Sick Note Requirements in South Africa: The BCEA and HPCSA Rules

Updated 2026-07-05 · Written for South African healthcare practitioners by Sphygmos.

Every practising doctor and every employer in South Africa runs into the same question: what makes a sick note valid? The answer sits in two places. Section 23 of the Basic Conditions of Employment Act 75 of 1997 (BCEA) governs when an employer may insist on a medical certificate before paying sick leave and who may issue one. Rule 16 of the HPCSA's Ethical Rules of Conduct prescribes exactly what a certificate of illness must contain. This guide sets out both in plain language, together with the backdating rules and the errors that most often get certificates rejected.

When may an employer demand a sick note?

Start with the entitlement. Under section 22 of the BCEA, an employee is entitled, during each sick leave cycle, to paid sick leave equal to the number of days the employee would normally work during six weeks. A sick leave cycle is 36 months of employment with the same employer, so an employee on a five-day week has 30 days of paid sick leave per cycle and an employee on a six-day week has 36. During the first six months of employment the entitlement is one day's paid sick leave for every 26 days worked.

The certificate question is, strictly, a payment question. Section 23(1) provides that an employer is not required to pay an employee for sick leave if the employee has been absent from work for more than two consecutive days, or on more than two occasions during an eight-week period, and, on request by the employer, does not produce a medical certificate stating that the employee was unable to work for the duration of the absence on account of sickness or injury.

Two practical consequences follow. A one- or two-day absence ordinarily needs no certificate before sick pay is due — but a single day off can still trigger the requirement if it is the employee's third occasion of absence inside eight weeks. And the certificate must be requested by the employer and must cover the full duration of the absence.

Absence of more than two consecutive days: the employer may request a certificate before paying sick leave.
Absence on more than two occasions in any eight-week period: even single-day absences count as occasions.
Employees living on the employer's premises: under section 23(3), if it is not reasonably practicable for such an employee to obtain a certificate, pay may not be withheld unless the employer provides reasonable assistance to obtain one.

Who may lawfully issue a medical certificate?

Section 23(2) of the BCEA sets a two-part test: the certificate must be issued and signed by a medical practitioner, or by any other person who is certified to diagnose and treat patients and who is registered with a professional council established by an Act of Parliament. Both legs must hold. Registration with a statutory council is not enough on its own if the person's registered scope does not include diagnosing and treating patients.

In practice that covers practitioners registered with the Health Professions Council of South Africa (HPCSA) — including medical practitioners, dentists and psychologists — as well as professional nurses registered with the South African Nursing Council whose scope of practice permits assessment, diagnosis and treatment, practitioners registered with the Allied Health Professions Council of South Africa, and traditional health practitioners registered under the Traditional Health Practitioners Act. The common thread is a statutory register that the employer can check.

What fails the test: certificates completed or signed by reception staff on the practitioner's behalf, rubber-stamped notes without a personal signature, and notes from anyone who is not on a statutory professional register. The BCEA's wording is deliberate — issued and signed by the practitioner.

What a valid certificate must contain: HPCSA Rule 16

For HPCSA-registered practitioners, Rule 16 of the Ethical Rules of Conduct (the generic ethical rules published under the Health Professions Act) prescribes the content of a certificate of illness. A practitioner may only grant a certificate that contains all of the following:

The practitioner's name, address and qualification
The name of the patient
The patient's employment number, if applicable
The date and time of the examination
Whether the certificate is issued on the practitioner's personal observations during an examination, or on information received from the patient that is based on acceptable medical grounds
A description of the illness in layman's terms, given only with the patient's informed consent — if the patient withholds consent, the certificate states only that, in the practitioner's opinion based on an examination, the patient is unfit to work
Whether the patient is totally indisposed for duty, or able to perform less strenuous duties in the work situation
The exact period of recommended sick leave
The date the certificate was issued
The practitioner's initials and surname in block letters, together with their registration number, next to a personal signature

Signature, stationery and the registration number

Two Rule 16 details are routinely missed. The certificate must be signed by the practitioner personally, next to their initials and surname printed in block letters — a stamp or a staff member's signature does not satisfy the rule. And where pre-printed certificate stationery is used, the words that do not apply must be deleted; leaving contradictory pre-printed options standing is itself a defect.

Note the distinction between numbers. The ethical rule requires the practitioner's registration number — the number under which the practitioner appears on the council's register. A practice (billing) number on the letterhead is useful for accounts, but it does not substitute for the registration number on the certificate.

Backdating and the 'informed that the patient was ill' wording

Rule 16 draws a firm line between two dates: the date and time of the examination, and the date the certificate was issued. Both appear on the certificate and both must be true. Writing a false date of issue so that a certificate appears to have been produced earlier than it was is falsification, and no version of it is permitted.

What the rules do allow is retrospective coverage with an honest basis. A doctor who first sees a patient after the illness began may certify the earlier period, provided the certificate discloses that it rests on information received from the patient, on acceptable medical grounds, rather than on personal observation. That disclosure requirement is the origin of the familiar 'I was informed that the patient was ill' wording.

