How to Handle a Disgruntled Employee Posting Negative Comments Online

You built your business over years of hard work, and now a former employee is trying to tear it down with a keyboard. A disgruntled employee posting negative reviews about your company on Google, Glassdoor, LinkedIn, or social media can feel like a gut punch—especially when what they’re saying isn’t true.

If you’re dealing with this situation, you’re not alone. It’s one of the most common issues we handle at Cramer Law Group, and the good news is that you have more options than you might think. This guide walks you through exactly what to do, step by step, from the moment you discover the posts to the point where you may need legal intervention.

Why Former Employees Post Negative Content Online

Before deciding how to respond, it helps to understand what’s driving the behavior. Former employees who take to social media after a termination or resignation typically fall into a few categories. Some are genuinely angry and feel they were treated unfairly. Others are trying to leverage public pressure—hoping that negative posts will push you toward a settlement or severance payment. A smaller number are deliberately trying to sabotage your business because they feel wronged.

The motivation matters because it shapes your strategy. An employee who is venting out of frustration may stop on their own after a few days. One who is running a coordinated campaign to damage your reputation—posting across multiple platforms, contacting your clients, or encouraging others to leave negative reviews—requires a more aggressive response.

Regardless of the motivation, the posts can cause real damage. Negative online content can drive away prospective clients, make it harder to recruit employees, and create anxiety for your current team. The key is responding strategically rather than emotionally.

Step 1: Document Everything Before You Do Anything Else

The single most important thing you can do right now is preserve evidence. Screenshots are your best friend. Before you report a post, respond to it, or contact the former employee, capture everything.

For each post, save a screenshot that shows the full content of the post, the name or username of the person who posted it, the date and time it was posted, the platform where it appeared, and any comments or engagement on the post. Store these in a dedicated folder—digital or physical—along with the date you captured them. If the former employee is also sending emails, texts, or voicemails, preserve those as well. Do not delete anything.

This documentation serves two critical purposes. First, it gives you evidence if you need to take legal action later. Second, it establishes a timeline that demonstrates a pattern of behavior, which is important if you’re seeking an injunction or filing a defamation claim.

Step 2: Determine Whether the Posts Are Defamatory or Protected Speech

Not every negative post is actionable. Under both federal and Illinois law, people have a right to express opinions. The legal line is between opinion and false statements of fact.

Defamation occurs when someone makes a false statement of fact about you or your business, publishes it to a third party, and the statement causes actual harm. For example, a former employee who posts “This company doesn’t pay overtime” when you have full payroll records showing otherwise is making a false statement of fact that could constitute defamation.

Protected speech includes opinions, no matter how harsh. A post that says “Worst company I’ve ever worked for” is an opinion and is generally protected. Similarly, if a former employee discusses their own experience—“I felt undervalued and overworked”—that’s typically not actionable because it’s a subjective statement about their feelings.

There is also an important exception under the National Labor Relations Act. If a current or former employee is posting about wages, working conditions, or workplace safety—even in an unflattering way—that speech may be considered protected concerted activity under federal labor law. Attempting to silence this type of speech can expose your business to unfair labor practice charges, which is a far worse outcome than a bad Glassdoor review.

This is exactly why it’s important to consult with an employment attorney before you take action. What feels clearly defamatory to you may actually be protected, and responding the wrong way can create more legal exposure than the original post.

Step 3: Report the Content to the Platform

If the posts violate the platform’s terms of service, reporting them is your most efficient first step. Every major platform—Google, Glassdoor, LinkedIn, Facebook, Instagram, X (formerly Twitter), and Yelp—has community guidelines that prohibit harassment, threats, hate speech, and certain types of false or misleading content.

When you file a report, be specific. Don’t just flag the post as “inappropriate.” Identify the exact guideline the post violates and explain why. If the post contains a false factual claim, state what the false claim is and note that you have evidence to the contrary. If the post includes threats or personal information about your employees, highlight that specifically.

Platform response times vary. Google business review removals can take several days to several weeks. LinkedIn tends to act more quickly on reports of harassment. Glassdoor reviews are notoriously difficult to remove unless they clearly violate the platform’s specific content guidelines.

A practical tip: if you own the Google Business Profile or employer page on Glassdoor, you can respond publicly to the review. Keep your response professional, brief, and factual. Do not get into a back-and-forth argument. A well-crafted owner response that says “We take all feedback seriously and encourage anyone with concerns to contact us directly” can actually signal professionalism to prospective clients and candidates reading the reviews.

Step 4: Send a Cease-and-Desist Letter

If the posts are clearly defamatory and the former employee shows no signs of stopping, a cease-and-desist letter from your attorney is the next step. This is a formal letter that identifies the specific false statements, demands that the person stop making them and remove existing posts, and notifies them that continued defamation will result in legal action.

A well-drafted cease-and-desist letter accomplishes several things. It puts the former employee on notice that their conduct has legal consequences, which often causes the behavior to stop. It also establishes your intent to pursue legal remedies, which becomes important evidence if you do file a lawsuit later. And for employees who are posting because they want attention or leverage, the formality of a legal letter often resets the dynamic.

