When Unions Send Age Bias Claims to Arbitration

In workplaces with unions, many employment rights are governed by a collective bargaining agreement (CBA) negotiated between the union and the employer. One of the most controversial developments in this area is the idea that a union can agree, in a CBA, that members must bring certain legal claims—such as age discrimination claims—through arbitration instead of filing a lawsuit in court. These agreements can dramatically change how older workers enforce their rights under the Age Discrimination in Employment Act (ADEA), the federal law that protects workers age 40 and older.

This article explains how Supreme Court decisions have shaped this issue, what it means when a union contract sends statutory discrimination claims to arbitration, and what rights workers still retain even when they cannot personally sue in court.

Key Concepts: ADEA, Unions, and Arbitration

Before diving into specific court decisions, it helps to understand three foundational concepts that interact in this area of law.

The Age Discrimination in Employment Act (ADEA)

The ADEA is a federal statute that:

• Protects workers who are 40 years of age or older from discrimination on the basis of age.
• Covers decisions about hiring, firing, pay, promotions, benefits, and other terms and conditions of employment.
• Applies to most employers with at least 20 employees, and to federal, state, and local governments.[10]

Historically, age discrimination claims were often litigated in court, and workers could seek remedies such as back pay, reinstatement, and sometimes liquidated damages if they proved a willful violation.

What a Collective Bargaining Agreement Does

A collective bargaining agreement is a contract between a union and an employer that sets out the terms and conditions of employment. Common subjects include:

• Wages and benefits
• Work schedules and overtime rules
• Seniority systems and promotion procedures
• Discipline and discharge standards
• Grievance and arbitration processes for workplace disputes

Under the National Labor Relations Act, unions have authority to negotiate over a wide range of topics, including how certain disputes are resolved. The controversy arises when that bargaining includes statutory rights, such as the right to be free from age discrimination under the ADEA.

Arbitration Compared to Court

Arbitration is a private dispute resolution process in which one or more neutral arbitrators hear the case and issue a binding decision. Some key differences from court litigation include:

• Forum: Arbitration hearings typically occur in conference rooms rather than public courtrooms.
• Procedures: Discovery and procedural rules are usually more limited and streamlined than in court.
• Appeals: There is very limited ability to appeal an arbitrator’s decision, even if the arbitrator may have made legal errors.
• Privacy: Proceedings and outcomes are often confidential, unlike many court cases.
• Speed and cost: Employers and unions often prefer arbitration because it can be faster and less expensive than litigation.

Whether arbitration is better or worse for individual employees depends on the specific procedures in the agreement, the quality of union representation, and the facts of the case.

How the Supreme Court Opened the Door to Union-Mandated Arbitration

For many years, there was uncertainty about whether a union could agree that its members must arbitrate statutory discrimination claims. Earlier Supreme Court cases indicated that employees who pursued arbitration under a collective bargaining agreement could still sue in court later for discrimination.[10] But in more recent decisions, the Court has recognized the enforceability of arbitration agreements that cover ADEA claims.

The Shift Toward Enforcing Arbitration of Discrimination Claims

Two strands of Supreme Court doctrine laid the groundwork:

• Individual agreements: The Court had already held that individual employees who signed arbitration agreements with their employers could be compelled to arbitrate ADEA claims instead of going to court.[10]
• Federal policy favoring arbitration: The Court repeatedly emphasized that federal law strongly favors arbitration when parties have clearly agreed to it, including for statutory claims.

Building on these principles, the Court eventually addressed whether the same logic applied when the arbitration commitment arose not from an individual contract but from a union-negotiated collective bargaining agreement.

Union Power to Channel ADEA Claims to Arbitration

In a key ruling involving a building services union, the Supreme Court held that a collective bargaining agreement that “clearly and unmistakably” requires union members to arbitrate ADEA claims is enforceable as a matter of federal law. According to the Court, nothing in the ADEA prohibits arbitration of age discrimination claims, and the union and employer may agree to this as part of their bargaining relationship.

As a result:

• When the CBA explicitly states that age discrimination claims must be resolved through arbitration, employees covered by that agreement can be required to arbitrate instead of filing an individual lawsuit in court.
• The decisive factor is whether the waiver of a judicial forum for statutory claims is “clear and unmistakable” in the agreement.
• The Court reasoned that Congress did not restrict the bargaining authority of unions on this issue when it passed the ADEA.

This decision marked the first time that the Court expressly upheld a union’s ability to commit employees to arbitrate federal discrimination claims through a collective bargaining agreement.

What Rights Do Workers Keep Under These Agreements?

Even when a union contract requires arbitration of age discrimination claims, workers do not lose all avenues for protection. Several important rights remain.

The Right to File a Charge with the EEOC

The Supreme Court has held that an arbitration agreement does not prevent the federal Equal Employment Opportunity Commission (EEOC) from enforcing discrimination laws in court. Even if an individual cannot personally sue, the EEOC may still:

• Receive and investigate charges of age discrimination.
• Attempt to resolve the dispute through conciliation.
• File its own lawsuit in federal court and seek relief such as injunctive orders or policy changes.

However, if the employee is bound by an arbitration agreement, the EEOC’s court action may be limited in the types of monetary remedies it can obtain on the worker’s behalf.

Standards for Proving Age Discrimination Still Apply

Requiring arbitration does not change the basic legal standard for proving age discrimination. Under Supreme Court precedent, workers generally must show that age was a “but-for” cause of an adverse employment action in order to obtain monetary relief under the ADEA. That means the worker must prove that the adverse decision would not have occurred but for the worker’s age.