The distinction matters to whoever reads the note. A certificate based on personal observation certifies illness the practitioner actually assessed; a certificate based on the patient's account certifies only that the account was given and was medically plausible. Employers are entitled to read the two differently, and a practitioner should never present the second as if it were the first.

Common pitfalls for doctors

These are the errors to design out of your practice — each one gives an employer, and potentially the HPCSA, a reason to query the certificate:

Certifying without disclosing the basis: a telephonic or retrospective account written up as though the patient was examined on the day
Vague durations such as 'a few days' or 'until recovered' instead of the exact period of recommended sick leave
Recording a diagnosis without the patient's informed consent — if consent is withheld, the certificate may state only that the patient is unfit to work
Omitting the time of the examination, the registration number, or the block-letter identity next to the signature
Using pre-printed certificate pads without deleting the words that do not apply
Allowing reception or admin staff to complete, stamp or issue certificates — the BCEA requires the certificate to be issued and signed by the practitioner
Issuing certificates outside your registered scope of practice

Employer questions, answered

An employer may withhold sick pay only when the section 23(1) conditions line up: the absence exceeded two consecutive days or was the employee's third occasion within eight weeks, the employer requested a certificate, and the employee failed to produce one covering the duration of the absence.

Faced with a doubtful note, an employer is entitled to test it against the statutory requirements. Was it issued and signed by the practitioner personally? Is the issuer registered with a statutory professional council — the HPCSA and other councils keep registers that can be checked? Does it contain the Rule 16 elements, including the dates, the basis of the certificate and the exact period? A certificate that fails section 23(2) — for example, one issued by a person not registered with any statutory council — need not be accepted as proof of incapacity.

What an employer may not do is disregard the scheme. Sick pay may not be withheld for a short, infrequent absence that does not meet the section 23(1) thresholds, and an employee who lives on the employer's premises may not be denied pay for want of a certificate unless the employer gave reasonable assistance to obtain one. Suspicion of abuse is handled through verification and, where warranted, the employer's disciplinary processes — not by rewriting the BCEA.

How Sphygmos helps

Sphygmos drafts BCEA- and HPCSA-compliant sick notes in seconds. Every Rule 16 element — the date and time of examination, the basis of the certificate, the exact period of recommended leave, the practitioner's registered details in the required form — is structured into the draft automatically, and nothing is issued until the doctor has reviewed, amended and signed it. The certificate is always a draft first; the doctor is always the final gate.

Frequently asked questions

Can an employer refuse a sick note from a clinic nurse?

Not merely because it comes from a nurse. A professional nurse registered with the South African Nursing Council may issue a valid certificate if their registered scope of practice includes assessing, diagnosing and treating patients, which satisfies section 23(2) of the BCEA. An employer may, however, query a note where the issuer is not on a statutory professional register or acted outside that registered scope.

When can an employer legally demand a medical certificate?

Under section 23(1) of the BCEA, an employer is not required to pay sick leave if the employee was absent for more than two consecutive days, or on more than two occasions within an eight-week period, and fails on request to produce a medical certificate covering the absence. That means even a single day off can require a certificate if it is the third occasion in eight weeks. For shorter, less frequent absences, the BCEA does not make sick pay conditional on a certificate.

Can a doctor backdate a sick note in South Africa?

A certificate may never carry a false date: the date of the examination and the date of issue must both be accurate. A doctor who sees a patient only after the illness began may certify the earlier period, but the certificate must state that it is based on information received from the patient on acceptable medical grounds rather than on personal observation. Falsifying the date of issue is a disciplinary matter before the HPCSA.

Does a sick note have to state the diagnosis?

No. Under HPCSA Rule 16, the illness may be described in lay terms only with the patient's informed consent. If the patient withholds consent, the certificate states only that, in the practitioner's opinion based on an examination, the patient is unfit to work — and that remains a valid certificate.

Are sick notes from traditional healers valid?

The BCEA test is the same for every issuer: the person must be certified to diagnose and treat patients and registered with a professional council established by an Act of Parliament. The Traditional Health Practitioners Act provides for a statutory council for traditional health practitioners, so a certificate from a practitioner registered under it can meet that test. An employer is entitled to verify the registration before accepting the note.

How many sick leave days do employees get in South Africa?

During each 36-month sick leave cycle with the same employer, an employee is entitled to paid sick leave equal to the number of days they would normally work in six weeks — 30 days for a five-day week, 36 days for a six-day week. During the first six months of employment, the entitlement is one day's paid sick leave for every 26 days worked.

Can an employer phone the doctor to verify a sick note?

An employer may verify authenticity — whether the certificate was genuinely issued by that practice and by a registered practitioner — and may check the practitioner's details on the relevant council's public register. The practitioner remains bound by confidentiality and may not discuss the patient's condition without consent. Verification tests the document, not the diagnosis.
