of your absence.
- A brief reason (optional but recommended for transparency).
- Your expected return date (if known).
Examples of Clear and Professional Leave Requests
- I am writing to formally request sick leave from April 10 to April 12 due to illness. I plan to return to work on April 13.
- I would like to request medical leave on July 5 for a scheduled doctor’s appointment and recovery.
- Due to a minor health issue, I will not be able to attend work on March 5 and will resume my duties on March 6.
If your return date is uncertain, acknowledge the possibility of an extension:
- I will be on medical leave starting October 3. I will update you on my condition and confirm my return date as soon as possible.
Provide a Brief Reason for Leave
While stating the reason for your sick leave is optional, it can add transparency and help your employer or institution understand the necessity of your absence. Keep your explanation brief and professional, avoiding unnecessary personal details.
Your reason should:
- Be concise and relevant.
- Maintain professionalism by avoiding overly casual phrasing.
- Include medical documentation if required by company policy.
Examples of Professional Sick Leave Reasons
- I am experiencing flu symptoms and need to take leave from March 5 to March 7 to rest and recover.
- I have a scheduled medical procedure on June 10 and will require leave until June 12 for recovery.
- Due to a high fever and a doctor’s recommendation, I am unable to attend work on August 15.
- I am experiencing a migraine today and need to take sick leave on November 3.
Mention Medical Documentation (If Required)
Some companies, schools, or institutions require medical proof for sick leave, especially if the absence is for multiple days. If your employer has a policy requiring a doctor’s note or medical certificate, it’s best to acknowledge it in your application.
If documentation is not required, you can skip this step unless you feel it strengthens your request.
If you are attaching a medical certificate or doctor’s note, mention it briefly without over-explaining:
- As per company policy, I have attached my medical certificate.
- I can provide a doctor’s note confirming my medical condition if required.
- As per HR guidelines, I will submit my medical report upon my return.
If you need additional time to obtain the document:
- I am in the process of obtaining a medical certificate and will submit it as soon as possible.
For urgent or unforeseen medical emergencies, where you don’t have documentation immediately:
- Due to an unexpected illness, I am unable to provide documentation at the moment but can submit it if required.
Offer Work Coverage Details (If Needed)
If your absence may impact work responsibilities, it’s professional to mention how tasks will be managed while you’re away. While not always required, providing a work coverage plan reassures your manager that your leave won’t disrupt operations.
If you work in a team-based environment or have ongoing projects, briefly state who will be handling your tasks. This may not be necessary for short sick leaves, but it’s a good practice for longer absences.
How to Offer a Work Coverage Plan
If a Colleague Will Cover for You:
- I have informed [Colleague’s Name] about my leave, and they have agreed to handle any urgent tasks in my absence.
- To ensure continuity, [Colleague’s Name] will be available for any critical matters while I recover.
If You Are Preparing Work in Advance:
- I will ensure that all my current assignments are up to date before my leave begins.
- I have scheduled my tasks accordingly and will provide a status update before my last working day.
If No Backup Is Available:
- During my absence, I will not be available to respond to emails, but I will complete all urgent tasks before I leave.
- If anything urgent arises, please direct inquiries to [Alternate Contact].
Request Approval Politely
After outlining your leave request and any necessary details, the next step is to politely ask for approval. Instead of assuming your leave will be granted, phrase your request in a way that shows respect for company policies and your manager’s authority. A well-worded request ensures that your leave is processed smoothly.
A polite request for approval should:
- Show consideration for work responsibilities.
- Allow room for discussion in case adjustments are needed.
- Maintain a professional and respectful tone.
Examples of Professional Approval Requests:
- Please let me know if my request is approved or if any adjustments are needed.
- I would appreciate your confirmation of my leave request at your earliest convenience.
- If these dates conflict with any scheduling needs, please let me know, and I am happy to discuss alternative options.
- I understand this is a busy period, so if any changes are required, I am open to discussing an alternative arrangement.
If company policy requires formal confirmation:
- I will wait for your official approval before making any necessary personal arrangements.
- Please confirm if my request aligns with company policies, or let me know if any additional steps are required.
Express Gratitude and Close Professionally
Ending your sick leave application with a polite and appreciative closing leaves a positive impression. Expressing gratitude shows professionalism and respect for the recipient’s time in reviewing your request.
A strong closing should include:
- A brief thank-you statement for considering your leave request.
- A professional closing phrase to wrap up the email or letter.
- Your name and designation (if applicable) for formal identification.
Examples of Professional Closings:
- Thank you for your time and consideration. I appreciate your support.
- I appreciate your review of my request and look forward to your response.
- Thank you in advance for considering my request. Please let me know if you need any further details.
- I understand this may require adjustments, and I truly appreciate your time and understanding.
For a formal letter, use professional sign-offs:
- Best regards,
- Sincerely,
- Thank you,
- Kind regards,
