Restraint of Trade Clause: Questions to Ask Before You Sign

Key takeaways

• Do not sign a restraint of trade clause on the assumption that it is automatically invalid in South Africa. The starting point established by the Supreme Court of Appeal is that a restraint agreement is enforceable unless enforcement would be unreasonable and contrary to public policy. Whether a particular restriction should be enforced depends on its wording and the facts, including the employer's protectable interest, the threat to that interest, the employee's interest in remaining economically active, wider public policy, and the restriction's duration, geographical reach and practical effect.
• That does not mean every signed restraint will be enforced. An employer may protect a genuine proprietary interest, such as qualifying confidential information or a customer connection developed in circumstances capable of harming that interest. It may not use a restraint merely to eliminate ordinary competition or prevent an employee from applying general skills and experience. The enquiry is fact-specific and is ordinarily made in the circumstances that exist when enforcement is sought.
• Before signing, identify exactly which future roles, activities, customers, territories and periods the clause restricts. Separate the restraint from confidentiality, non-solicitation, intellectual-property, notice and garden-leave terms. Test realistic future-job scenarios, ask what interest each restriction protects, propose narrower wording where needed, and keep the signed version and negotiation record.

The legal starting point is more balanced than “valid” or “invalid”

Section 22 of the Constitution protects every citizen's right to choose a trade, occupation or profession freely, while allowing the practice of a trade, occupation or profession to be regulated by law. Contractual autonomy and the principle that agreements should be honoured also form part of public policy. South African restraint cases balance these interests rather than applying a rule that always favours one side.

In Magna Alloys and Research (SA) (Pty) Ltd v Ellis, the Appellate Division rejected the former approach that treated restraints as prima facie invalid. A party seeking to avoid enforcement must establish that the restraint is unreasonable and therefore contrary to public policy.

In Basson v Chilwan, the court framed questions that remain central to the assessment:

1. Does one party have an interest deserving protection after the relationship ends?
2. Is that interest threatened by the other party?
3. If so, does the protected party's interest weigh qualitatively and quantitatively against the other party's interest in being economically active and productive?
4. Is there another aspect of public policy that requires the restraint to be maintained or rejected?

Reddy v Siemens Telecommunications (Pty) Ltd applied this framework with the Constitution in view. It also confirms that reasonableness is assessed with reference to the circumstances prevailing when enforcement is sought. A careful pre-signing review must therefore examine both the words signed today and the plausible employment facts that may exist when the employee later moves.

The result cannot be reduced to a fixed safe duration or radius. A restriction may be narrow on paper but severe in a specialised market, or broad in kilometres but practically irrelevant to a role performed only in one client segment. Job level, access, influence, sector structure, location, customer contact, information lifecycle, bargaining circumstances and the proposed new work can all matter.

Start with the restraint-of-trade glossary for the short definition. This page owns the detailed pre-signing review and negotiation decision.

Do not confuse signature risk with certain enforcement

Two mistakes create avoidable risk.

The first is treating the clause as meaningless. Signature creates a contractual record. If the employee later joins a competitor, serves a customer or starts a business, the employer may demand undertakings or seek urgent court relief. Even a defensible employee can face compressed deadlines, affidavit evidence, legal cost and commercial disruption.

The second is treating the employer's wording as conclusive. A clause saying that every item is confidential does not make ordinary public knowledge a trade secret. A clause covering every customer does not prove that the employee had a protectable relationship with all of them. An acknowledgement that the restriction is reasonable is relevant contractual evidence, but it does not remove the court's public-policy enquiry.

Pre-signing review is not a yes-or-no certification. Its purpose is to understand the promise, reduce unnecessary breadth and preserve the parties' purpose.

Map every restriction before debating reasonableness

Do not review only the paragraph headed “restraint of trade”. Definitions, schedules and cross-references may expand it. Create a clause map that records the following:

Also read any warranty that the employee has received independent advice, considers the restraint reasonable, has disclosed outside interests, or accepts that damages would be inadequate. Do not sign an acknowledgement that is factually untrue. If advice was not received, the wording should not say that it was.

Use the written particulars of employment glossary to distinguish the restraint from the wider employment terms that should be recorded and reviewed.

Ask what protectable interest the employer actually has

A restraint is not justified merely because the employer dislikes competition. The employer should identify a proprietary interest that the proposed conduct could harm.

