My boss says if we unionize, he'll fire everyone and start over. Is that a bluff—or a legal threat?


A Threat or a Tactic?

Hearing your boss threaten to fire everyone if you unionize is alarming—but is it legal, or just fearmongering? This guide walks you through what to know, what to ask, and what steps to take. Whether it’s a bluff or a genuine violation of labor law, you have rights—and it’s time to understand them.

Know Your Rights Under Federal Law

Under the National Labor Relations Act (NLRA), employees have the right to unionize and engage in collective bargaining. Threatening to fire employees for considering a union is generally illegal. The law protects “concerted activity” whether a union exists or not.

What Exactly Did the Boss Say?

The specific wording matters. “I’ll fire everyone” is not the same as “this business won’t survive union costs.” Write down the statement exactly as you remember it—verbatim. This could be important evidence.

Intent Matters—But So Does Impact

Even if the boss claims he was joking or “venting,” if the comment chills union organizing, it may still violate the law. The key legal question is: Would a reasonable employee feel intimidated into backing down?

Document Everything Immediately

Write down the time, date, setting, witnesses, and exact words used. Encourage coworkers who heard it to do the same. Documentation can help prove a pattern or intent.

Talk to Your Coworkers

Ask others: Did they hear the threat? How did it make them feel? Collective concern strengthens your case—and shows you’re not alone.

Don’t Respond Emotionally

Even if you’re shocked or angry, try not to react on the spot. Keep calm, and don’t argue with your boss in the moment. Escalation could complicate your legal protections.

Understand What Employers Can and Cannot Say

Employers can express opinions about unions, but cannot make threats, promises, or retaliate. “Unions can cost money” is legal. “I’ll fire you” is not.

Is It a Pattern or One-Time Incident?

Has your boss made similar comments before? Are others being disciplined or intimidated for union support? A pattern of threats is a serious red flag—and increases the likelihood of legal consequences.

Don’t Assume It’s an Empty Threat

While mass firings are rare (and risky for employers), some businesses have tried illegal tactics before. A bluff is still serious if it scares workers into submission.

File a Charge With the NLRB

If you believe your rights were violated, you can file an Unfair Labor Practice (ULP) charge with the National Labor Relations Board. It’s free, and you don’t need a lawyer to get started.

Know the Risk of Retaliation—And the Protections

Yes, retaliation can happen. But if it does, the NLRB can investigate, file complaints, and seek reinstatement or back pay. The law is on your side if you act within your rights.

Consider Getting Outside Help

You don’t have to go it alone. Many unions offer legal guidance even before you officially organize. You can also speak with a labor lawyer for a consultation.

Is Your Workplace Covered by the NLRA?

Most private-sector employees are—but some exceptions exist (e.g., agricultural, domestic workers, certain government jobs). Make sure your job is covered before taking formal steps.

Stay Off Work Devices

Don’t organize or discuss unionizing on company-owned email or equipment. Keep your organizing efforts off the clock and on your own devices to avoid any gray legal areas.

Consider the Power of Going Public

Sometimes exposing anti-union behavior—especially threats—can bring public scrutiny and corporate accountability. But be strategic. It helps to have legal or union backing first.

Union-Busting Is Big Business

Some employers hire consultants to dissuade workers from organizing. If your company brings in “union education” teams, stay skeptical. Their goal is to sow doubt—not help you understand your rights.

Threats Might Be Illegal Even Without a Union Vote

You don’t have to be in a formal election phase for a threat to be illegal. Just expressing interest in forming a union is protected—and so are the conversations around it.

Think Long-Term—Not Just Reactionary

Whether or not you unionize, a boss willing to threaten mass firings is revealing their leadership style. Consider what kind of future you want at this workplace.

Final Thought: You’re Not Alone

Thousands of workers face intimidation when exploring union rights—but many succeed by staying informed and united. Know the law, know your worth, and know that help is out there if you ask.
