'It's The Law' – Restraint of trade

When you are running a business, it is a good idea to consider how your business would be affected if a key employee moves on and how best to protect yourself from the negative impact of the departure.

But how do you do that, and, if you are an employee, what does that mean for you?

Businesses can protect their interests by including restraint-of-trade clauses in employee contracts.

For employees, this means knowing from the outset what the conditions are if they move on and ensuring the employment agreement they enter into is fair.

Restraint of trade clauses commonly include confidentiality and non-compete clauses. 

A confidentiality clause prevents an employee from disclosing or using the business’s information in another business, while a non-compete
prevents an employee from entering or starting a similar profession or trade in competition with the business, as their former employer. 

The effectiveness of these clauses depends on the individual circumstances. 

In considering whether to enforce the restraint-of-trade clause, the courts will weigh up a number of competing interests. 

This includes the employer’s interests in protecting confidential information, customer connections and other legitimate business interests, plus the employee’s ability to earn a living using their skills, experience and know how, along with the public interest in freedom of trade and competition. 

Many restraint clauses are void due to the unreasonable nature or scope of the clause.

To be upheld, the clauses must be shown to protect an employer’s legitimate interest, that it does so reasonably and that the enforcement of the clause would not be contrary to the public interest. 

This assessment is based on the situation when the contract was entered into, including the activities restrained, duration and geographical area covered by the clause. 

For example, if a clause seeks to stifle competition, it typically will not be enforced. Rather, the business needs to be able to identify a specific business interest which reasonably requires the protection of the restraint clause. 

Other important considerations include an employee’s skill and experience, whether information is, in fact, confidential, and whether the parties were on an equal footing in negotiating the provisions. What is considered reasonable will vary according to the circumstance.

There is one other way a restraint-of-trade or post-employment restraint could be considered by the court. It might be found that the clause seeks to protect a legitimate interest, but the terms are too broad. In this instance, a court might seek to save part of the clause by severing invalid parts. This ruling can only occur if the court can remove the invalid parts, leaving a clause that is self-contained and enforceable. 

The process of enforcing a restraint of trade can involve initiating urgent court proceedings to obtain an injunction  – a type of court order – prohibiting the employee from undertaking the activity identified in the restraint. 

As a business owner seeking to protect your interests, restraint clauses can offer some protection. 

However, the wording of the clauses and scope is important. 

Seeking legal advice can help ensure they could be upheld in court.

If you are an employee, consider the clauses included in your employment contract. They could mean serious restriction of your future occupational opportunities. 

On this basis, you might wish to seek independent legal advice prior to signing.