Confidential information and trade secrets

The relevant questions are practical:

• What information will the employee receive because of this role?
• Is it genuinely confidential rather than public, stale or generally known in the industry?
• Does it have commercial usefulness to a competitor?
• How is access limited and confidentiality maintained?
• How quickly will the information lose value?
• Can the risk be addressed by non-use, non-disclosure, return and deletion duties instead of stopping work altogether?

Examples may include non-public pricing, customer terms, product roadmaps, tender strategy, source code, technical processes or planned transactions. Inclusion in a list does not decide the issue; content, access, controls and usefulness at the relevant time still require proof.

MSA Outsourcing Solutions (Pty) Ltd v Strydom, decided by the Labour Court in 2025, illustrates the importance of evidence. The court found no protectable interest where low-level employees had not acquired confidential information useful to the competitor or customer connections capable of harm. It reiterated that a restraint is not a device for suppressing competition and that an employee's skills and experience are not the employer's property. That result was based on its evidence; it is not a rule that junior employees can never be restrained.

Where ownership of work product matters, review the intellectual-property glossary. Intellectual-property allocation, confidentiality and post-employment competition are related but legally distinct questions.

Customer and trade connections

A customer list alone does not establish a protectable connection. The employee's contact and influence, and their capacity to affect the employer's relationship, require evidence.

The Labour Appeal Court's 2025 decision in Torrente v Grant Monaghan & Associates Incorporated emphasises a factual enquiry. Relevant considerations include duties, the frequency and duration of contact, knowledge of customer requirements and the relationships built. Before signing, determine whether the restriction follows actual relationships or reaches people the employee will never serve.

Ask whether “customer” includes a person who made one enquiry, appeared in a database, bought from another division, stopped buying years ago, or is merely a prospective lead. Ask whether the employee must know, influence or have material dealings with the person before the restriction applies. A defined look-back period and connection threshold can make the promise more intelligible.

Workforce, suppliers and strategic relationships

Some clauses also restrict recruiting employees or dealing with suppliers and partners. These interests should not be assumed to be identical to customer goodwill. Identify the relevant people, the employee's influence, the conduct prohibited, and whether ordinary non-solicitation wording would address the risk without prohibiting all contact or employment.

Test scope against the role the employee is accepting

The title on a job offer is not enough. Ask for a realistic description of responsibilities, accounts, systems, information and territories.

Restricted work

Does the clause prevent working for a named competitor, any competitor, any business with an overlapping product, or any person who could compete in future? Does it prohibit only the same function, or every role from chief executive to an unrelated support position? A role-based limitation may better correspond with the knowledge or influence the employer says it must protect.

Test indirect wording. Restrictions on being “interested”, “concerned”, “associated”, “engaged” or “financially involved” may reach contracting, advisory work, board service, shareholding or financing. Ask for ordinary passive investments below a defined threshold to be excluded where appropriate.

Duration

There is no universally reasonable number of months. Compare the proposed period with the information's useful life, customer-cycle length, project horizon, replacement or handover period, and the employee's realistic time to re-enter the market. Ask when the clock starts and whether garden leave, paid notice or delay in enforcing the clause affects it.

The 2023 Labour Appeal Court decision in Beedle v Slo-Jo Innovation (Pty) Ltd demonstrates why duration and proportionality require close attention, including whether a less restrictive measure can protect the interest. It should not be converted into a fixed-duration formula for unrelated jobs.

Geography and market

“South Africa”, “Africa”, “worldwide” or a kilometre radius has meaning only when compared with the employer's business, the employee's activities and the proposed competitor. For digital products and remote work, a map may be a poor proxy for the actual market. Ask which customers, revenue, service capability and employee responsibilities justify each territory.

Cascading alternatives and severability

A contract may list alternative durations, territories or activities so that a court can enforce a narrower combination. Do not assume the broadest version is harmless because another option appears below it. Understand every promise and obtain advice on the severability wording and current case law. A negotiation should aim for a clause the parties can actually administer, not a catalogue of increasingly smaller restrictions designed for later litigation.

Run future-job scenarios before signing

Test plausible future moves against the exact definitions, including roles the employee does not currently plan to take.

Classify each result as prohibited, permitted, unclear or dependent on consent. Unclear wording is a reason to clarify the contract before accepting the offer.

