If a union already represents workers at your job, joining is usually a matter of contacting a union steward and signing a membership agreement. If no union exists yet, the path to joining a union is longer: you build support among coworkers by collecting signed authorization cards, file a petition with the National Labor Relations Board, and win a secret-ballot election. Which route applies to you depends on your workplace, and whether you’re eligible at all depends on your job category.
When a Union Already Represents Your Workplace
This is the short version of the story. Find the union steward on your shift or in your department, ask for a membership application, and sign it. The union will explain what dues you’ll pay and when they start coming out of your paycheck. You’re already covered by the collective bargaining agreement from the day you become an eligible employee in the bargaining unit; signing up formalizes your membership, your voting rights inside the union, and your access to member services.
What you owe financially depends on your state, and that question is covered further down.
Are You Eligible to Join?
The National Labor Relations Act covers most private-sector workers, but several categories fall outside its protections. You are not eligible for union representation under the NLRA if you are an independent contractor, an agricultural laborer, a domestic worker employed in someone’s home, or someone employed by a parent or spouse.1Office of the Law Revision Counsel. 29 USC 152 – Definitions Workers covered by the Railway Labor Act have their own separate framework and are also excluded from the NLRA.
Supervisors and managers cannot be in a bargaining unit either. The law defines a supervisor broadly as anyone with authority to hire, fire, promote, discipline, or direct other employees when that authority requires independent judgment rather than following a script.2National Labor Relations Board. National Labor Relations Act – Section 2 The NLRB looks at what you actually do, not your title. If your business card says “team lead” but you spend your day doing the same tasks as everyone else without real authority over staffing or discipline, you likely still qualify.
Contractors and Gig Workers
One of the biggest eligibility fights is whether someone is an employee or an independent contractor. If you’re classified as a contractor, you have no right to unionize under the NLRA, and many workers labeled as contractors actually function like employees.
The Department of Labor proposed new rules in early 2026 for determining worker classification under the Fair Labor Standards Act, centering on whether a worker is economically dependent on the employer or genuinely running their own business.3Federal Register. Employee or Independent Contractor Status Under the Fair Labor Standards Act, Family and Medical Leave Act, and Migrant and Seasonal Agricultural Worker Protection Act Two factors carry the most weight: how much control the employer exercises over scheduling and methods of work, and whether the worker has a genuine opportunity to profit or lose money based on their own business decisions. The NLRB uses its own related but distinct analysis for NLRA coverage. If you’re a gig worker or freelancer unsure about your status, resolving classification is worth doing before you try to organize, because the employer will almost certainly raise it as a defense.
Federal, State, and Local Government Workers
The NLRA applies only to private-sector workers. If you work for the federal government, your organizing rights come from the Federal Service Labor-Management Relations Statute. That statute grants federal employees the right to form and join unions, but it excludes members of the uniformed services, management officials, confidential employees, and anyone engaged in intelligence, counterintelligence, or national security work.4Office of the Law Revision Counsel. 5 USC Chapter 71 – Labor-Management Relations Federal unions also cannot negotiate over pay the way private-sector unions can, because Congress sets federal pay scales.
State and local government employees fall under their own state’s public-employee labor laws, and coverage varies widely. Some states grant full collective bargaining rights to teachers, firefighters, and other public workers; others restrict or prohibit public-sector bargaining. Check your state’s public-employee relations statute to see where you stand.
Starting a Union Where None Exists: Authorization Cards
When no union currently represents your workplace, the first concrete step is collecting authorization cards. Each card records an employee’s name, employer, job title, signature, and the date signed. A signed card tells the NLRB that the worker wants union representation.5National Labor Relations Board. Your Right to Form a Union
Most campaigns involve reaching out to an established union, such as the Teamsters, SEIU, or a trade union in your industry. Organizers from that union usually provide the cards and help coordinate the effort. Some campaigns start internally among coworkers before any union is contacted. Either approach works, but connecting with an existing union early gets you experienced organizers who know the legal process and common employer tactics.
You need at least 30% of the workers in your proposed bargaining unit to sign cards before you can petition for an election.6National Labor Relations Board. Basic Guide to the National Labor Relations Act Experienced organizers almost always aim well above that, often 60% or 70%, before filing. The 30% bar only gets you an election. Winning the election requires a majority of those who actually vote, and support tends to erode between card-signing and election day once the employer’s campaign against the union ramps up.
Filing a Petition with the NLRB
Once you have enough signed cards, the union (or the employees themselves) files a petition with the NLRB. The form is NLRB-502, specifically the “RC” version for certification of a representative.7National Labor Relations Board. Steps for Filing a Petition You file it with the regional office that covers the employer’s geographic area, electronically or by mail.
