Common Mistakes

Forgetting to mention the expected return date, missing the medical certificate submission deadline, and failing to arrange a handover for urgent work.

Professional Writing Tips

A calm, factual tone works best. There is no need for elaborate explanations - just the key details the employer needs.

Medical Certificate Requirements

When Required

Most companies require a medical certificate once the absence crosses a defined threshold, commonly 1 or 2 days.

What It Should Include

The certificate should typically state the diagnosis or nature of the illness, the recommended rest period, and be issued by a licensed medical practitioner.

Employer Expectations

Employers generally expect the certificate to be submitted promptly upon the employee's return to work, or within a specified number of days.

HR Best Practices for Medical Leave Requests

Maintain a clear, consistent approval process, protect the privacy of medical information shared by employees, store medical records securely, define return-to-work procedures where relevant, consider fitness certificates for certain roles or extended absences, and ensure accurate payroll processing for the leave period.
