Can You Get in Trouble for Leaving a Bad Glassdoor Review?

Why most negative Glassdoor reviews are protected

In the United States, the National Labor Relations Board protects "concerted activity", which includes employees discussing wages, hours and working conditions, and that protection extends to many online posts. A bad Glassdoor review saying pay is below market or management ignores safety concerns often falls inside it.

Glassdoor makes the same point in its own guidance for employees: employers generally cannot punish workers for posting reviews about working conditions. The protection mainly covers non-supervisory employees, and it applies to discussion of the workplace rather than to any statement at all.

Opinion is also hard to sue over. "My manager was unfair" or "the culture is toxic" is a view, not a provable fact, and defamation law generally targets false statements of fact.

What makes a bad Glassdoor review risky

Risk rises sharply when a review moves from opinion into one of three areas. Each also breaks Glassdoor's own rules, so the same review can be removed by Glassdoor and pursued by the employer.

The table is a general guide, not legal advice. Laws differ by country and state, and anyone facing a specific threat should speak to an employment lawyer.

Can you be fired for leaving a bad review on Glassdoor?

For a protected review, firing or disciplining a non-supervisory employee in the United States can be unlawful, and the employee can file a charge with the NLRB. Remedies in successful cases can include reinstatement and back pay.

Protection is weaker or absent when the review reveals confidential information, makes false and damaging factual claims, or harasses named colleagues, and when the company has a lawful policy against that conduct. Supervisors and managers have less protection under federal labor law than other employees.

Outside the United States the position varies. In the United Kingdom, for example, defamation claims require serious harm, and a business must show serious financial loss under the Defamation Act 2013, which sets a high bar for suing a reviewer.

Can you be sued for a bad Glassdoor review?

Yes, it happens, though rarely and usually for specific reasons. Employers have sued reviewers mainly for defamation, where a review states false facts, and for breach of contract, where a severance or confidentiality agreement covers what was posted.

Defamation claims face obstacles. The employer must show the statement is a false fact rather than opinion, and when the reviewer is anonymous it must first ask a court to make Glassdoor disclose their identity, which Glassdoor typically contests. In 2017, a federal appeals court upheld a grand jury subpoena requiring Glassdoor to provide reviewer information in a criminal fraud investigation, which shows disclosure is possible, but civil cases face a higher bar.

Severance agreements have also changed. In *McLaren Macomb*, decided in February 2023, the NLRB held that offering severance agreements with broad confidentiality and non-disparagement terms that restrict employees' labor rights is unlawful. That decision limits how far a severance agreement can stop a former non-supervisory employee from posting an honest review.

What employers can lawfully do about a negative review

Employers have legitimate options that do not involve the reviewer at all. The safest and most effective is to treat the review as a moderation question: does it break Glassdoor's rules? If it names junior staff, leaks confidential information or comes from someone who never worked there, it can be flagged for removal. Our guide to Glassdoor's review guidelines sets out each ground.

For honest criticism, the answer is a calm public response and visible change, covered in our guide on how to respond to Glassdoor reviews. For a false factual claim that causes real damage, the employer's lawyer can assess a defamation claim against the author.

What employers should not do is hunt for the author, question staff about who posted, or discipline someone over a review about working conditions. Those steps create legal exposure and tend to become a bigger story than the review. Our article on whether Glassdoor reviews are anonymous explains what employers can and cannot learn about reviewers.

How to write a critical review without legal risk

Employees who want to leave honest criticism can reduce risk with a few rules:

• Describe your own experience and label opinions as opinions.
• Stick to facts you can support, and avoid claims about crimes, fines or misconduct unless they are public record.
• Leave out client names, financial figures, product plans and anything covered by a confidentiality agreement.
• Do not name colleagues below senior leadership, and never share anyone's personal details.
• Keep the language clean; abusive wording can get an otherwise valid review removed.

These rules also keep a review inside Glassdoor's guidelines, so it is less likely to be removed after a flag.

Timing matters too. A review written in the days after a dismissal or a heated meeting is more likely to include names, accusations and details the author later regrets. Waiting until the facts are clear, and writing as if a future employer will read it, produces a review that is both safer and more persuasive to the candidates it is meant to help.

Where this leaves employers

A bad Glassdoor review is usually protected speech, and treating it as a legal problem rarely helps. The reviews that carry legal risk for the author are the same ones that break Glassdoor's rules, which is why the platform route is the right first step.
