Can you secretly record your boss? What South African law allows

From WhatsApp messages and emails to secret recordings and eyewitness testimony, South African employees may have more workplace evidence available than they realise. Here is what could help strengthen your case during a disciplinary hearing or employment dispute.

Imagine sitting in a stressful disciplinary hearing where it is your word against your manager’s. You know you are telling the truth about an unfair instruction or a hostile encounter, but when the chairperson asks for proof, you freeze. How do you prove what happened behind closed doors?

Many employees mistakenly believe that unless they have a signed confession or high-definition CCTV footage, they have no case. However, workplace disputes are generally determined on a balance of probabilities. In simple terms, the decision-maker weighs the evidence to determine which version of events is more probable.

To strengthen your case, it is important to understand what can constitute evidence in the workplace.

A clear paper trail can be particularly valuable evidence. Human memory can fade, but contemporaneous records can help establish what happened and when.

Documentary evidence may include company emails, signed contracts, payslips, formal policies and other workplace records.

Importantly, it can also include less formal written communications. WhatsApp messages, SMSes and Microsoft Teams chats may be used as evidence, depending on their relevance, authenticity and the circumstances in which they were obtained.

If a manager is harassing you, giving you potentially unlawful instructions or approving your leave via WhatsApp, preserve the relevant messages. Screenshots can be useful, but retaining the original messages and other information that may help establish their authenticity can strengthen your evidence. Do not assume that messages will remain accessible indefinitely, as devices can be lost and messages can be deleted.

One of the most common questions employees ask is whether they may secretly record a hostile meeting or a difficult interaction with a manager.

South Africa’s Regulation of Interception of Communications and Provision of Communication-Related Information Act, commonly known as RICA, regulates the interception of communications.

Importantly, the law allows a person who is a party to a communication to intercept that communication, subject to certain exceptions. In practical terms, if you are participating in a conversation, you may generally record it without obtaining the other participant’s consent.

That is different from leaving a hidden recording device in a room to record a conversation between other people when you are not present.

For example, if you are called into an office for a one-on-one meeting with your manager, a recording you make as a participant in that conversation may potentially be used as evidence. Its admissibility and evidential weight will depend on the circumstances.

Recordings can be particularly useful when a dispute concerns exactly what was said during a meeting or conversation.

Witness testimony can be important workplace evidence, particularly when a witness personally saw or heard the incident in question.

If a colleague testifies, “I saw the manager throw the file at him,” that is direct evidence of what the colleague says they witnessed.

If the colleague instead says, “He told me that the manager threw the file at him,” the evidence may constitute hearsay because its value depends on the credibility of someone other than the person giving the evidence.

However, hearsay is not automatically worthless or inadmissible in labour proceedings. South African law allows hearsay evidence to be admitted in certain circumstances, including where its admission would be in the interests of justice. Factors such as its reliability, probative value, purpose and potential prejudice may be considered.

Where possible, direct testimony from the person who actually witnessed an incident will generally place the decision-maker in a better position to assess the evidence and the witness’s credibility.

Polygraph, or “lie detector”, tests are sometimes used by employers when investigating misconduct such as theft or dishonesty.

However, a failed polygraph test does not, on its own, establish an employee’s guilt.

South African labour courts have held that polygraph results may be considered alongside other supporting evidence in appropriate circumstances. Factors such as the qualifications of the polygraph examiner, the manner in which the test was conducted and the availability of corroborating evidence can affect the weight attached to the results.

An employer should therefore not rely solely on a failed polygraph test as proof that an employee committed misconduct. Polygraph evidence is better understood as potentially supporting other evidence rather than replacing the need to prove the allegations against an employee.

Facing a disciplinary hearing or trying to build a case involving unfair treatment can be overwhelming, particularly when you are uncertain whether your evidence will carry legal weight.

This is where support from Legal Leaders can make a difference. Active members can access legal support when dealing with workplace disputes. Having a specialist to help you understand the evidence and the process can provide valuable guidance when navigating a difficult employment matter.

Your word matters, but evidence can strengthen your case. Start building and preserving your paper trail before you need it.
