A key employee hands in their notice.

At first, there seems little cause for concern. Then long-standing clients begin moving their business elsewhere. Trusted colleagues resign and follow them to a competitor. Confidential information appears to have left the business alongside the departing employee.

For many employers, the greatest commercial threat is not a competitor itself, but a competitor hiring the wrong employee.

This is where restrictive covenants can become crucial.

However, many businesses only discover whether their restrictive covenants are effective when they need to enforce them, and by then, it may already be too late.

What Are Restrictive Covenants?

Restrictive covenants are contractual clauses designed to protect a business after an employee leaves.

They are commonly included within employment contracts and are intended to safeguard valuable business interests such as customer relationships, confidential information, workforce stability and goodwill.

Common examples include:

• Non-solicitation clauses preventing former employees from approaching customers or clients.
• Non-dealing clauses preventing them from conducting business with former clients.
• Non-poaching clauses restricting attempts to recruit former colleagues.
• Confidentiality provisions protecting sensitive business information.
• Non-compete clauses restricting work for competing organisations for a specified period.

For businesses that rely heavily on customer relationships, specialist knowledge or key personnel, these protections can be particularly important.

The Biggest Myth About Restrictive Covenants

One of the most common misconceptions is that a restrictive covenant is automatically enforceable simply because an employee signed the contract.

That is not the case.

Under English law, restrictive covenants must be reasonable and no wider than necessary to protect a legitimate business interest. If a restriction goes too far, a court may refuse to enforce it.

When assessing enforceability, courts may consider factors such as:

• The employee's seniority and role.
• Access to confidential information.
• Influence over customers and clients.
• The geographical scope of the restriction.
• The duration of the covenant.
• The nature of the industry and market.

A restriction that may be reasonable for a senior director with significant client relationships could be entirely unenforceable for a junior employee.

This is why professionally drafted, role-specific restrictive covenants are often far more effective than generic clauses applied across an entire workforce.

Why Restrictive Covenant Disputes Are Increasing

The modern workplace has transformed how employees build and maintain professional relationships.

Hybrid working, remote working and social media platforms such as LinkedIn have blurred traditional boundaries between personal and business connections.

Questions frequently arise such as:

• Does connecting with former clients on LinkedIn amount to solicitation?
• Can a departing employee announce their new role online?
• When does networking become a breach of contract?
• What constitutes misuse of confidential information in a digital environment?

These issues regularly lead to disputes between employers and former employees.

In many cases, the evidence is no longer found in filing cabinets or office records but in emails, messaging platforms, mobile devices and social media activity.

Warning Signs Employers Should Not Ignore

Employers are often alerted to potential breaches after damage has already occurred.

Warning signs may include:

• A sudden increase in employee resignations within a particular team.
• Customers unexpectedly moving their business to a competitor.
• Unusual downloading, forwarding or transfer of company information before departure.
• Increased contact between the departing employee and clients shortly before resignation.
• Social media activity targeting former colleagues or customers.

Spotting these warning signs early can help preserve evidence and strengthen a business's position should legal action become necessary.

Why Acting Quickly Matters

When restrictive covenant breaches are suspected, delay can be costly.

Every day that passes may allow a former employee to strengthen relationships with customers, recruit key employees or continue using confidential information.

Prompt legal advice can help employers:

• Assess whether restrictions are enforceable.
• Preserve important evidence.
• Identify potential breaches.
• Communicate with former employees and competitors.
• Consider urgent court action where appropriate.

In some situations, employers may seek an injunction from the High Court.

An injunction can prevent a former employee from:

• Soliciting customers.
• Dealing with former clients.
• Recruiting colleagues.
• Misusing confidential information.
• Working for a competitor in certain circumstances.

For many businesses, an injunction is the most valuable remedy available because it aims to stop commercial damage before it occurs, rather than attempting to recover losses afterwards.

However, injunction applications are often highly time-sensitive. Delays can seriously undermine an employer's prospects of obtaining urgent relief.

Frequently Asked Questions About Restrictive Covenants

Are restrictive covenants legally enforceable?

Yes, but only where they are reasonable and designed to protect a legitimate business interest. Courts will not enforce restrictions that go further than necessary.

How long can a restrictive covenant last?

This depends on the circumstances. Many restrictions last between three and twelve months, although enforceability always depends on the employee's role and the nature of the restriction.

Can an employee contact former clients on LinkedIn?

Potentially. Whether this amounts to solicitation depends on the facts of the case, the employee's conduct and the wording of the restrictive covenant.

What should an employer do if they suspect a breach?

Seek legal advice immediately. Early action can be critical in preserving evidence and exploring available remedies, including injunctive relief.

Can a competitor be liable for inducing a breach of restrictive covenants?

In some circumstances, yes. A competitor that knowingly encourages an employee to breach enforceable contractual obligations may face legal claims.
