How to Respond to Union Unfair Labor Practice Charges

Your inbox just delivered a formal notice from the National Labor Relations Board (NLRB) or your state's public-sector labor relations agency. A union has filed an unfair labor practice (ULP) charge against your organization — or one of your supervisors has allegedly violated labor law. Your heart sinks. Your inbox fills with questions. Your HR director looks panicked.

This is one of the most critical moments in your labor relations cycle, yet most public-sector employers have no repeatable playbook for it.

An unfair labor practice charge is not a lawsuit. It's not an immediate catastrophe. But it is a formal allegation that your organization violated the legal rights of employees, union members, or the union itself. How you respond in the next 20 days — with evidence, tone, documentation, and precision — will determine whether the charge gets dismissed, settled quietly, escalates to a costly hearing, or becomes a precedent that shapes your future negotiations.

By the end of this article, you'll understand exactly how ULP charges work, what the NLRB and state agencies actually investigate, what documents you need immediately, how to build a defensible written answer, and how to avoid the most costly mistakes that HR directors make in panic mode.

What Is an Unfair Labor Practice Charge?

An unfair labor practice is conduct by a union or an employer that violates the rights protected by the National Labor Relations Act (NLRA) or your state's public-sector labor relations statute. The NLRB and state agencies receive approximately 20,000 to 30,000 charges per year nationally — a staggering volume that underscores how central ULP litigation is to the labor relations landscape.

Who Can File a ULP Charge?

Anyone can file a ULP charge, but unions and employers are the most frequent filers. If you're a union, you file against an employer who refuses to bargain in good faith or disciplines union activists. If you're management, you file against a union for illegal work stoppages, secondary boycotts, or failing to represent all members fairly.

Critical point: A ULP charge is filed by an individual or union officer, but the actual complainant is the labor board's General Counsel. Once you're served with a charge, you're in a government investigation — not a private dispute.

What the NLRB Actually Investigates

The NLRB's process has several distinct phases:

1. Charge filing and investigation — The charged party (you) has 20 calendar days from service of the complaint to file a written answer. Before that, the Regional Office investigates.

2. Investigation period — An NLRB agent interviews parties, collects documents, and determines whether probable cause exists that a violation occurred. This typically takes 30-90 days but can stretch longer.

3. Complaint issuance — If probable cause is found, the General Counsel issues a formal complaint and notice of hearing. You now have 20 calendar days to submit a written answer.

4. Hearing before an Administrative Law Judge (ALJ) — If the charge is not settled or dismissed, a hearing is scheduled. These typically occur 60-120 days after the complaint.

5. ALJ decision — The judge issues a written decision, which either dismisses the charge or finds a violation and orders remedies (back pay, reinstatement, posting of notice, etc.).

6. Appeal to the NLRB Board — Either party can appeal to the five-member NLRB Board in Washington. This is the final administrative step before federal court.

Timeline: From charge filing to final agency decision can range from 6 months (if dismissed early) to 18-24 months (if it goes to hearing and appeal).

Types of ULP Charges You're Most Likely to Face

As a public-sector employer, the ULP allegations that land on your desk typically fall into these categories:

Refusal to Bargain in Good Faith

This is the single most common ULP charge. It alleges that you implemented a compensation change, work rule, or employment practice without negotiating with the union first — or that you negotiated but made proposals so unreasonable or inflexible that you were clearly not bargaining "in good faith."

Common triggers:

• Announcing a salary schedule increase without union input
• Changing health insurance carriers mid-contract without notification
• Implementing a new evaluation system affecting compensation
• Unilaterally raising class sizes, adjusting shift assignments, or changing leave policies
• Refusing to discuss a union proposal or dismissing it without substantive response

The burden falls on the union to prove bad faith, but "bad faith" is broadly interpreted. Simply saying "no" to a proposal is not bad faith. But making no counter-offer, refusing to explain your position, or repeatedly changing your position without justification can be.

Unlawful Discipline or Retaliation

A union files a charge alleging that you disciplined, demoted, or terminated an employee because they engaged in union activities — organizing, filing grievances, attending union meetings, or speaking up about workplace conditions.

What the NLRB needs to prove:

1. The employee engaged in protected concerted activity (union work)
2. Management knew about it
3. The employee suffered an adverse action
4. Union activity was a motivating factor in the decision

If you can show the employee was disciplined for a legitimate, non-retaliatory reason (poor performance, attendance, safety violation), you may defend the charge. But be prepared with evidence. A contemporaneous performance file is your best defense.

Failure to Provide Information

The union requests data — salary information, benefits cost figures, headcount, work schedules, staffing ratios — that is relevant to negotiations, and you refuse or delay producing it. This is an unlawful refusal to bargain.