At Cramer Law Group, we draft cease-and-desist letters regularly for employers dealing with this exact issue. In many cases, the letter alone resolves the situation without the need for litigation. If you need help with this step, contact our team to discuss your options.

Step 5: File a Police Report If the Behavior Escalates

Online defamation sometimes crosses the line into criminal harassment. If the former employee is contacting you repeatedly after being asked to stop, showing up at your office, making threats, contacting your clients or customers to make false statements, or encouraging others to harass you or your employees, you should file a police report.

In Illinois, harassment and cyberstalking are criminal offenses. Under 720 ILCS 5/26.5-3, a person commits cyberstalking when they use electronic communications to threaten or harass another person on at least two separate occasions. Filing a police report creates an official record of the conduct and opens the door to criminal penalties that go beyond what a civil lawsuit can accomplish.

A police report also strengthens any future request for a restraining order or injunction. Courts want to see that you’ve taken reasonable steps to stop the behavior before asking for court intervention, and a police report demonstrates exactly that. If the former employee is also targeting your current employees, encourage them to file their own reports and to document any workplace harassment they experience as a result.

Step 6: Consider Seeking a Court Injunction

In extreme cases—where the former employee is engaged in a sustained campaign of defamation, harassment, or interference with your business—you may need to seek an injunction from the court. An injunction is a court order that legally prohibits the person from continuing the harmful conduct. Violating an injunction can result in contempt of court charges, fines, and even jail time.

The legal standard for obtaining an injunction is high. In Illinois, you generally need to demonstrate that you are likely to succeed on the merits of your underlying claim (such as defamation or tortious interference), that you will suffer irreparable harm without the injunction, that the balance of hardships tips in your favor, and that the injunction serves the public interest.

Courts are particularly cautious with injunctions that restrict speech because of First Amendment considerations. However, when the speech at issue consists of provably false statements of fact that are causing measurable harm to your business, courts are more willing to act. This is especially true when the person has been given opportunities to stop and has continued anyway.

An injunction is not a first step—it’s a last resort after you’ve documented the conduct, reported it to platforms, sent a cease-and-desist letter, and filed a police report. But when it’s necessary, it’s a powerful tool.

Proactive Steps to Protect Your Business Before Problems Start

The best time to deal with a disgruntled employee posting online is before it happens. There are several proactive measures every Illinois employer should have in place.

Non-disparagement clauses in severance agreements. When you offer a departing employee a severance package, including a mutual non-disparagement clause gives both parties a contractual obligation not to make negative public statements. If the employee signs the agreement and then posts defamatory content, you have a breach of contract claim on top of any defamation claim. Our team regularly includes these provisions when drafting severance agreements for employers.

Confidentiality and social media policies. Having clear policies in your employee handbook about social media conduct, confidentiality, and company reputation sets expectations from day one. While these policies don’t override an employee’s rights under the NLRA, they do establish a framework for what’s acceptable and give you documentation to point to if a violation occurs. Our HR compliance services can help you develop these policies.

Non-compete and non-solicitation agreements. If the former employee is not just posting negative content but is also soliciting your clients or recruiting your staff, a well-drafted non-compete or non-solicitation agreement gives you additional legal tools to stop the behavior. Under the Illinois Freedom to Work Act, these agreements must meet specific requirements to be enforceable, so it’s critical that they’re drafted correctly.

A strong online reputation. Businesses that have a steady stream of positive reviews and active online presence are far less vulnerable to a single disgruntled employee’s posts. Encourage satisfied clients and current employees to leave reviews. A business with 50 positive Google reviews and one negative one is in a much stronger position than a business with two reviews total and one of them is negative.

What Not to Do When an Employee Posts About You Online

When you discover negative posts, the urge to respond immediately is strong. Resist it. There are several common mistakes that can make the situation significantly worse.

Do not respond emotionally or engage in a public argument. Every word you post can be used against you in a future legal proceeding, and a heated exchange makes your business look unprofessional to anyone watching.

Do not disclose confidential employment information. Even if the employee is lying about why they were terminated, you cannot publicly share the real reasons. Doing so could expose you to claims under state and federal privacy laws, and if the employee’s termination involved a medical condition or disability, you could face liability under the ADA or Illinois Human Rights Act.

Do not retaliate by posting negative information about the former employee, contacting their new employer, or interfering with their job search. These actions can result in tortious interference claims and may even constitute harassment.

Do not ignore the situation entirely. While some posts are best left alone, a sustained pattern of false and damaging content will not resolve itself. Failing to act can signal to the former employee that there are no consequences, emboldening them to escalate.

When to Call an Employment Attorney

You should consult with an attorney as soon as you realize the situation is not going to resolve on its own. Specifically, get legal advice if the posts contain false statements of fact that are harming your business, the former employee is contacting your clients or customers, the behavior has escalated to threats or in-person harassment, you’re considering sending a cease-and-desist letter, or you want to review your severance agreements and employment contracts to prevent future issues.

At Cramer Law Group, we represent Illinois employers dealing with exactly these situations. We’ll evaluate the posts, advise you on what’s actionable versus what’s protected speech, and build a strategy that protects your business without creating additional legal risk. We handle everything from cease-and-desist letters to full employment litigation when necessary.
