In today’s competitive business landscape, employers often include restraint of trade clauses in employment contracts to protect their legitimate business interests. These clauses are designed to restrict employees from engaging in certain activities, such as competing with their former employer or soliciting clients or employees, for a specified period of time after the termination of their employment. However, enforcing restraint of trade clauses can be complex and challenging under South African law. In this article, we will explore the key considerations and best practices for successfully enforcing restraint of trade in South African law.

Restraint of trade clauses are recognized and regulated under South African common law and are also governed by the Competition Act, No. 89 of 1998, which prohibits anti-competitive behavior. These clauses are considered prima facie unenforceable as they are regarded as restraints on trade, which is against public policy. However, restraint of trade clauses may be enforceable if they are reasonable and protect a legitimate proprietary interest of the employer, such as trade secrets, confidential information, or customer relationships.

One of the most critical factors in successfully enforcing restraint of trade in South African law is the reasonableness of the clause. Restraint of trade clauses must be reasonable in terms of the duration, geographical scope, and the activities restricted. The reasonableness of the clause is assessed based on the specific circumstances of each case, including the nature of the employer’s business, the employee’s position and responsibilities, and the legitimate interests the employer seeks to protect.

Duration: The duration of the restraint of trade clause should be reasonable and not excessively long. The courts generally consider periods of one to two years as reasonable, although longer periods may be justified in exceptional cases. However, if the duration is too long, the court may refuse to enforce the clause.

Geographical Scope: The geographical scope of the restraint of trade clause should be reasonable and limited to the areas where the employer has legitimate interests. For example, if the employer only operates in a specific region, it may not be reasonable to restrict the employee from working anywhere in the country or globally. The courts will consider the nature of the employer’s business, the employee’s position, and the geographic area necessary to protect the employer’s interests.

Restricted Activities: The activities restricted by the restraint of trade clause should be reasonable and directly related to the legitimate interests of the employer. For example, if the employer seeks to protect its customer base, it may be reasonable to restrict the employee from soliciting clients or engaging in similar business activities. However, the clause should not unreasonably prevent the employee from earning a living or pursuing a legitimate career.

In addition to reasonableness, the enforcement of restraint of trade clauses also requires the employer to demonstrate a legitimate proprietary interest that needs protection. This may include trade secrets, confidential information, or customer relationships that are valuable and unique to the employer’s business. The employer must also show that the restraint of trade clause is necessary to protect these interests and that there are no less restrictive alternatives available.

When seeking to enforce restraint of trade clauses, the employer must follow the proper legal procedures. The employer should provide the employee with a copy of the restraint of trade clause and notify them of their obligations under the clause. If the employee breaches the restraint of trade clause, the employer may need to take legal action to enforce it.

The first step in enforcing a restraint of trade clause is to seek an interdict from the court. An interdict is a court order that prohibits the employee from engaging in the activities restricted by the restraint of trade clause until the court has made a final determination on the enforceability of the clause.
