Section 8 of the National Labor Relations Act lists the workplace conduct that counts as an unfair labor practice. It sets out five categories of illegal employer behavior and seven categories of illegal union behavior, all enforced by the National Labor Relations Board (NLRB). The NLRA’s Section 8 unfair labor practices rules protect private-sector employees whether or not they belong to a union, and they reach something as ordinary as two coworkers comparing paychecks. If you believe a violation has occurred, you have six months from the date it happened to file a charge with the NLRB, and filing costs nothing.
What Section 8 Prohibits Employers From Doing
Section 8(a) contains five prohibitions, each keyed to the rights Section 7 gives employees: to organize, join a union, bargain collectively, act together for mutual aid, or refrain from any of that.1Office of the Law Revision Counsel. 29 USC 157 – Rights of Employees
Section 8(a)(1) forbids interfering with, restraining, or coercing employees who exercise those rights.2Office of the Law Revision Counsel. 29 USC 158 – Unfair Labor Practices This is the broadest provision and the one most often charged. Threatening to close a facility if workers unionize, promising raises to derail organizing, and watching employees at union meetings all fit here. Intent is not required. If the conduct would reasonably tend to chill workers from exercising their rights, that is enough.
Section 8(a)(2) bars an employer from dominating or financially backing a labor organization. The target is the “company union” that looks independent but answers to management.
Section 8(a)(3) prohibits using any employment decision, from hiring to firing to shift assignments, to encourage or discourage union membership. Demoting a union steward or refusing to hire someone because their last employer was unionized are textbook violations.
Section 8(a)(4) protects the enforcement process itself. An employer cannot retaliate against a worker who files a charge or testifies in a Board proceeding. Without this, no one would report anything.
Section 8(a)(5) requires the employer to bargain in good faith with the union that represents its employees. Good faith means meeting at reasonable times and genuinely negotiating over wages, hours, insurance, safety, and similar mandatory subjects.3National Labor Relations Board. Employer/Union Rights and Obligations Refusing to hand over information the union needs to negotiate counts as a refusal to bargain. Neither side has to make concessions or reach a deal, but going through the motions with no real intent to negotiate, sometimes called surface bargaining, is a violation. If the parties genuinely reach impasse, the employer may implement its last offer, and the union can challenge whether a real impasse existed by filing a charge.
What Section 8 Prohibits Unions From Doing
Section 8(b) applies the same enforcement machinery to unions that abuse their power over employees.
Section 8(b)(1) prohibits restraining or coercing employees in the exercise of their Section 7 rights, which includes the right not to participate in union activities.2Office of the Law Revision Counsel. 29 USC 158 – Unfair Labor Practices Physical threats, blocking entrances during a strike, and intimidating workers who cross a picket line can all trigger it. Unions can still write their own internal membership rules, but not use them to punish statutory rights.
Section 8(b)(2) prevents a union from pressuring an employer to discriminate against a worker based on union status. Pushing for someone’s firing because they criticized union leadership, rather than for failing to pay required dues, crosses the line.4U.S. Government Publishing Office. 29 USC 158 – Unfair Labor Practices
Section 8(b)(3) puts the duty to bargain in good faith on the union side as well. Surface bargaining and stalling by a union are just as unlawful as when an employer does them.
Section 8(b)(4) restricts certain strikes and boycotts, especially secondary boycotts, where a union pressures a neutral business to stop dealing with the employer the union actually has a dispute with. The rule keeps labor disputes from cascading through unrelated companies.
Section 8(b)(5) bars excessive or discriminatory initiation fees for workers covered by a union-security agreement. Section 8(b)(6) outlaws featherbedding, meaning demands that an employer pay for services that are not actually performed. The Board reads this narrowly: it covers pay for no work at all, not disputes over staffing levels.
On top of these specific prohibitions, a union owes a duty of fair representation to everyone in the bargaining unit, not just members. It must act fairly, in good faith, and without discrimination in bargaining, grievances, and hiring hall referrals.5National Labor Relations Board. Right to Fair Representation A union that refuses to process your grievance because you are not a member, or because you criticized officers, breaches that duty. The duty does not reach rights you can enforce on your own, like a workers’ compensation claim, or purely internal union discipline.
You Do Not Need a Union to Be Protected
Section 8 protects employees who have no union at all. Talking with a coworker about wages, circulating a petition for better hours, or jointly refusing to work in unsafe conditions is “protected concerted activity” under Section 7, and your employer cannot punish you for it.6National Labor Relations Board. Concerted Activity Even one employee can be covered when raising complaints on behalf of coworkers, trying to organize group action, or preparing for it.
