An unfair labor practice case begins with a charge, usually filed online, and can end in a federal court of appeals roughly a year or more later. The National Labor Relations Board received about 20,000 charges in fiscal 2023, according to the agency's own case statistics, and each one follows the same statutory pipeline. The process is adjudicative, not advisory: an allegation is a starting position, never a finding.
This article explains the system itself — the stages, the deadlines, and what each decision-maker can actually do. It publishes information, not professional advice; anyone with a live case needs counsel of their own.
What counts as an unfair labor practice?
Section 8 of the National Labor Relations Act lists the conduct that is unlawful: interfering with protected activity, dominating or discriminating because of union activity, refusing to bargain, and the comparable obligations on unions. Section 7 of the Act, passed in 1935, is the protected right itself — workers acting together for mutual aid, with or without a union. The Board's own guide to the law, published on its website and last revised in recent years, organizes the prohibited conduct around these sections.
Who can file a charge, and by when?
Any person can file: a worker, an employer, or a union. The charge must be filed within six months of the conduct alleged, a deadline the Act sets directly. Charges are filed with one of the Board's regional offices, and no fee is charged. Filing is free; proving is not.
What happens during the investigation?
A Board agent interviews witnesses and collects documents from both sides. The region's stated goal, under the case-handling procedures the Board adopted over several decades and consolidated in recent instructions, is to complete most investigations within 7 to 12 weeks. Two outcomes are possible. The regional director issues a complaint if the region finds merit, or the charge is dismissed.
A dismissal is not the end of the road. The charging party can appeal the dismissal to the Board's General Counsel in Washington. The General Counsel, a separate statutory office, controls which cases the Board ultimately hears.
What is the difference between a complaint and a decision?
A complaint is an accusation processed by an administrative agency — like an indictment, it is a charging document, not a ruling. If the region issues one, the respondent can settle, or the case goes to hearing before an administrative law judge. Those hearings resemble trials: witnesses testify under oath, exhibits are entered, and a transcript is made.
The administrative law judge issues a recommended decision. Any party can except to it, which sends the record to the five-member Board in Washington. The Board's decision is the agency's final word in nearly every case.
What can the NLRB actually order?
The Board's remedies are remedial, not punitive. The classic package — reinstatement with back pay — dates to the Board's early decisions and was sustained by the Supreme Court in NLRB v. Erie Resistor Corp., 373 U.S. 221 (1963), where the Court held remedies may undo the harm caused by unlawful conduct. The Board cannot award compensatory damages, punitive damages, or penalties in the ordinary case. Congress added a narrow penalty regime for certain employers in 2025 legislation modifying the Act; that authority is new and its application is being worked out in cases.
What if a party ignores the Board's order?
The Board has no marshals. To enforce, the Board's General Counsel petitions a United States court of appeals, and the Act's Section 10(e) governs that petition. The court reviews the record, and the standard is deferential to the agency's factual findings — but the court, not the Board, holds the contempt power. Refusals to comply end up in enforcement proceedings in the circuit where the violation occurred or where the person resides or does business.
Can a Board decision be appealed further?
Yes. A party aggrieved by a Board decision can petition the court of appeals to review it, and the Board can cross-petition to enforce. The court of appeals is where most NLRB litigation actually concludes. Further review is by certiorari to the Supreme Court, which is rare and discretionary.
How long does the whole process take?
Investigation in weeks, a hearing months later, a recommended decision after that, a Board decision perhaps a year or two from the charge, and enforcement litigation on top of that. The Board's own performance data tracks these intervals and shows wide variation by region and case type. Back pay accrues during the delay, which is one reason the General Counsel pursues compliance litigation for years after the decision.
What should a worker or employer take from the pipeline?
Two things. First, the six-month filing clock and the region's early investigation decide most cases; the expensive stages come only after a complaint. Second, every stage is contestable — dismissal appealable to the General Counsel, a recommended decision exceptable to the Board, a Board order reviewable in a circuit court. The system is designed for sequential review, and each stage narrows the questions left for the next.
How does compliance work after a decision?
A Board order is the start of the last phase, not the finish. The respondent must post the required notice, and the region monitors compliance; if back pay is owed, the case stays open until it is paid. The Board's compliance procedures — including its compliance-specification rulemaking, described on the agency's website — let the General Counsel seek court enforcement against a respondent who stalls. Back pay is computed under the Board's long-standing formula: what the worker would have earned, minus interim earnings, with interest. A compliance phase can outlast the original litigation by years.
Where does settlement fit?
Most charges settle. Regions offer informal adjustments and formal settlement agreements, and the Board's General Counsel has long policy guidance favoring settlement where remedies are secured. A settlement can restore employment and back pay without any ruling on the law at all. Parties weighing one should remember what a Board decision would otherwise produce: a public, precedential ruling that binds that respondent in future cases.
