What Your NDA Actually Restricts

NDAs have become background noise - something you sign during a job interview or before a vendor call, right next to the form asking for your emergency contact. They feel routine, so people treat them as routine. They're not.

The two NDAs sitting in your email right now probably don't say the same thing. The difference between them could be years of what you can and can't say.

What "confidential information" actually means in your NDA

This is the clause that matters most. A narrow NDA protects only specifically identified trade secrets - labeled documents, named products, specific customer lists. A broad NDA defines confidential information as essentially everything you learn about the company during your time there, including information that's publicly available if it was disclosed to you in a confidential context.

Some NDAs go even further with a "residuals" clause - meaning you have to keep protecting information you remember even after you no longer have any documents. You learned it; you can't use it. That's a real thing, it's enforceable in some states, and it's worth noticing before you sign.

How long does it bind you?

NDA duration varies a lot. Some expire after 1-3 years. Some are perpetual - which sounds dramatic, but makes sense for actual trade secrets (a secret only stays a secret if you keep it forever). Most business negotiation NDAs are time-limited. Employment NDAs vary. Know your expiration date, because it determines when you can freely discuss what you learned. Many people don't.

What NDAs can't restrict

Even a well-drafted, broadly-scoped NDA has limits. It can't stop you from reporting illegal activity to a regulator or law enforcement. It can't prohibit you from discussing your own pay or working conditions with colleagues - that's protected by federal labor law. It can't prevent you from complying with a court order. Many NDAs include explicit whistleblower carve-outs; if yours doesn't, that's worth knowing.

Mutual vs. one-way: who it actually protects

A mutual NDA binds both parties. A one-way NDA binds only you. Employment NDAs are almost always one-way - you protect their information; they don't protect yours. That's standard. The issue is when a one-way NDA is presented as a mutual one in a context where both parties are exchanging confidential information. Read which direction the obligations actually run.

The clauses that catch people off guard

• Residuals clause - must protect information you remember, even without documents
• Non-solicitation bundled in - restricts you from hiring colleagues or contacting clients after you leave
• Work product ownership - anything you create during the relationship may be assigned to them
• Return or destroy - all confidential materials must be returned or deleted when the relationship ends
• Injunctive relief without a bond - they can get a court order against you very quickly, without having to post security first