Separate the restraint from connected clauses

Confidentiality

A confidentiality clause controls use or disclosure of protected information. A restraint controls specified competitive activity even where misuse has not yet been proved. Ask whether a targeted confidentiality obligation, security control or deletion certification can address some risks more precisely.

Avoid definitions that permanently treat all workplace information as secret. Public information, general skill and experience, lawfully obtained third-party information and independently developed material may require exclusions. The wording should reflect information lifecycles rather than promise one result for every category.

Non-solicitation and non-dealing

Non-solicitation generally targets active approaches; non-dealing language may prohibit accepting business even if the customer initiates contact. Check which is used. Define the protected group, required prior connection, look-back period and prohibited conduct. Decide how general advertising, public job announcements and unsolicited contact will be treated.

Intellectual property

An intellectual-property clause allocates rights in work outputs. Check the legal setting, scope of employment, pre-existing materials, side projects, moral rights and disclosure duties. Ownership of qualifying work is not ownership of the employee's general ability.

Notice, garden leave and restraint payment

Notice determines when employment ends and what duties continue. Garden leave may keep employment alive while the employee is instructed not to work or contact clients. A separate restraint usually begins when the defined trigger occurs. Map whether periods overlap or run consecutively and whether remuneration continues.

South African law does not make payment an automatic prerequisite for every restraint. If the employer offers a restraint allowance, sign-on amount or continued payment, record its purpose, tax treatment, repayment terms and effect on termination. Payment does not by itself make unreasonable wording enforceable, and absence of payment does not by itself invalidate the clause.

Return, deletion and security

Clarify how devices, credentials, documents, backups, cloud storage, contact exports and personal portfolios will be returned or deleted. Do not solve a future evidence problem by secretly retaining employer documents.

Questions to negotiate rather than accept as assumptions

A negotiation can target the clause's mechanics without denying the employer's legitimate interests. Depending on the role, proposals may include:

• limiting the restriction to functions materially similar to those actually performed;
• naming the competing product or service category more precisely;
• limiting customers to those with whom the employee had material personal dealings during a defined look-back period;
• excluding divisions, territories or product lines the employee did not serve;
• aligning duration with the useful life of information or relationship cycle;
• replacing a work prohibition with confidentiality, non-solicitation, non-dealing or security obligations where adequate;
• excluding ordinary professional skill, experience and public information;
• excluding a small passive shareholding in listed investments;
• requiring written reasons and a prompt decision if consent for a future role is requested;
• defining the effect of retrenchment, employer breach or termination without fault;
• recording any restraint payment and what happens if the employer waives enforcement;
• preventing unilateral expansion when the employee changes role, territory or group company; and
• requiring a fresh review if promotion or system access materially changes the protected-interest profile.

The employer may reject some changes. The employee can then compare the role's benefit with the documented risk. Avoid side assurances such as “we never enforce these” or “HR says it only applies to sales”. If the assurance matters, ask for it to be reflected in the signed agreement by an authorised person.

Use the employment-contract service page when the restraint must be assessed within the contract as a whole rather than in isolation.

Build a clean signing record

Keep one controlled file containing:

1. the dated offer and every contract version;
2. the job description, reporting line, territory and expected accounts;
3. the restraint and confidentiality schedules;
4. the employer's explanation of the protected interest;
5. questions submitted and written responses;
6. tracked amendments and the reason for material compromises;
7. any consent, carve-out, disclosure or side-project approval;
8. proof of independent advice actually received;
9. the final complete signed agreement; and
10. a list of annexures incorporated by reference.

Preserve the contract and lawful negotiation material, not employer confidential information. If a dispute arises, obtain evidence through proper channels.

Before signing electronically, download the final version and verify that schedules, initials, signatures and dates correspond. A platform confirmation alone may not show the exact text accepted. If the employer changes the role or asks for a new restraint after employment starts, treat it as a new decision: compare versions, identify the proposed consideration or benefit, and obtain advice on the circumstances rather than assuming the first review still applies.

Independent advice helps, but does not guarantee the result

Independent advice can identify ambiguity, propose narrower language and expose conflicts between the offer, incentive plan, shareholder agreement, confidentiality undertaking and restraint.

