Signing an Employee NDA: What You Are Actually Agreeing To, What the Law Limits, and What to Push Back On

Most people sign an NDA on their first day of a new job without reading it carefully, if they read it at all. HR presents it as standard paperwork, the day is busy, and the agreement looks like every other form you sign during onboarding. This is a mistake. Non-disclosure agreements can meaningfully limit what you can do for years after you leave the company, who you can work for, and what you can say about your experience. Understanding what you are signing before you sign it gives you the ability to ask questions, negotiate changes, or at minimum know what you have agreed to.

What an NDA Actually Covers

An NDA, or non-disclosure agreement, prohibits you from disclosing certain information to people outside the company. The key question is how the agreement defines the information you cannot share. Narrow agreements cover specifically identified trade secrets, particular technical processes, or specific product development plans. Broad agreements attempt to cover anything you learn during employment that the company considers proprietary.

Confidential information clauses that cover everything the employee observes or learns during employment are so broad they are often partially unenforceable, but that does not mean they have no effect. Even an overbroad NDA creates uncertainty about what you can and cannot say, which is often exactly what the employer wants. Employees who are unsure whether something is covered tend to say nothing about anything.

Most NDAs also cover information you receive from company clients, vendors, or partners that the company has agreed to keep confidential. This matters because you may be bound by confidentiality obligations to the company's business relationships that you had no direct role in creating.

The Duration of the Obligation

Employment NDAs typically run indefinitely for actual trade secrets, which is permissible because trade secret law already protects that information and the NDA simply reinforces it. For general confidential information, courts look more skeptically at perpetual obligations. Many NDAs limit the general confidentiality period to two to five years after employment ends, which courts are more likely to enforce.

An NDA that purports to bind you forever from discussing anything you learned at the company is likely to face enforceability challenges. Courts balance the employer's legitimate interest in protecting genuinely proprietary information against the employee's right to work in their field using the knowledge and skills they developed. Information that becomes public knowledge stops being confidential regardless of what the NDA says.

What an NDA Cannot Prohibit

Federal law carves out several categories of conduct that an NDA cannot restrict regardless of what the document says. The National Labor Relations Act protects employees' rights to discuss wages, working conditions, and other terms of employment with coworkers. A private sector employee NDA that attempts to prohibit discussing your salary with colleagues is not enforceable to that extent.

NDAs cannot prohibit reporting illegal conduct to government agencies. Employees have federal whistleblower protections that allow them to report violations of securities laws, environmental laws, workplace safety laws, and other regulations to the relevant agencies without violating an NDA. The Securities and Exchange Commission has brought enforcement actions against companies whose NDAs included language attempting to chill reporting to the SEC.

NDAs also cannot prohibit disclosing information in response to a valid subpoena or court order. If you are compelled to testify in a legal proceeding, you cannot be held liable for disclosing information in that context, though most NDAs appropriately require you to notify the company first so they can seek a protective order if they choose.

The Defend Trade Secrets Act Immunity

Federal law requires that employee NDAs entered into after May 2016 include a specific immunity notice or reference the employer's policy containing the notice. The notice informs employees that they cannot be held criminally or civilly liable under any federal or state trade secret law for disclosing a trade secret in confidence to a government official or to an attorney in connection with reporting a suspected legal violation, or in a court filing under seal.

If your NDA does not contain this notice, the employer loses the ability to seek exemplary damages and attorney fees in any trade secret lawsuit against you, though the underlying trade secret protection still applies. An absent or inadequate immunity notice does not invalidate the rest of the NDA, but it does affect what remedies the employer can pursue.

Non-Solicitation Clauses Hidden in NDAs

Many documents labeled as NDAs also include non-solicitation provisions that are functionally separate restrictions. A non-solicitation clause prevents you from recruiting your former employer's employees to leave the company or from soliciting the employer's clients. These are not confidentiality provisions, they are restrictive covenants, and they have their own enforceability rules.

Non-solicitation of employees clauses are generally more enforceable than non-competes but less absolute than people assume. A clause preventing you from directly recruiting former colleagues is typically enforceable for a reasonable period. A clause preventing any former employee from ever working at a company where a former colleague also works is overbroad and less likely to hold up.

Non-solicitation of clients clauses are evaluated based on the employee's relationship with those clients, the nature of the business, and the scope of the restriction. Courts are more willing to enforce a targeted restriction on soliciting clients you personally managed than a blanket prohibition on contacting anyone who has ever been the company's customer.

The Difference Between NDAs and Non-Compete Agreements

Non-compete clauses are sometimes included in the same document as an NDA but they are fundamentally different restrictions. A non-compete prevents you from working for competitors or starting a competing business for a period of time. NDAs only restrict what you can say, not where you can work.

Non-competes face much more legal scrutiny than NDAs. California bans them entirely for most purposes. Minnesota and North Dakota also prohibit most non-competes. The Federal Trade Commission attempted to ban non-competes nationally through a 2024 rule, though court challenges have complicated implementation. Several other states have enacted their own limits on non-compete duration and scope in recent years.

If your employment agreement bundles NDA and non-compete provisions together, the non-compete may not be enforceable in your state even if the NDA portion is fully valid. These provisions are generally severable, meaning a court can strike the non-compete while leaving the confidentiality obligations intact.

What to Push Back On Before Signing

If you have leverage when signing, typically at offer negotiation rather than day one onboarding, there are specific points worth raising. Ask for a clear definition of confidential information. Vague, catch-all definitions are the most burdensome and the most often challenged in court. A specific definition of what is and is not covered is better for both sides.

Ask about the duration for general confidential information versus true trade secrets. Agreeing to a reasonable time limit, two to five years, for general confidentiality while allowing indefinite protection for actual trade secrets is a common compromise that most employers will accept.

If there is a non-compete buried in the NDA, understand what it restricts before signing. Geographic scope, duration, and the definition of what constitutes a competitor are all negotiable. A non-compete that prevents you from working in your entire industry nationwide for two years is far more burdensome than one that prevents you from joining the employer's three direct competitors for six months.