What unions typically request: Compensation studies, per-employee benefits costs, turnover data, job descriptions, seniority lists, leave usage statistics, and demographic breakdowns.

Your defense: Information truly not in your possession or require a reasonable delay (10-15 days) to compile. Do not refuse on confidentiality grounds alone — the NLRB will order disclosure in most cases anyway.

Violation of a Contract

If an existing CBA is in effect, either party can file a charge alleging breach. Common allegations: failing to pay earned step increases, not scheduling bargaining-unit work, assigning work to supervisors, or violating a grievance or arbitration clause.

The Immediate Response: What to Do in the First 24 Hours

1. Stop the Panic, Start the Documentation

The moment you receive notice of a ULP charge, you are in a legal investigation. Every email, text, meeting memo, and decision log from this moment forward will be examined. But equally important: preserve all existing documentation from the events the charge describes.

Do not destroy, edit, or "clean up" any documents. The charge typically describes events from a specific date range. Identify all emails, text messages, meeting minutes, personnel files, compensation records, and communications from that period and segregate them in a secure location.

2. Notify Your Labor Relations Counsel Immediately

Do not respond to the charge yourself. This is not the time for your HR director, superintendent, or finance team to draft your answer. You need legal counsel with NLRB experience immediately.

Why? Because your answer to the complaint is a legal document, filed under oath. Every assertion you make is discoverable and can be used against you at a hearing. A poorly drafted answer can destroy defenses you might otherwise have had.

What to tell your attorney in the first phone call:

• Date and method of charge service (registered mail, email, in-person)
• Who filed the charge (union, individual employee, organizer)
• Summary of the allegations
• Any ongoing negotiations with the union
• Any recent discipline, compensation changes, or management decisions affecting the unit

3. Identify Your Key Witnesses and Documents

While your attorney prepares your answer, HR should compile:

Documents (prioritized by relevance):

• All communications with the union in the relevant period (emails, meeting notes, proposals, counter-proposals)
• The current collective bargaining agreement (or expired CBA if no new agreement is in place)
• Compensation records (salary schedules, step advancement documentation, bonus/stipend records)
• Personnel files for any employees mentioned in the charge
• Board/council meeting minutes discussing the issue
• Finance records (budget documents, cost analyses, benefits cost data)
• Any studies, surveys, or compensation analyses you relied on

Witnesses (who can testify):

• The superintendent or city manager who made the decision
• The HR director or labor relations officer
• The union negotiator (your side)
• Finance or business office staff who compiled cost data
• Any supervisor involved in the disputed action

Document the chain of custody. When your attorney requests these files, you'll need to show when they were created, who has had access, and that they have not been altered.

Preparing Your Written Answer to the Complaint

You have 20 calendar days from the date of service to file your written answer. This is a hard deadline. Missing it can result in a default judgment against you — the NLRB may find the allegations true by default simply because you did not respond.

Structure of a Defensible Answer

Your written answer should:

1. Deny or admit each allegation specifically — Do not blanket-deny or blanket-admit. Address each factual assertion. "Denied," "Admitted," or "Denied in part, admitted in part" with explanation. For example:

   "Alleged that Respondent unilaterally increased health insurance employee contributions on July 1, 2024. Denied in part, admitted in part. Respondent did propose and implement an increase in employee health insurance contributions effective July 1, 2024. However, this action was taken only after Respondent presented the proposal to the Union at the bargaining table on June 5, 2024, and sought the Union's input. The Union rejected the proposal without counter-offering. Respondent implemented the change as permitted under the CBA, Section 4.2."

2. Assert all affirmative defenses — These are legal reasons why, even if the allegations are true, no violation occurred. Common defenses:

   • Action was taken for a legitimate, non-retaliatory business reason
   • No exclusive bargaining obligation existed (the matter was not a mandatory subject of bargaining)
   • The union waived the right to bargain (by explicit language or past practice)
   • The disputed action was authorized by the existing CBA
   • Insufficient evidence of management knowledge or intent
   • Laches (unreasonable delay in filing the charge)

3. Explain the context and your reasoning — Do not make your answer a dry list of denials. Explain why you took the action you did. For example:

   "The allegation mischaracterizes the chronology. In May 2024, the Superintendent tasked the Finance Director with modeling the cost impact of a proposed 3% salary increase over three years. The Finance Director prepared a cost analysis showing that a 3% annual increase would require a 2.1% increase in the district's property tax levy, in accordance with the Uniform Unfunded Mandates Act. On June 12, 2024, the Superintendent presented this analysis to the Board in open session and sought Board authorization to propose this increase to the Union. This was a transparently deliberative process that occurred before any offer was made to the Union. The allegation conflates internal cost analysis with an improper unilateral decision."

