Signing an NDA as an Employee: What to Check
By FixMyContractLast updated Sep 27, 20266 min read
An employee NDA is rarely just an NDA. The document you are handed with an offer or on your first day often combines four different promises: keeping the employer's information secret, giving the employer what you invent at work, returning its property when you leave, and sometimes not hiring its staff or taking its clients. Each one reaches a different part of your working life, so each is worth reading on its own.
For the offer letter itself — pay, equity, notice — see how to review a job offer.
What an employee NDA usually bundles together
| Part | What it asks of you | What is worth a close read |
|---|---|---|
| Confidentiality | Keep the employer's information secret, during and after the job | How "confidential information" is defined, and whether the duty ends |
| Invention assignment | Hand over rights in what you create for the job | Whether it reaches work outside hours, and your list of prior inventions |
| Return of property | Give back documents, devices and files when you leave | What the agreement treats as company property, including on your own phone or laptop |
| Non-solicitation | Not approach its clients or staff for a period after you leave | Who it covers and for how long — see non-solicitation |
The title might say "Confidentiality Agreement," "Proprietary Information Agreement" or "Confidential Information and Invention Assignment Agreement." The title usually does not show which of these parts are inside; the headings usually do.
When you might be asked to sign one
- With the offer. It is part of the package you accept. This is often the easiest time for questions, because nothing has started yet.
- On the first day. It arrives with tax and benefits forms. It is still a contract, and it is reasonable to ask for time to read it.
- Partway through the job. A new or updated agreement, sometimes tied to a promotion, a bonus or equity. Reading it against the one already signed shows what changed.
- When you leave. An exit certificate saying you have returned everything, or a severance agreement that repeats or adds duties. See should I sign a severance agreement?
What you learn at work and what you bring with you
A hard line to draw in many employee NDAs is between the employer's information and your own skills. Many agreements protect specific things — customer lists, pricing, code, plans — and say nothing about the general experience you build up. Some go further, with a definition that reaches "all information learned during employment."
- The definition and the exclusions are usually read together. Information you already knew, and information that is public, is usually excluded.
- Some agreements include a sentence saying that general skills, knowledge and experience remain yours. When there is no such sentence and this matters to you, it is a common question before signing.
Your own devices and accounts
Many people work from a personal phone or laptop at least some of the time. The return-of-property clause may say what happens to files on your own devices, and whether you are asked to hand over or wipe a personal device when you leave. A clause that treats anything work-related on your phone as company property is different from one that asks you to delete company files.
Prior inventions and side projects
If the agreement assigns inventions to the employer, it usually includes a place to list things you created before the job. Anything you leave off the list can be harder to separate later. For side projects, a common question is how the agreement treats work done on your own time and equipment — the IP assignment and background IP entries explain the terms.
Reporting and talking about work
Some employer NDAs include a sentence saying nothing in the agreement stops you from reporting to a government agency or from other activity the law protects. If yours has one, it sits alongside the confidentiality section. If it has none and this matters to you, that is a question for a lawyer — this guide does not answer it.
A non-compete inside the same document
A promise not to work for competitors after you leave sometimes sits inside the same agreement rather than in the offer letter. Non-competes inside an NDA covers how to spot one, and are non-competes still enforceable in 2026? covers the current state of US law.
Questions to ask before you sign
- Can I have a copy to read before my start date?
- Does the confidentiality duty end at some point after I leave?
- Is general skill and experience excluded in writing?
- Where do I list prior inventions and side projects?
- What happens to work files on my own devices when I leave?
- Is there a non-solicit or non-compete in this document?
FAQ
Can I negotiate an employee NDA? Asking is common. Some employers use one form for everyone and rarely change it; others are more flexible. Questions about side projects and prior inventions are a common place to start, because they are about your own work.
Does the NDA still apply after I leave? Usually, yes — the confidentiality part normally continues after the job ends, and the agreement usually says for how long. The term and the survival wording are usually read together.
Is an employee NDA the same as the one I sign before an interview? Usually not. An interview NDA usually covers one conversation. An employee NDA covers everything you see at work and often includes the invention, property and hiring promises above.
The employment papers, read together
FixMyContract reads an offer, an employment contract or an NDA and shows what each part asks of you in plain English, and what people usually ask to change. We review the documents you were sent rather than draft them; where a report shows alternative wording for a clause, it is generic text to start a discussion, not a finished clause.
