A Key Employee Left and Took Clients. What Can My Company Do?

Start with what the employee signed

The company's position is set largely by paperwork that already exists. Pull everything the departing employee signed: the offer letter, any employment or commission agreement, a confidentiality or invention agreement, a stock or bonus plan, the handbook acknowledgment. Look for four things: a non-compete, a non-solicitation of customers, a non-solicitation of employees, and a confidentiality clause.

Each opens a different claim. A non-compete or non-solicit, if it meets the Texas test in Business and Commerce Code section 15.50, can be enforced by injunction and, when it was reasonable as written, by damages. The test and the enforcement steps are covered in how to enforce a non-compete against a former employee, and non-solicitation clauses specifically in non-solicitation agreements in Texas. A confidentiality clause is enforced as an ordinary contract, with no reformation rule and no statutory limit on damages, which is why it is often the stronger claim.

If there is no non-compete

Texas does not imply a non-compete. A former employee with no covenant may work for a competitor, may announce the move, and may do business with former clients who choose to follow. Clients are not property, and the goodwill a salesperson built is not, by itself, something the company can reclaim.

What the law does protect, even with no covenant at all:

• Trade secrets. A customer list, pricing, margins, renewal dates or account histories can qualify as trade secrets under the Texas Uniform Trade Secrets Act, Civil Practice and Remedies Code chapter 134A, and the federal Defend Trade Secrets Act, if the information has value from not being generally known and the company took reasonable measures to keep it secret. Taking that information and using it to solicit is misappropriation, whatever the employee signed. Whether a particular list qualifies is examined in can an employee take my customer list.
• The duty of loyalty while employed. An employee is an agent and owes the employer loyalty until the last day. Texas law lets an employee prepare to compete, for example by lining up a new job or forming a company. It does not let the employee solicit the company's clients for the new venture, divert opportunities, or copy files for later use while still on the payroll. Conduct in the final weeks is often where the real case lies.
• Confidentiality agreements. Nearly every company has one somewhere in its onboarding documents. It covers information that may not rise to trade secret status but that the employee agreed not to use or disclose.
• Tortious interference. If the new employer knew of a covenant and encouraged the breach, or if the former employee induced clients to break existing contracts rather than simply decline to renew, a separate claim exists.

What to do in the first week

1. Preserve everything. Do not wipe or reissue the employee's laptop or phone. Have IT image the devices and export mailbox, cloud storage and CRM activity logs for the last 90 days. Suspend auto-deletion. Put a written litigation hold on the people who worked with the departing employee.
2. Cut access. Disable every credential, including shared logins and vendor portals, and check for forwarding rules and connected personal devices.
3. Map the damage. List the clients who have left or gone quiet, the revenue involved, and the date of each contact you know of. This becomes the injury evidence for an injunction.
4. Gather the agreements and the proof of consideration. For any covenant, the company must show what it gave in exchange: confidential information, training, equity. Onboarding records and access logs prove that.
5. Hold the line with clients. Reach out to retain them with the company's own offering. Do not tell clients the former employee is a thief or acting illegally; that is how a defamation counterclaim starts.
6. Get a legal read before the first letter. The letter to the employee and the notice to the new employer set the tone of the case and can create fee exposure if they overstate a covenant.

What the evidence usually shows

The forensic review of the departing employee's accounts is where these cases are won or lost. Patterns that matter: large downloads or exports from the CRM in the final weeks, emails to a personal address with attachments, USB device connections, cloud sync of client folders, and messages to clients that read as advance notice of a move. A clean review that shows none of this narrows the case to any covenant the employee signed; a review that shows exports and pre-resignation client contact opens trade secret and loyalty claims regardless of covenants. What the company may examine, and how, is covered in investigating a departing employee's devices and accounts.

Example

Suppose a Dallas commercial cleaning company's operations director resigns with two weeks' notice, joins a competitor, and within a month six of the company's twenty largest accounts have given termination notices. He signed a confidentiality agreement at hiring but no non-compete. The company images his laptop and finds that, ten days before resigning, he exported the full account list with contract end dates and pricing to a spreadsheet and emailed it to a personal address, and that he met with three of the six clients during his notice period.

There is no covenant to enforce. But the export and pre-resignation meetings support a trade secret claim for the pricing and renewal data, a breach of the confidentiality agreement, and a breach of the duty of loyalty for soliciting while employed. The company files in Dallas County district court, obtains a temporary restraining order requiring return of the spreadsheet and barring use of the exported data, and later a temporary injunction. The six accounts are not ordered back, because clients are free to choose, but the competitor loses the pricing advantage and settles the damages claim for the diverted contracts.

Remedies the company can realistically get

A court can order the former employee to return and stop using company information, bar solicitation of covered clients where a valid covenant exists, and award damages for lost profits on diverted business, proven account by account. Under the Texas trade secret statute a court may also award exemplary damages and attorney's fees for willful and malicious misappropriation. What a court will not do is order clients to come back or bar fair competition by a former employee who signed nothing and took nothing.

The emergency relief available in the first days, a temporary restraining order and then a temporary injunction, is described in the guide to emergency relief in Texas business cases.

What it costs the business beyond the lost accounts

Management time is the first cost: an owner and the sales lead will spend weeks on declarations, document review and the hearing. Client relationships can be strained by subpoenas for their testimony about who called whom. And the case can expose the company's own practices, such as how loosely the customer data was protected, which the other side will use to argue it was never a trade secret. A litigator's early assessment weighs these against the revenue at stake before anything is filed.

Fixing the next departure

Most of these disputes trace back to onboarding documents that were never tailored to the role. A customer non-solicit tied to the accounts the employee handles, a confidentiality agreement that names the categories of protected data, an exit checklist that collects devices and certifies deletion, and access controls that log exports will do more for the next departure than any lawsuit does for this one.
