A non-disclosure agreement, or NDA, is a legal contract in which an employee promises not to share an employer’s confidential information, trade secrets, or proprietary business details. It depends: breaching an NDA after quitting isn’t automatically a crime, but it is a civil legal violation in Pennsylvania, and in some cases it can trigger criminal liability too, depending on what information was disclosed and how.
Understanding the difference between civil and criminal exposure matters for anyone who signed an NDA and is wondering what happens if they violate it after leaving a job.
NDAs Remain Enforceable After You Quit
Signing an NDA doesn’t end when employment does. These agreements generally remain enforceable after separation, whether the employee resigned, was laid off, or was terminated. Pennsylvania courts will enforce an NDA provided it is reasonable in scope and duration and protects a legitimate business interest, such as trade secrets, client lists, or proprietary processes.
For an NDA to be enforceable, it generally must be tied to an employment relationship, supported by adequate consideration, reasonably necessary to protect a legitimate business interest, and limited in duration and geographic scope. Pennsylvania courts have held that continued employment itself can serve as sufficient consideration for an NDA signed after hiring, meaning employees don’t necessarily need extra pay for the agreement to hold up.
Breach of an NDA Is Typically a Civil Matter
Most NDA violations are treated as breach of contract, a civil issue rather than a criminal one. If a former employee discloses confidential information in violation of the agreement, the employer’s primary remedy is to sue in civil court, not to have the person criminally prosecuted.
Courts may order several types of relief: monetary damages, compensating the employer for financial losses or reputational harm caused by the disclosure, or injunctive relief, a court order requiring the former employee to stop using or sharing the information immediately. Courts sometimes award both together, particularly where a leaked trade secret causes harm that’s difficult to reverse once it’s public.
When It Might Cross Into Criminal Territory
While a standard NDA breach is civil, certain conduct connected to the disclosure can trigger criminal exposure under separate laws. If the disclosed information qualifies as a legally protected trade secret and the former employee stole, copied, or transmitted it improperly, this can implicate state or federal trade secret theft statutes, which carry criminal penalties independent of the NDA itself. Similarly, hacking into company systems, unauthorized access to computer files, or theft of physical documents can violate computer crime or theft laws regardless of what the NDA says.
In other words, it’s not the NDA breach itself that becomes criminal — it’s the underlying conduct used to access or share the information.
What Employers Must Prove
To succeed in an NDA breach lawsuit, the employer generally must show a valid, enforceable agreement existed, that the former employee disclosed or used protected information covered by it, and that the disclosure caused measurable harm, such as financial losses or reputational damage. Pennsylvania courts typically require a clear connection between the breach and the harm before awarding damages.
Limits on NDA Enforcement
Pennsylvania law doesn’t let employers use NDAs however they wish. Provisions can be challenged if they’re overly broad, unreasonably long, or attempt to suppress legally protected disclosures, such as whistleblower reports of illegal conduct or harassment. Courts examine whether the restriction is genuinely necessary to protect a legitimate business interest, rather than an attempt to silence a former employee.
Practical Guidance for Former Employees
Review the NDA’s exact language before assuming you’re free to share information once employment ends. Understand what’s actually defined as confidential, since not everything you know from a job qualifies. Avoid downloading or forwarding company files, emails, or client data after resigning. Consult an employment attorney before discussing prior work details publicly, especially with a new employer in the same industry.
Bottom Line
Breaching a non-disclosure agreement after quitting a job in Pennsylvania is not automatically a criminal offense, but it is an enforceable civil matter that can expose a former employee to damages and court orders. In situations involving trade secret theft or unauthorized computer access, criminal liability can also come into play. Anyone uncertain about their obligations under a signed NDA should consult a Pennsylvania employment attorney before sharing information from a former job.