4. Cite the CBA and relevant law — Ground your answer in contractual language and statute. Vague assertions do not help.

5. Request a hearing if the charge is not settled — Your answer should conclude with a statement that you deny the charges and request a full hearing if settlement is not achieved.

Common Mistakes That Destroy Defensibility

• Over-explaining or changing the narrative: Stick to what actually happened. Do not embellish or rationalize.
• Admitting facts you can credibly deny: If an email could support either interpretation, deny it and let the evidence sort it out at hearing.
• Contradicting prior statements: If a board member or superintendent made a public statement, do not contradict it in your legal answer. It will be used against you.
• Ignoring procedural requirements: File on time, in the correct format, to the correct office, with proof of service on the union.
• Making threats or inflammatory language: Keep your tone neutral and professional throughout.

Cost and Liability Exposure

Direct Costs of a ULP Charge

Liability Exposure

If the NLRB or state agency finds a violation, you may be ordered to:

• Back pay — Retroactive compensation with interest, calculated from the date of violation to the date of remedy. For a terminated employee earning $75,000/year with benefits fully loaded at 1.35x cost multiplier, a 2-year back pay award = $201,750.
• Reinstatement — Restoration of the employee to their former position or equivalent role.
• Cease and desist order — Mandatory change in your policies or practices.
• Posting — Public notice of the violation and employee rights (typically 60 days in the workplace and online).
• Make-whole remedies — Restoration of benefits, seniority, pension contributions, or other benefits lost during the violation period.

For a refusal-to-bargain charge affecting a large unit, the exposure can be exponential. If you refuse to bargain over a compensation policy affecting 200 teachers, and the NLRB orders you to bargain retroactively, you may owe negotiated back pay for the entire unit — potentially $500,000–$2,000,000+.

Settlement Negotiations and Alternative Dispute Resolution

Most ULP charges settle before hearing. The settlement rate is approximately 60–70% across the NLRB system.

When Settlement Makes Economic Sense

Compare the cost-benefit of settlement versus fighting:

Settlement + Back Pay Path:

• Estimated back pay liability: $85,000
• Attorney fees (settlement): $18,000
• Total cost: $103,000
• Timeline: 4–8 months

Hearing Path:

• Estimated back pay liability (if you lose): $85,000
• Attorney fees (hearing + appeal): $65,000
• Expert witness costs: $8,000–$12,000
• Internal staff time: $10,000
• Total cost if you lose: $168,000–$172,000
• Timeline: 12–18 months
• Success rate: 40–50% (you're not guaranteed to win even with good facts)

If settlement is offered at $80,000–$95,000, it often makes financial sense to accept.

Negotiating a Settlement Agreement

A typical settlement includes:

1. Admission of no violation (in some cases) or admission of violation (in others) — This is highly negotiated.
2. Back pay calculation — Exact dollar amount, often with the union verifying employee hours and deductions.
3. Posting requirement — Notice to employees of their rights and the settlement.
4. Prospective remedies — Changes to your policies or procedures going forward.
5. Non-disparagement clause — Optionally, agreement not to publicize the settlement.
6. Expungement — In rare cases, agreement that the charge will not be cited in future disputes.

CollBar has worked with dozens of public-sector employers negotiating settlements of ULP charges. The key is understanding your liability exposure early and engaging the union in realistic negotiations once you understand what the evidence actually shows.

Preventing ULP Charges: A Checklist for HR and Management

The best response to a ULP charge is to avoid filing one in the first place. Here's a practical checklist:

Pre-Implementation Checklist for Any Significant Change

• Review the CBA — Does the change require bargaining? Is it a mandatory subject (compensation, benefits, hours, discipline standards)?
• Notify the union — Send a written notice describing the proposed change, the rationale, the timeline, and your availability to discuss.
• Provide relevant information — If the change involves cost, provide cost data. If it involves workload, provide supporting analysis.
• Document your proposal — Write out exactly what you're proposing, with specifics (dollar amounts, effective dates, scope of affected employees).
• Listen to the union response — Schedule a meeting. Hear their concerns. Take notes. Do not dismiss or minimize their position.
• Make a counter-offer or explain your final position — If the union proposes modifications, either accept them or explain why you cannot (cost, legal constraint, operational necessity).
• Allow reasonable time for negotiations — Do not implement before the union has had at least one full bargaining session to respond.
• Document the bargaining process — Keep email records, meeting notes, and a chronology of offers and responses.

Documentation Standards

For every significant labor relations action, your file should contain:

• Decision memo — Why the change was made, who made the decision, what alternatives were considered
• Bargaining record — Dates of union notifications, meetings, proposals, responses, final offers
• Cost analysis — If the decision was driven by budget, show the numbers: "Salary schedule increase 3% × 100 FTE × average $75,000 salary = $225,000 incremental cost in Year 1"
• Contemporaneous notes — Meeting minutes, email summaries, not post-hoc reconstructions
• Approval authority — Board resolution, superintendent authorization, finance sign-off

This documentation is your evidence. Without it, you're relying on memory and inference — and the NLRB will not credit that over the union's contemporaneous records.

