Restraints of trade are common in employment contracts in South Africa, yet they remain one of the most misunderstood clauses. Employers rely on them to protect their businesses, while employees often worry about whether they are enforceable and what they mean for their future careers.
What is a Restraint of Trade?
A restraint of trade is a contractual clause that restricts an employee from competing with their former employer after leaving the job. The purpose is to protect legitimate business interests such as client relationships, trade secrets and confidential information.
For instance: if a barista resigns from a coffee shop and opens a competing shop across the street using the same methods and client contacts, a restraint of trade could prevent that.
Are Restraints of Trade Enforceable in South Africa?
In principle, restraints of trade are valid and enforceable in South Africa. The law balances two competing rights: the employer’s right to protect its business interests, and the employee’s constitutional right to freedom of trade and the ability to earn a living. The cases of Magna Alloys v Ellis and Basson v Chilwan established that a restraint is enforceable only if the employer has a protectable interest and if the clause is reasonable in scope, duration and geographic reach.
What is a Protectable Interest?
A protectable interest is more than a general desire to avoid competition. The courts have made it clear that an employer cannot use a restraint simply to eliminate an ex-employee as a rival. Instead, the employer must show that the restraint safeguards something real and proprietary. This usually includes confidential information, trade secrets, specialised know-how, unique processes, pricing structures, or valuable customer relationships developed through the employment. In other words, the restraint must protect knowledge or connections that belong to the employer, rather than merely preventing the employee from making a living through ordinary competition.
What Makes a Restraint “Reasonable”?
What is reasonable always depends on the circumstances. Courts consider factors such as the length of time for which the restraint applies, the geographical area it covers, and the type of activities that are restricted.
For instance, a clause preventing the barista from working anywhere in South Africa for a year is likely to be excessive. By contrast, a clause that prevents the barista from working within a five-kilometre radius of a previous employer for six months may well be considered reasonable, because it is narrowly tailored to protect the employer’s customer base without unduly limiting the barista’s career opportunities elsewhere.
The Burden of Proof
An important point is that a restraint of trade is presumed valid because the employee signed the contract. If an employee believes it is unenforceable, the burden rests on them to prove this in court. They must show that the previous employer has no protectable interest, and that the clause is unreasonable because it is too broad, lasts too long, or effectively prevents them from earning a livelihood in their field.
Consequences of Breach
The consequences of breaking a restraint of trade can be serious. Employers can approach the court, even on an urgent basis, to obtain an interdict preventing an employee from continuing the breach. They can also claim damages for the loss they suffered. Employees, however, are not without recourse: they can oppose enforcement by demonstrating that the restraint is unreasonable, and if the court agrees, the restraint will not be enforced. In some cases, the employer may even be ordered to pay the employee’s legal costs.
Drafting and Disputes
For employers, the drafting of a restraint of trade clause is critical. The clearer and narrower it is in terms of time, geography and activities, the more likely it will withstand scrutiny. For employees, it is important to understand the impact of any restraint before signing an employment contract, and to seek legal advice if faced with enforcement.
Conclusion
Restraints of trade can be powerful tools, but they must strike a fair balance between protecting a business and allowing an individual to make a living. Whether you are an employer seeking to safeguard your interests or an employee facing a restraint clause, legal advice and quick action are essential.