The 2026 Western Cape High Court decision in Allens Meshco (Pty) Ltd v Krige is a fact-specific reminder that bargaining circumstances can matter. The court considered, among other things, a senior employee who used a competing offer in negotiations, received independent advice, signed voluntarily and had access to confidential information. It is not authority that advice automatically makes every restraint reasonable or that refusal to obtain advice makes a restraint invalid.

Similarly, Equity Medical Technologies (Pty) Ltd v De Villiers, decided by the Gauteng High Court in 2026, illustrates a court considering narrower restraint relief alongside continuing confidentiality obligations. The result belongs to its contract and evidence. It does, however, reinforce the need to separate the interests and remedies rather than treating every protection as one indivisible ban.

A lawyer instructed by the employer does not act independently for the employee. Establish who the adviser represents before relying on a joint explanation.

Plan for departure while joining

A sensible joining process separates personal and employer accounts, uses approved storage and records authorised side projects and pre-existing intellectual property.

When departure later becomes realistic:

• retrieve the signed contract and all amendments;
• obtain the proposed new role description before making assurances;
• compare products, functions, customers, systems, territory and information exposure;
• stop informal exports, forwarding and copying;
• follow return, deletion, handover and access-control procedures;
• document any employer waiver or consent through an authorised person;
• coordinate notice, garden leave and the proposed start date; and
• obtain advice before giving a broad undertaking or disclosing the new employer's confidential plans.

A future disagreement may involve a contractual breach-of-contract allegation, but enforcement procedure and labour-law jurisdiction need their own analysis. Do not wait for the first court papers to reconstruct the employment record.

Treat an enforcement threat as urgent

An employer may send a demand seeking undertakings, information, delivery-up or confirmation that the new role will not proceed. It may then seek urgent interdictory relief. Court timetables can be short, and the evidence is usually assembled through affidavits.

If a threat arrives:

1. preserve the demand, contract, email headers and delivery time;
2. do not delete or alter devices, messages or files;
3. stop accessing employer systems after authority ends;
4. do not send an improvised admission or promise;
5. preserve the new role description and communications relevant to scope;
6. identify the customers, information and activities actually involved;
7. tell the proposed employer about the legal process through an appropriate channel; and
8. obtain urgent advice before the response or court deadline.

Do not publish the dispute on social media or contact customers to build support. Do not assume resignation, dismissal, retrenchment or alleged employer breach automatically cancels the restraint. The agreement, termination facts, public policy and relief sought must be assessed together.

Eighteen questions to ask before signing

Ask the employer, recruiter or independent adviser:

1. What exact proprietary interest is each restriction intended to protect?
2. Which information will this role receive that is not public or ordinary industry knowledge?
3. How long is that information expected to remain commercially useful?
4. Which customers, prospects, suppliers or employees can fall within the clause?
5. Must I have had material dealings or influence before a relationship is protected?
6. Which products, services and businesses count as competitors?
7. Does the restriction follow my actual function or prohibit every role at a competitor?
8. Which territories correspond with the work I will actually perform?
9. When does the restricted period begin, and does notice or garden leave overlap?
10. Does the clause apply after resignation, dismissal, retrenchment and employer breach?
11. Are passive investments, existing interests and approved side projects excluded?
12. How do confidentiality, intellectual-property, non-solicitation and non-dealing duties differ?
13. Could narrower confidentiality or relationship protections address the stated risk?
14. Is any restraint payment offered, and what repayment or waiver terms apply?
15. Who may consent to a future role, on what information, and within what period?
16. Will promotion, transfer or expanded access require a new review?
17. What records will show the agreed purpose, role and negotiated limits?
18. At what point should an independent labour lawyer review the complete contract?

When legal review is proportionate

Obtain advice before signing where the clause is wide or unclear; the role is senior, specialised or customer-facing; the employee will access valuable non-public information; the employer operates across several territories or group companies; the offer conflicts with an existing restraint; equity, sale-of-business or shareholder documents add another restraint; the employee is leaving a competitor; the clause applies regardless of employer-initiated termination; the role is the employee's principal field of expertise; or the commercial value of the offer does not justify unmeasured mobility risk.

Urgent advice is warranted after a demand, request for undertakings, device-preservation notice or court papers; where a start date is imminent; where the old and new employer disagree about the role; or where confidential information may have been copied, retained or exposed.

A lawyer cannot guarantee a decision on hypothetical future facts. A useful review produces a clause map, risk assessment, proposed wording and decision record.