State-Specific Variations

The NLRB covers private-sector employees and some public-sector workers (postal, airline, railroad). Most state and local government employees are covered by state-specific public-sector labor relations statutes, each with slightly different ULP processes.

Critical point: If your employees are covered by a state statute, you must file your answer with the state agency, not the NLRB, and deadlines and procedures differ. Confirm jurisdiction with your attorney immediately upon receiving a charge.

CollBar works with employers across multiple state jurisdictions and can help you navigate state-specific ULP procedures and align them with your labor negotiations strategy.

Frequently Asked Questions

What if we get served with a charge right in the middle of contract negotiations?

Negotiations do not stop. In fact, you are legally required to continue bargaining unless settlement talks explicitly involve the ULP allegation. Suspending negotiations because of a charge is itself potentially an unfair labor practice (refusal to bargain). Keep negotiating, document your proposals and responses, and handle the ULP investigation in parallel. Your attorney should coordinate with your negotiator to ensure consistency in messaging and strategy.

Can the union use the ULP charge to pressure us into accepting their contract proposal?

Yes — and they will. Filing a ULP charge is a negotiation tactic. It raises the cost and reputational risk to you, creates urgency, and gives the union additional leverage. This is legal. Your defense is to (a) have a strong defense to the charge, (b) understand your actual liability, and (c) not panic. The worst contracts are negotiated under crisis conditions. Separate the ULP from the contract. Defend the charge on its merits; negotiate the contract on its merits. CollBar helps employers keep these separate and make rational decisions about both.

What if a supervisor or board member makes a statement that contradicts our legal answer?

This is a disaster. The NLRB will use that statement against you. If a board member says in a public meeting "We decided to increase health insurance employee contributions to reduce our budget," but your legal answer says the decision was driven by market benchmarking, you have a credibility problem. Before your attorney files your answer, vet it with all decision-makers. If statements have already been made, consult your attorney about whether your answer can include explanation or context. Do not contradict prior statements; explain them if possible.

Can we appeal an unfavorable ALJ decision?

Yes. Either party can appeal an Administrative Law Judge's decision to the NLRB Board in Washington. This is a paper-based appeal (you submit a brief, the other party responds). The Board reviews the record for errors of law and substantial evidence. However, appeals are expensive ($15,000–$35,000 in attorney fees) and the Board reverses ALJ decisions only about 20–30% of the time. Appeal only if you have a strong legal argument, not a disagreement about facts.

What happens if we ignore the charge and do not file an answer?

You will lose. The NLRB or state agency will find the allegations true by default. The respondent (you) will be ordered to cease and desist, post notice, and pay full remedies (back pay, reinstatement, etc.) without a hearing. You forfeit all opportunity to defend yourself. This is the worst possible outcome. File your answer on time, every time.

Should we try to settle the charge ourselves without a lawyer?

No. Your HR director or labor relations officer should not engage in settlement discussions without counsel present. Anything you say can be used against you, and the union's representative will try to extract concessions or admissions. Your attorney must lead settlement discussions and protect your interests. The cost of counsel is far less than a bad settlement or a full hearing loss.

Can we file a counter-charge against the union?

Yes. You can file your own ULP charge alleging that the union violated labor law — for example, by threatening employees, refusing to cooperate with discipline, or committing secondary boycotts. However, a counter-charge should be filed on its own merits, not as a tit-for-tat response. Consult your attorney about whether you have a colorable claim. Some employers file counter-charges to gain leverage; others find it merely escalates conflict. Evaluate strategically.

Key Takeaways

• A ULP charge is a formal government investigation — It is not a lawsuit, but it is serious. You have 20 calendar days to file a written answer, and missing this deadline results in default judgment against you.

• Preserve all documents immediately — The moment you're served, stop any document destruction, segregate emails and files from the relevant time period, and provide them to your attorney.

• Hire labor counsel with NLRB or state labor board experience — Do not respond to a ULP charge without legal representation. Your answer is filed under oath and becomes discoverable evidence.

• Settle strategically, not emotionally — Calculate your actual liability (back pay, benefits, attorney fees, timeline) and compare it to settlement cost. If settlement is 30–50% cheaper and faster, it's often rational to accept.

• Prevention is the best strategy — Document all bargaining, provide information the union requests, explain your reasoning for policy changes, and allow adequate time for negotiation. A well-documented, transparent bargaining process prevents ULP charges before they're filed.
