Employee NDA Laws in Colorado: What You Need to Know

Federal law does not directly regulate employee NDAs. Instead, federal trade secret protection operates through the Defend Trade Secrets Act (DTSA), 18 U.S.C. § 1836, which allows companies to sue for misappropriation of trade secrets in federal court and provides for injunctive relief and damages. Federal law also establishes that reasonable confidentiality agreements protecting genuinely confidential information are enforceable as a matter of contract law and state common law doctrine.

The Federal Trade Commission (FTC) has challenged certain overly broad confidentiality agreements as unfair or deceptive practices under the FTC Act, but this primarily affects non-competes rather than pure NDAs. Most NDA enforceability is determined by state law. Federal courts recognize that employers have a legitimate interest in protecting trade secrets, but they defer to state law on what constitutes a reasonable restriction on employee activity post-termination.

Colorado strictly limits NDA enforceability through Colorado Revised Statutes § 8-2-113, which governs restrictive covenants including confidentiality agreements. Colorado courts apply a three-prong test: (1) the restriction must protect a legitimate business interest; (2) the restriction must be reasonable in temporal, geographic, and occupational scope; and (3) the restriction must not impose an undue hardship on the employee or public policy.

Unlike many states, Colorado presumes non-competes and broad restrictive covenants are unreasonable and unenforceable unless the employer proves otherwise. This heightened scrutiny also applies to NDAs that function as non-competes by preventing employees from working in their field. Colorado's Uniform Trade Secrets Act (C.R.S. § 7-57-102) defines trade secrets narrowly: information must derive independent economic value from not being generally known and be subject to reasonable efforts to maintain secrecy.

Colorado law is significantly stronger for employees than federal baseline. State law requires employers to affirmatively prove both the legitimacy of the business interest AND the reasonableness of the restriction. Merely labeling information "confidential" is insufficient. The employer must show the information actually qualifies as a trade secret or confidential business information. Additionally, Colorado prohibits NDAs that restrict employees from using general knowledge, skills developed during employment, or information that becomes public domain.

Colorado covers all employers with no size threshold. Remedies available under state law include injunctive relief, damages for breach, and attorney's fees if the prevailing party demonstrates the NDA was unenfoceable or the breach claim was frivolous. However, employees can also sue employers for enforcing unreasonable NDAs, arguing breach of the implied covenant of good faith and fair dealing.

Colorado law contains important exceptions that favor employees. First, NDAs cannot prohibit use of general knowledge, skills, or experience acquired during employment. If an employee learned a skill through training, that skill is not protectable by an NDA, even if training occurred on company time.

Second, publicly available information is never protectable by an NDA. Once information enters the public domain, an employer cannot enforce an NDA restricting its use. Third, information independently developed by the employee using only their own resources is not subject to an NDA, even if similar to employer information.

Fourth, Colorado public policy strongly disfavors restrictions that effectively bar an employee from working in their chosen profession. An NDA that prevents a software engineer from working as a software engineer anywhere is likely unenforceable. Fifth, implied covenant of good faith and fair dealing limits enforceability; employers cannot threaten NDA enforcement for pretextual reasons or to retaliate against whistleblowers.

Sixth, common employer defenses include: (1) the information does not actually qualify as a trade secret under C.R.S. § 7-57-102; (2) the restriction exceeds reasonable temporal, geographic, or occupational scope; (3) the employer failed to take reasonable measures to maintain secrecy; (4) the employee's conduct was necessary to fulfill a legal obligation or report illegal activity; and (5) the restriction imposes undue hardship. Seventh, employees can work for competitors if they do not use actual trade secrets—merely working in the same industry is permitted.

Step 1 – Document Everything. Immediately create a written record of: (a) the exact NDA language you signed, including date signed and any amendments; (b) what specific information you used or disclosed (dates, context, who received it); (c) whether that information was actually confidential or trade secret—did it exist in public domain, was it independently known to you, or did you develop it yourself?; (d) any communications from your employer claiming you violated the NDA (emails, cease-and-desist letters, HR notices); and (e) your job responsibilities and what work you performed. Store copies in secure personal email, not on employer systems.

