Sick leave email to manager: what you need to know and how to get a certificate

A sick leave email to your manager is a short written notice that you are too unwell to work, sent on the day you fall ill or as early as you can. The email records when you told your employer, which dates you will miss and who covers your tasks.

The email is not medical proof.

Proof comes from a sick leave certificate, a document from a doctor stating that you were assessed and were unfit for work or study on set dates. The certificate does not decide whether your employer approves paid leave.

On the DrCertificate form, the matching choice is the Medical Certificate Sick Leave option for university or work. A work from home certificate is different, because it says you can work but should not travel to the office. A medical fitness certificate says you are fit for work, study or sport.

Your employer, school or airline decides whether to accept a sick leave certificate, not DrCertificate and not the doctor. Each organisation judges an online certificate against its own internal leave rules. Checking those rules first saves you paying for a document HR will not take.

Ask before you apply, not after.

A certificate gets questioned for a handful of common reasons. The type may be wrong, the dates may not match your email, the name may differ from company records, or the policy may only accept notes from a company clinic.

If HR questions your certificate, ask in writing which detail is the problem and whether another document would satisfy the policy. Point them to the doctor details on the certificate. Once issued, a certificate cannot be corrected unless the fault came from the medical team. Keep your reply calm and factual, and arrange an in person clinic note if HR insists.

DrCertificate serves people in ten South East Asian countries, each listed below with its own guide. Sick leave and fitness rules differ by country and by employer, so a sick leave email that works in one office may fall short in another.

In Singapore, the Ministry of Manpower says the Employment Act requires an employee who cannot report for work to inform the employer within 48 hours and to submit the medical certificate on returning to work. In the Philippines, employers in Manila, Cebu and Davao often set their own certificate rules in company policy.

Check the official rules with your country's labour ministry or department.

Then confirm with your employer, school or airline before you apply. Ask how soon they expect the email, when the certificate is due and whether they accept online medical notes.