The Board treats wages as a vital term of employment that employees have every right to discuss openly.7National Labor Relations Board. Your Rights Workplace rules that forbid employees from sharing salary information with each other violate Section 8(a)(1). Confidentiality policies can protect genuine trade secrets, but they cannot be used to shut down pay conversations. This protection applies regardless of immigration status.
Protection has limits. You can lose it if your conduct becomes egregiously offensive, if you make statements you know are false, or if you disparage your employer’s products without tying the criticism to a workplace concern.
Who Is Not Covered
The NLRA reaches most private-sector employees, but several groups fall outside it. You are not protected under Section 8 if you are an agricultural laborer, a domestic worker, an independent contractor, a supervisor, or an employee of a parent or spouse.8Office of the Law Revision Counsel. 29 USC 152 – Definitions Public-sector employees at any level of government are also excluded, along with workers covered by the Railway Labor Act, mainly airline and railroad employees.9National Labor Relations Board. Are You Covered? One narrow exception: a supervisor can be covered if the retaliation was for refusing to violate the NLRA. Federal employees pursue their claims through the Federal Labor Relations Authority under a different statute, and state and local government workers rely on whatever state public-employee labor law applies.
How to File a Charge
The Six-Month Deadline
The most important thing to know first: you have six months from the date of the unfair labor practice to file.10Office of the Law Revision Counsel. 29 USC 160 – Prevention of Unfair Labor Practices Miss it and the Board cannot issue a complaint no matter how strong your case is. The clock runs from the date of the violation, not the date you found out about it. The only statutory exception is for filers whose military service delayed them.
The Forms
The NLRB uses two standardized forms. Form NLRB-501 is for charges against an employer; Form NLRB-508 is for charges against a union. Both are available as fillable PDFs on the NLRB website.11National Labor Relations Board. Fillable Forms Each form asks for your name and address, the legal name and address of the party you are charging, the subsections of 8(a) or 8(b) you believe were violated, and a factual statement of what happened.12National Labor Relations Board. Charge Against Employer Include dates, locations, and people involved. A concise narrative is what the Board needs, not a legal brief. Note any witnesses, but you do not have to attach their statements.
Filing and Investigation
File with the NLRB Regional Office that covers where the violation occurred. The Board’s E-Filing system accepts charges online before midnight in the receiving office’s time zone, and you can also file by mail or in person.13National Labor Relations Board. Frequently Asked Questions – eService
Filing is free, and you do not need a lawyer. A Board agent then investigates by interviewing the parties, reviewing documents, and gathering evidence. The regional director typically decides whether the charge has merit within 7 to 14 weeks, though complex cases run longer.14National Labor Relations Board. Investigate Charges If the evidence supports the charge, the regional director issues a formal complaint and schedules a hearing before an administrative law judge, and Board staff prosecutes the case.
If the regional director dismisses the charge, you have 14 days to appeal to the General Counsel in Washington, D.C.15eCFR. 29 CFR 101.6 – Dismissal of Charges and Appeals to the General Counsel The General Counsel reviews the full file and can uphold the dismissal or send it back for further action. You may ask to present the appeal orally, but the request is granted at the General Counsel’s discretion.
What You Can Get If You Win
The NLRB does not impose fines or criminal penalties. Its remedies are meant to put the affected party back where they would have been without the violation. Common remedies include:
- Reinstatement to the same or a substantially equivalent job for a worker who was illegally fired.
- Back pay for the difference between what the employee earned and what they would have earned, from the date of the unlawful action until reinstatement or a valid offer of reinstatement.16Office of the Law Revision Counsel. 29 US Code 160 – Prevention of Unfair Labor Practices
- A cease-and-desist order requiring the party to stop the unlawful conduct.
- A workplace notice describing the violation and promising future compliance.
Back pay is taxed as wages in the year received. The employer reports it on a W-2, and income tax plus Social Security and Medicare taxes apply.17Internal Revenue Service. Reporting Back Pay and Special Wage Payments to the Social Security Administration Interest, penalties, and personal-injury damages included in a settlement are not wages. For Social Security credit, you can ask that back pay be allocated to the periods when it should originally have been paid rather than a single year.
When waiting for the full administrative process would cause irreparable harm, the Board can go to federal district court for a temporary injunction under Section 10(j), which halts the unlawful conduct while the case continues.18National Labor Relations Board. 10(j) Injunctions Section 10(l) requires the Board to seek an injunction in secondary-boycott and certain unlawful picketing cases.
If you are unsure whether your workplace is covered or whether what happened qualifies, the NLRB’s regional offices will help you figure it out before you file. Given the six-month deadline, that is a call worth making early.
