Protected Concerted Activity: Speech and Group Action Without a Union

Federal law protects employees who act together about pay, hours, safety or other conditions of work, and that protection does not depend on having a union. It comes from Section 7 of the National Labor Relations Act, which gives employees the right to engage in "concerted activities for the purpose of collective bargaining or other mutual aid or protection." An employer that fires, disciplines or threatens someone for that activity commits an unfair labor practice. The catch is that the protection has boundaries most workers have never been told about.

Who actually holds the right

Section 7 rights belong to "employees" as the Act defines them, and the definition excludes several large groups. Supervisors and managers are outside it, as are independent contractors, agricultural laborers, domestic workers employed in a home, people employed by a parent or spouse, and employees of railroads and airlines, who are covered by the Railway Labor Act instead.

Public employees are also outside the NLRA. Federal workers have rights under a separate statute administered by a different agency, and state and local government workers depend on whatever their state's public-sector labor law provides — which in some states is a great deal and in others is almost nothing. This is one of the clearest federal-versus-state divides in employment law: the federal Act sets the rule for private-sector workers, while state law governs the public sector entirely.

Everyone else in the private sector is covered whether or not their workplace has ever seen a union card. The Board's own description of the rights it protects is written for non-union workplaces as much as for organized ones.

What makes activity "concerted"

The statutory text sits at 29 U.S.C. § 157, but the working definition comes from Board decisions. Activity is concerted when it is engaged in with or on the authority of other employees, not solely by and on behalf of the individual. It also includes an attempt to initiate group action — so the first employee to raise an issue can be protected even before anyone joins.

• Two employees comparing pay in a message thread and deciding to ask for a raise together.
• A written complaint about scheduling signed by several members of a shift.
• One employee raising a group grievance at a staff meeting on behalf of coworkers.
• A social media post about understaffing that draws coworker replies and discussion.
• A group of workers leaving an unheated building without first making a formal demand.

That last example is not hypothetical. In NLRB v. Washington Aluminum (1962), the Supreme Court held that employees who walked out over an unheated shop were protected even though they had presented no specific demand and no union was involved. The activity must also be for "mutual aid or protection," which means it has to relate to terms and conditions of employment rather than to a purely personal dispute.

Note: Individual griping that neither seeks nor invites group action is generally not concerted. The Board has drawn that line more and less strictly over time, and the difference often turns on whether the employee was speaking to coworkers or only to a manager.

Why pay discussion is the classic case

Discussing wages with coworkers is the most common protected concerted activity in the country and the one employees most often believe is forbidden. A rule that prohibits employees from discussing their own pay, or that treats compensation as confidential information, is a textbook Section 8(a)(1) problem. So is a manager telling an employee that raising pay with colleagues is a fireable offense.

Two overlapping layers sit on top of that federal protection. Many states have enacted their own pay-transparency and wage-discussion statutes with their own penalties, and a separate line of federal and state law regulates what an employer may ask a candidate about earlier earnings — the subject of our explainer on salary history bans and compensation questions during hiring. An employer can violate all three regimes with a single sentence in a policy manual.

Where protection stops

Section 7 also does not create a general free-speech right at work. A private employer may still discipline employees for speech that is not concerted and not about working conditions. And Section 7 is not a discrimination statute — harassment and bias claims run through Title VII and the parallel state laws described in the EEOC's guidance library, not through the labor Board.

Handbook rules and severance terms: a standard in motion

The most practically important area is the effect of Section 7 on written policies. The Board has repeatedly changed the test for when a facially neutral workplace rule unlawfully chills protected activity, and the test has flipped with changes in the Board's membership more than once in the last decade.

The current framework, adopted in the Board's 2023 Stericycle decision, treats a rule as presumptively unlawful if a reasonable employee could interpret it to restrict Section 7 activity, leaving the employer to justify it by showing a substantial business interest that no narrower rule could serve. In the same year, the Board held in McLaren Macomb that merely offering a severance agreement with sweeping confidentiality and non-disparagement terms can itself violate the Act.

Neither decision sits on stable ground. The Board lost the quorum it needs to issue decisions in early 2025 and did not regain one until two new members were sworn in in January 2026, alongside a new General Counsel. As of mid-2026 both decisions remain the Board's stated standards and neither has been overruled, but this is an area whose doctrine has historically moved with agency composition, and practitioners widely expect it to be revisited. Anyone drafting policy language should confirm the governing test at the Board's own site rather than relying on a summary written a year earlier.

The practical drafting lesson does not change with the doctrine. Rules that name the conduct they actually target, and that carve out protected activity in plain language, survive under either test. Broad prohibitions on "discussing company matters" or "negative comments" do not. That is the same drafting problem discussed in our guide to what an employee handbook creates and what it should avoid, and it recurs in appearance rules, where restrictions on union insignia have their own Board history, covered in our analysis of where employer discretion over dress and grooming ends.

Common questions

My handbook says pay is confidential. Is that lawful?

A rule barring employees from discussing their own wages with each other is very likely unlawful under Section 7, and it has been treated that way by the Board under every recent version of the test. Rules protecting genuinely confidential payroll data that an employee accesses as part of their job are different. If the policy is broad enough that a reasonable employee would read it as forbidding pay conversations, that breadth is the problem.

Does posting about my job on social media count?

It can. A post about working conditions that seeks or draws in coworker participation is often concerted, while a purely personal complaint usually is not. What tips the balance is whether the post relates to shared terms of employment and whether other employees engage with it. Posts that disparage the employer's products or services with no connection to a workplace dispute fall outside the protection.

How long do I have to do something about it?

Six months. Section 10(b) of the Act sets a six-month limitation period for filing an unfair labor practice charge, measured from the conduct complained of. There is no private lawsuit for a Section 7 violation — the route is a charge filed with a regional office of the National Labor Relations Board, which investigates and decides whether to issue a complaint. Missing the six-month window ordinarily ends the matter.

I signed a severance agreement with a non-disparagement clause. What now?

An overbroad clause may be unenforceable as to protected activity and, under current Board law, offering it may itself be unlawful. That does not automatically void the rest of the agreement or the payment already made. Because the Board's position on severance terms has moved recently and may move again, treat any general statement about enforceability as provisional and check the current standard before acting on it.

If you think a right has been violated

1. Write down what happened and when. Who was involved, what was said, and which coworkers were part of the activity. Concerted-ness is a factual question and contemporaneous notes matter.
2. Keep the underlying communications. Group messages, signed complaints and email threads are the evidence that the activity was shared rather than individual.
3. Check whether you are covered. Supervisory status, contractor classification and public-sector employment take a case outside the Act entirely.
4. Note the six-month deadline. Diary it from the date of the discipline or the statement, not from when you learned the law existed.
5. File with a regional office. Charges are filed with the Board, which investigates at no cost to the charging party. Naming the specific rule or statement helps.
6. Separate the theories. If the same conduct also involves discrimination or a safety complaint, those go to different agencies on different clocks.

Group complaints about hazards are a good example of overlapping routes. The same conversation can be protected concerted activity before the Board and a safety report governed by the documentation rules described in our guide to OSHA injury reporting and recordkeeping. Filing in one forum does not preserve the deadline in the other, so track them separately from the start.
