The Briefcase That Should Not Leave: Client Information After a Key Employee Resigns

A resignation from a key member of staff is rarely just an HR event. For many small businesses, the departing employee holds relationships, pricing knowledge and a mental map of how the company actually operates. The natural reaction is to protect the business immediately. The more effective reaction is to protect it carefully.

If you suspect that a departing employee has taken client contacts, know-how or confidential information, the first priority is not accusation. It is to establish what your contracts say, what has actually happened and what response is proportionate. A measured approach is usually cheaper, faster and more credible than a loud one.

Start with the contract, not the accusation

Before taking any step that could damage the relationship or the employee’s reputation, review the employment contract, the staff handbook and any separate confidentiality or restrictive covenant agreement. Look for clauses dealing with confidential information, client contacts, solicitation, competition, intellectual property and the return of company property. If the employee is also a director or shareholder, separate duties may apply.

It is important to distinguish between different kinds of information. A client list may be confidential where it contains information not readily available to competitors, such as contact details, buying patterns, pricing arrangements or particular requirements. General industry knowledge and personal skills are usually not protected in the same way. Likewise, an employee’s personal relationships with clients are not automatically the employer’s property. The contract and the nature of the information matter.

Restrictive covenants are not automatically enforceable. A non-solicitation, non-dealing or non-compete clause must protect a legitimate business interest and go no further than is reasonable in duration, geography and scope. A clause that is too wide may be unenforceable. That does not mean it can be ignored. It means advice should be taken early, before a position is taken in correspondence.

What confidentiality clauses and garden leave actually do

A confidentiality clause generally protects information that is genuinely confidential: trade secrets, financial information, business plans, customer terms and internal know-how that is not in the public domain. It does not usually stop an employee from using general skill and experience. It also does not necessarily prevent them from working for a competitor unless a valid restrictive covenant says so.

Garden leave is a practical tool, not a punishment. Where the contract permits it, the employer can require the employee to stay away from work during notice while remaining employed and paid. The employment relationship continues, and so do the employee’s duties of loyalty and confidentiality. Garden leave can reduce the opportunity to take further information or influence clients, but it must be used consistently with the contract and without cutting pay or benefits unlawfully.

The evidence question

Before making allegations, establish the facts. Relevant evidence may include device and email audit logs, CRM access records, downloads, forwarding activity, print logs and the timing of client departures. It may also include what the employee said at exit, what was returned and whether company documents have been deleted.

Preserve evidence, but do not conduct a fishing expedition. Avoid accessing personal email accounts or personal devices unless there is a clear legal basis and proper advice has been taken. Do not review material that is legally privileged or unrelated to the concern. A forensic review should be handled carefully, with a clear scope and an audit trail. If a dispute is likely, take advice before reviewing material so that the evidence can be used properly and the business does not create a separate problem for itself.

Proportionate steps in the first few days

A calm sequence is usually best.

First, secure company access. Suspend IT accounts, remote access and building access where appropriate, but do so in line with the contract and without making a public spectacle.

Second, remind the employee in writing of their continuing obligations. Keep the tone factual. A short letter referring to confidentiality, return of property and any restrictive covenants is often more effective than a lengthy accusation.

Third, hold an exit interview and ask for confirmation of what has been returned. Record what was said. Ask for company devices, documents and login details to be returned or disabled.

Fourth, review client contact carefully. If clients are likely to follow the employee, a factual communication may be appropriate. It should not disparage the employee or make allegations that cannot be supported. Defamation and harassment risks are real, and a careless email to clients can worsen the commercial damage.

Fifth, consider garden leave if the contract allows it and the role makes it sensible. Sixth, preserve documents and correspondence. Seventh, take legal advice before sending a letter before action or applying for an injunction.

When to escalate

Court action is sometimes necessary. If there is evidence of ongoing misuse of confidential information, solicitation in breach of a valid covenant or removal of company material, a solicitor can advise on a letter before action, delivery up of documents, damages, an account of profits or urgent injunctive relief. In limited cases, springboard relief may be considered where the employee has gained an unfair head start.

But escalation should be evidence-led. A court will expect proportionality, and an employer that has behaved reasonably is in a stronger position. Mediation or a negotiated exit may be more appropriate than litigation, particularly where client relationships and staff morale are at stake.

A quiet exit is often the cheaper one

The best protection is preventative. Use clear contracts, review restrictive covenants periodically and make sure confidentiality policies are actually understood. Conduct exit interviews consistently. Remind departing staff of their obligations without treating every resignation as a crisis.

If a key employee leaves with more than their notice period, act promptly but carefully. Preserve evidence, check the contract and take advice before making allegations.