Step 2 – Understand the Specific Allegations. Request in writing from your employer or their counsel: (1) exactly what information they claim you disclosed or used; (2) the specific employees, competitors, or third parties allegedly harmed; (3) when the alleged violation occurred; and (4) what damages they claim. This forces them to articulate their case and often reveals weaknesses. Do not admit to any violation. Respond only with factual clarifications: "I did not disclose X; I used only publicly available Y; my work on Z was independent."

Step 3 – Consult an Employment Attorney Before Responding. Contact a Colorado employment law attorney specializing in trade secrets and restrictive covenants within 5-7 days of receiving any enforcement threat. Provide all documentation from Step 1. The attorney will assess: (a) whether the information actually qualifies as a trade secret under C.R.S. § 7-57-102; (b) whether the NDA is reasonable in scope and duration under C.R.S. § 8-2-113; (c) whether your conduct was protected (legitimate use of general skills, use of public information, or legal obligation to disclose); and (d) whether the employer is acting in bad faith or retaliating. If the NDA is likely unenforceable, your attorney will craft a response letter explaining why. Do not send any response without attorney review.

Step 4 – File a Demand Letter (If Appropriate). If your attorney believes the NDA is unenforceable or the enforcement threat is retaliatory, send a formal demand letter from your attorney to the employer's counsel. This letter should: (1) clearly state the NDA is unenforceable under Colorado law; (2) cite specific case law and statutory provisions (C.R.S. § 8-2-113 presumption against enforceability, C.R.S. § 7-57-102 trade secret definition); (3) assert that continued threats constitute tortious interference with prospective employment contracts or breach of the implied covenant of good faith and fair dealing; (4) demand the employer cease enforcement within 10 business days; and (5) reserve all remedies including attorney's fees under C.R.S. § 8-2-113(4).

Step 5 – File a Declaratory Judgment Action or Counterclaim. If the employer continues enforcement threats or sues you, file a federal or state court action seeking declaratory judgment that the NDA is unenforceable. In Colorado state court (file in District Court in the county where you worked or reside), you can: (a) seek a declaratory judgment under C.R.S. § 6-1-702 that the NDA violates C.R.S. § 8-2-113; (b) counterclaim for damages from wrongful enforcement, breach of implied covenant of good faith, tortious interference, or tortious discharge if termination followed enforcement; and (c) request attorney's fees under C.R.S. § 8-2-113(4) if you prevail. In federal court, file in the U.S. District Court for Colorado (Denver, Pueblo, or Grand Junction division depending on location), alleging state law claims under diversity jurisdiction.

Step 6 – Respond to Litigation. If the employer files suit in Colorado state or federal court, your attorney will file an Answer and raise affirmative defenses: (1) the NDA is unenforceable under C.R.S. § 8-2-113 because it is unreasonable in scope or protects non-trade secrets; (2) the information you used qualifies as general knowledge, public information, or independently developed information not subject to protection; (3) the employer failed to maintain reasonable secrecy measures; (4) your conduct was protected whistleblowing or legally required disclosure; and (5) the enforcement action constitutes breach of the implied covenant of good faith and fair dealing. Discovery will include document production (all communications about the NDA, trade secret designation, and your work), interrogatories, and depositions. Prepare to demonstrate through evidence what you actually disclosed, whether it was truly confidential, and whether you had a right to disclose it.

Step 7 – Assess Settlement. Your attorney may propose settlement negotiation once discovery reveals the employer's weak evidence or the NDA's clear unenforceability. Settlement options include: (a) mutual release of claims; (b) acknowledgment the NDA is unenforceable; (c) payment by employer for attorney's fees if they pursue retaliatory enforcement; or (d) modification of the NDA to narrower, reasonable scope. Do not settle without full attorney advice on future implications.
