Are non-disparagement clauses enforceable for Glassdoor reviews?

In most cases, non-disparagement clauses that broadly prohibit employees from posting honest reviews about working conditions are unenforceable. Under Section 7 of the National Labor Relations Act (NLRA), employees have a protected right to discuss their terms and conditions of employment, which includes public criticism of their employer.

Key takeaway: While you have broad protections, these rights do not cover defamatory statements. If your review contains knowingly false information, you may still face legal liability regardless of the NDA's enforceability.

The Legal Landscape: Why Broad NDAs Are Failing

The enforceability of non-disparagement clauses has shifted significantly due to rulings from the National Labor Relations Board (NLRB). In the 2023 McLaren Macomb decision, the NLRB ruled that severance agreements containing broad non-disparagement and confidentiality clauses are unlawful because they interfere with an employee's Section 7 rights.

Key Factors Influencing Enforceability

  • Scope of the Clause: Does the language prohibit all negative speech, or is it limited to trade secrets and proprietary information?
  • Protected Concerted Activity: Does the review relate to wages, hours, or working conditions? If yes, it is generally protected.
  • Truthfulness: Defamation law still applies. If you lie about specific facts, the NDA is irrelevant; you are liable for libel.
  • Jurisdiction: States like California (via the Silenced No More Act) have strictly limited the ability of employers to use NDAs to hide unlawful acts in the workplace.

How to Evaluate Your Risk Before Posting

Before you hit submit on a Glassdoor review, perform a self-audit of your contract and your content. Follow this checklist to minimize your exposure:

  1. Review the NDA Language: Look for phrases like "prohibits any negative comment" or "disparagement of any kind." These are often viewed as overbroad.
  2. Stick to Facts: Avoid hyperbole. Instead of saying "The CEO is a criminal," say "The company failed to pay overtime for three consecutive months."
  3. Focus on Working Conditions: Ensure your review centers on the employee experience, which is the core of Section 7 protection.
  4. Check for Severability: Does your contract have a severability clause? If the non-disparagement clause is found illegal, it should not invalidate the entire employment agreement.

Key takeaway: If your review is strictly factual and relates to your employment experience, it is highly likely to be protected activity. Avoid personal attacks that do not relate to the workplace environment.

State-Specific Protections

While federal law provides a baseline, state laws offer additional layers of protection. For instance, California’s Silenced No More Act (SB 331) prohibits employers from requiring employees to sign agreements that prevent them from disclosing unlawful acts in the workplace. If your review concerns harassment, discrimination, or wage theft, these state laws often override any private NDA.

Actionable Steps for Employees

  • Document Everything: Keep records of the events you are describing in your review.
  • Consult Local Counsel: If you are concerned about a specific clause, a 30-minute consultation with an employment lawyer is a high-ROI investment.
  • Use Anonymity: While not a legal defense, using Glassdoor’s anonymous posting feature reduces the likelihood of a company identifying you and initiating a frivolous lawsuit.
