Medical certificates and sick notes

Medical certificates, commonly known as sick notes, play an important role in managing sick leave in the workplace. They serve as proof that an employee was unable to fulfil their normal work duties due to illness or injury. Although most employees and employers are familiar with the concept of a sick note, there is often uncertainty regarding when one may be required, what information should appear on it and how to determine its validity.

What legislation stipulates regarding sick notes

In terms of Section 23 of the Basic Conditions of Employment Act 75 of 1997 (BCEA), an employer cannot require a sick note for every day of absence. The act stipulates that an employee is only obliged to submit a medical certificate if the employer requests it and he/she:

• has been absent from work for more than two consecutive days due to illness or injury; and/or
• has been absent due to illness or injury on more than two occasions during an eight-week period, even if the employee is absent for only one day.

In such instances, the employer may lawfully require proof of the employee’s incapacity for work.

A valid medical certificate

A medical certificate is valid only if it has been issued and signed by a medical practitioner or other health practitioner who is legally registered with an appropriate professional council. This requirement protects both the employee and the employer and ensures that the necessary sick leave is based on the professional opinion of a qualified person.

The BCEA does not specify all the information that must appear on a sick note, but the Health Professions Council of South Africa (HPCSA) sets guidelines with which practitioners must comply. The medical certificate should contain the following information:

• the practitioner’s name, address, qualification and registration number, as well as their initial and surname in block letters
• the patient’s name and employee number (if applicable)
• the date and time of the examination
• the date and basis on which the certificate was issued
• a description of the illness or ailment in layman’s terms (with the patient’s consent)
• whether the patient is completely unfit for duty or can perform lighter work
• the exact period of the recommended sick leave

Disclosure of the diagnosis

An important aspect that is often misunderstood is the disclosure of the employee’s diagnosis. The BCEA does not require the specific medical condition or diagnosis to be indicated on the certificate. Medical information is considered private and confidential and is protected under the employee’s right to privacy. Therefore, it suffices if the certificate merely states that the employee was unfit for work due to a “medical condition” or “medical reasons.” Employers should respect this principle of confidentiality and not attempt to gain unnecessary access to sensitive medical information.

Investigate the validity

However, this does not mean that an employer is obliged to accept a medical certificate blindly. If there are reasonable grounds to question the authenticity or validity of the document, the employer may conduct an investigation. Such investigations may include verifying the practitioner’s registration with the relevant professional council, confirming the date of the consultation, or confirming the period for which the employee was booked off.

However, there are clear limits to such inquiries. Employers may not make inquiries regarding the employee’s diagnosis or any other confidential medical details without the employee’s consent. The purpose of the inquiry is solely to determine the validity of the medical certificate and not to gain access to private health information.

Medical certificates therefore fulfil an important function in the employment relationship. They protect employees who are genuinely ill and ensure they are treated fairly, while enabling employers to manage absenteeism effectively and address potential abuse of sick leave. When both parties understand the legal requirements and rights, it contributes to a professional, productive and fair working environment.