The petition must include the names of the union and the employer, along with a description of the bargaining unit. That unit description matters more than people realize. It defines which job classifications are included or excluded, and disagreements over unit composition are among the most common sources of delay. The NLRB reviews the proposed unit to confirm it’s appropriate for collective bargaining, weighing factors like shared working conditions, supervision, and job functions.8National Labor Relations Board. National Labor Relations Act – Section 9
After receiving the petition, NLRB agents verify the showing of interest by comparing signed cards against an employee list from the employer.6National Labor Relations Board. Basic Guide to the National Labor Relations Act If the cards don’t hit 30%, the petition is usually dismissed or withdrawn until more support is gathered. The employer also provides a voter list with names, job classifications, shifts, and work locations so the union can communicate with eligible voters before the election.9National Labor Relations Board. NLRB Representation Case-Procedures Fact Sheet
The Election and Getting Certified
After the petition clears review, the NLRB works with the employer and union to set election terms. Ideally the parties reach an election agreement specifying the date, time, and location of the vote. If they can’t agree, the regional director holds a hearing and then issues a direction of election.10National Labor Relations Board. Main Steps in the Representation Case Process Voting usually happens at the worksite by secret ballot, though mail-in ballots are used when workers are spread across multiple locations or shifts.
The union wins if it gets more than half of the votes cast. That’s a majority of those who actually vote, not a majority of the whole bargaining unit. If 100 employees are eligible but only 60 vote, 31 “yes” votes are enough. That math cuts both ways: low turnout can help or hurt the union depending on which side stays home.
Expect the process to take roughly three to eight weeks from petition to election, depending on whether the employer contests the unit description or raises other procedural objections. After the vote, either side can file objections to how the election was conducted. If no valid objections are sustained, the NLRB issues a Certification of Representative, the official confirmation that the union is now the exclusive bargaining agent for the unit.5National Labor Relations Board. Your Right to Form a Union At that point, the employer is legally required to bargain in good faith with the union over wages, hours, and working conditions.11Office of the Law Revision Counsel. 29 USC 158 – Unfair Labor Practices
Voluntary Recognition Without an Election
An election isn’t the only route. If a majority of employees sign authorization cards, the employer can voluntarily recognize the union without going through the NLRB election process.5National Labor Relations Board. Your Right to Form a Union Some employers do this to avoid a drawn-out campaign, particularly when support is overwhelming and fighting it would damage workplace morale.
In 2023, the NLRB announced a framework in its Cemex Construction Materials decision that changed the stakes. Under that framework, when a union presents evidence of majority support, the employer must either recognize the union or promptly file its own petition for an election. If the employer chooses an election but commits unfair labor practices serious enough to taint the results, the Board can order recognition without re-running the vote.12National Labor Relations Board. Board Issues Decision Announcing New Framework for Union Representation Proceedings NLRB policy can shift between administrations, so specific applications may evolve.
Your Protections While Organizing
Federal law makes it illegal for your employer to punish you for organizing activity. Your employer cannot fire, demote, transfer, or otherwise retaliate against you for trying to form a union, signing an authorization card, or encouraging coworkers to support one.11Office of the Law Revision Counsel. 29 USC 158 – Unfair Labor Practices Employers also cannot interrogate you about your union sympathies, spy on organizing meetings, or threaten to close the business if workers unionize.
Employers are allowed to share opinions about unionization, including arguments against it, as long as those statements contain no threats or promises of benefits.11Office of the Law Revision Counsel. 29 USC 158 – Unfair Labor Practices The line between a “prediction” and a “threat” gets litigated constantly. An employer saying “I worry this plant won’t be competitive with union wages” is probably legal speech. An employer saying “If you vote yes, I’ll move production overseas” likely crosses the line.
If your employer violates these rules, you can file a charge using NLRB Form 501 with the regional office covering your area. You have six months from the date of the violation to file.13National Labor Relations Board. Important Information Before Filling Out a Charge Form The form only needs a brief description of what happened, and the regional office’s information officer can help you draft it. You’re also responsible for serving a copy of the charge on the employer or union you’re filing against.
What Dues Will Cost You
Union dues fund contract negotiation, grievance handling, legal representation, and administrative costs. The amount varies by union and local, but it’s typically a fixed monthly amount or a percentage of wages.
Whether you can be required to pay dues depends on where you work. Roughly half of all states have right-to-work laws that prohibit making union membership or dues payment a condition of employment. In those states, you can benefit from the union’s contract without paying anything. In states without right-to-work laws, your employer and union can negotiate a “union security” clause requiring all workers in the bargaining unit to pay at least a portion of dues as a condition of continued employment.
Even in states that allow mandatory dues, you have options. A Supreme Court ruling known as the Beck decision gives you the right to pay only the share of dues used directly for representation, like contract negotiation and grievance administration, rather than the full amount that might also fund political activity or other non-representational spending. Workers who exercise this option are called “objectors.” You give up full union membership but you’re still covered by the contract. Unions are required to inform all covered employees about this option. If you have religious objections to union membership, you can direct an amount equal to dues to a nonreligious charity instead.14National Labor Relations Board. Union Dues
For public-sector employees, the 2018 Supreme Court decision in Janus v. AFSCME prohibits mandatory agency fees nationwide, regardless of state law. Public-sector workers cannot be required to pay any dues or fees to a union they choose not to join.