For federal-sector employees, the Court has clarified that any consideration of age in the decision-making process violates the statutory requirement that personnel actions be “free from any discrimination based on age,” even if age is not the but-for cause of the ultimate outcome. In those cases, workers may still be able to obtain forward-looking remedies, such as orders preventing future discrimination, even if back pay or reinstatement is not available.

Waivers and Severance Agreements in Age Cases

Separate from collective bargaining agreements, older workers often encounter waivers of age discrimination claims in severance or early retirement packages. The EEOC has issued detailed rules on such waivers to ensure they are knowing and voluntary. Among other things:

• Employers must follow specific procedural safeguards when asking workers to waive ADEA claims, such as giving adequate time to consider the agreement.
• Waiver documents often include a “covenant not to sue”, but the EEOC generally treats such covenants the same as releases, requiring compliance with ADEA waiver regulations.
• Older workers who challenge the validity of a waiver may be allowed to keep severance pay while pursuing an ADEA claim; they are not required to return the money as a condition of filing suit.

These rules highlight that even when employers or unions seek to limit court access, federal law imposes safeguards to protect older workers from unfair or coercive waivers of their rights.

Practical Implications for Unions, Employers, and Workers

The enforceability of arbitration clauses for ADEA claims has practical consequences for all parties involved in collective bargaining.

For Unions

• Unions must weigh the trade-offs between efficiency and members’ access to a judicial forum.
• Including a broad arbitration clause may speed resolution of disputes and avoid costly litigation but may also limit individual members’ direct access to courts.
• Unions have a duty of fair representation; they must handle members’ discrimination grievances without discrimination or bad faith when arbitration is the exclusive remedy.

For Employers

• Employers may view arbitration provisions as a way to gain more predictability and control over litigation costs.
• They must ensure that CBA language is explicit if they want to channel statutory discrimination claims to arbitration—vague or general language is unlikely to suffice.
• Even with arbitration, employers remain subject to EEOC investigations and enforcement actions.

For Individual Workers

• Employees should understand whether their CBA includes a clear and unmistakable arbitration clause covering statutory discrimination claims, including age discrimination.
• They should know how to use the grievance and arbitration process, including deadlines, documentation, and the role of union representation.
• They still have a right to file an EEOC charge and may receive some remedies even if their personal claim must proceed in arbitration rather than court.

Frequently Asked Questions (FAQs)

1. Can my union really waive my right to sue in court for age discrimination?

Under Supreme Court precedent, a union can agree in a collective bargaining agreement that ADEA claims will be resolved through arbitration rather than in court, if the contract clearly and unmistakably says so. The Court found no provision in the ADEA that forbids this kind of agreement, as long as the arbitration clause is explicit.

2. Does arbitration mean I have fewer legal protections?

The underlying substantive rights under the ADEA remain the same in arbitration and in court—the employer cannot lawfully discriminate based on age. However, the procedures are different: discovery may be more limited, evidentiary rules may be looser, and appeal rights are narrower. Whether that is better or worse for a particular worker depends on the facts of the case and the quality of representation.

3. Can I still file a charge with the EEOC if I have to arbitrate?

Yes. The Supreme Court has held that arbitration agreements do not prevent the EEOC from accepting charges, investigating, or bringing enforcement actions, even if the worker is bound to arbitrate. However, the types of monetary remedies the EEOC can obtain for the individual may be constrained by the arbitration commitment.

4. Do these rules apply to federal government employees?

Federal-sector employees are covered by a specific ADEA provision that requires personnel actions to be “made free from any discrimination based on age.” The Supreme Court has interpreted this language to mean that age cannot play any role in the decision-making process, even if it is not the but-for cause of the ultimate decision. Questions about arbitration and collective bargaining for federal workers can involve additional statutes and regulations, so federal employees should seek advice tailored to their sector.

5. If I signed a severance agreement, can I still bring an age discrimination claim?

It depends on whether the waiver meets the ADEA’s strict requirements and on how the EEOC’s regulations apply in your situation. The EEOC has made clear that older workers can, in some circumstances, accept severance pay and still challenge the validity of a waiver, without first returning the money. But this is a complex area, and the language of your particular agreement matters a great deal.

What to Do If You Suspect Age Discrimination in a Union Workplace

If you believe you have experienced age discrimination and you are covered by a collective bargaining agreement, consider the following steps:

• Review your CBA: Look closely at the grievance and arbitration provisions and any references to statutory claims, discrimination, or the ADEA.
• Consult your union representative: Ask about deadlines for filing grievances, how arbitration works in your workplace, and what support the union provides.
• Document events: Keep records of incidents, performance evaluations, communications, and any statements that may be relevant to your claim.
• File a grievance if required: If the CBA mandates arbitration, timely filing a grievance is often a necessary first step.
• Consider filing an EEOC charge: Even if you must arbitrate, filing a charge can preserve your rights and may lead to separate EEOC enforcement.
• Seek legal advice: An employment lawyer can help you interpret the CBA, evaluate your options, and decide how best to proceed.

Understanding how collective bargaining agreements interact with federal anti-discrimination law is crucial for older workers, unions, and employers alike. Supreme Court decisions have confirmed that unions can, in carefully drafted agreements, send age discrimination claims to arbitration, but they have not erased the core protections against age bias or the role of agencies like the EEOC in enforcing those protections.
