To join a union, you either sign a membership application at a workplace that already has one, or you organize with coworkers, gather signed authorization cards from at least 30% of the proposed bargaining unit, and petition the National Labor Relations Board for a representation election. Which path applies to you is the first thing to figure out, because the paperwork for joining an existing union takes one pay cycle and organizing a new one takes months of coordinated work.
Are You Eligible to Join Under Federal Law
Section 7 of the National Labor Relations Act gives most private-sector employees the right to form, join, or assist a labor organization and to bargain collectively.1National Labor Relations Board. Interfering With Employee Rights (Section 7 and 8(a)(1)) The Act carves several groups out of its definition of “employee,” and if you’re in one of them, the NLRB has no jurisdiction over your organizing:2Office of the Law Revision Counsel. 29 US Code 152 – Definitions
- Supervisors with authority to hire, fire, promote, discipline, or direct other employees using independent judgment
- Independent contractors
- Agricultural laborers
- Domestic workers employed in a private home
- Workers employed by a parent or spouse
- Railroad and airline employees, who are covered by the Railway Labor Act instead
Public-sector workers sit outside the NLRA entirely. Federal employees organize under the Federal Service Labor-Management Relations Statute, and state and local government employees follow their own state’s public-employee labor relations law. If you work for a government employer, the steps below don’t apply to you and you’ll need to look at your state statute.
Joining a Union That Already Represents Your Job
When a contract is already in place, joining is mostly paperwork. Ask the shop steward, the coworker who acts as the union’s on-site representative, for a membership application and a dues check-off authorization. The check-off form directs your employer to deduct union fees from your paycheck and forward them to the union. Some employers hand these forms out during new-hire orientation.
Once the union processes your application and payroll starts the deduction, you’re a member in good standing. That lets you vote on contract ratification, elect union officers, and attend meetings. It usually takes one pay cycle.
What You’ll Pay Depends on Your State
Section 14(b) of the Labor Management Relations Act lets states pass right-to-work laws that prohibit requiring union membership or fee payments as a condition of employment.2Office of the Law Revision Counsel. 29 US Code 152 – Definitions Twenty-seven states currently have such laws. In those states you can work in a unionized shop, get the benefits of the contract, and pay nothing. The union is still legally required to represent you in grievances and negotiations.
In states without a right-to-work law, a collective bargaining agreement can require everyone in the bargaining unit to pay fees to the union as a condition of continued employment. You can decline full membership, but you can be required to pay the share of dues that covers representation.
Objecting to Political Spending
Even where fees are required, the Supreme Court held in Communications Workers of America v. Beck that non-members cannot be forced to fund union activities unrelated to collective bargaining. Compulsory fees can only cover negotiating and administering the contract, handling grievances, and similar representational work.3Cornell Law School. Communications Workers of America v Harry E Beck Jr et al If you object to paying for lobbying, political campaigns, or organizing at other companies, you can notify the union in writing and request a reduced fee limited to representational costs.
Religious Objections
If your sincerely held religious beliefs prohibit supporting labor organizations, 29 U.S.C. § 169 provides an accommodation. You cannot be required to pay dues; instead, the contract may require you to contribute an equivalent amount to a tax-exempt charity of your choice from a list of at least three options designated in the agreement.4Office of the Law Revision Counsel. 29 US Code 169 – Employees With Religious Convictions Payment of Dues and Fees
Starting a Union Where None Exists
If no union represents your workplace, joining means building one. Most drives start by contacting an established national or international union that organizes workers in your industry. That parent union provides authorization cards, trains volunteer organizers, and supplies legal guidance.
Authorization Cards and the 30% Threshold
The authorization card is the foundation of the campaign. It’s a signed statement that the employee wants the union to represent them, and each card should include the signer’s name, signature, date, and enough information to confirm they belong in the proposed bargaining unit.5National Labor Relations Board. Your Right to Form a Union
You need at least 30% of the employees in the proposed bargaining unit to sign before the NLRB will schedule an election.6National Labor Relations Board. Steps to Forming a Union Flyer Experienced organizers aim well above 50% before filing, because support tends to soften between the card drive and the vote. Filing at the bare minimum is how campaigns lose.
Electronic signatures count. NLRB General Counsel guidance from 2015 established that digital signatures carry the same weight as handwritten ones, as long as the submission includes the signer’s name, contact information, the language agreed to, the date signed, and the employer’s name, and the submitting party can show the signatures are authentic.
Defining the Bargaining Unit
Before filing, you have to define the bargaining unit: the specific group of employees the union will represent. The NLRB requires that everyone in a unit share a “community of interest,” meaning broadly similar duties, working conditions, supervision, and locations. A unit might be all full-time production employees at a single facility, excluding office staff and supervisors. Employers routinely challenge unit definitions as a delay tactic, so working through this with an experienced organizer or labor attorney matters.
Petitioning the NLRB and Winning the Election
With cards in hand, file a petition on Form NLRB-502 (RC), which stands for Representation–Certification. You can e-file, fax, hand-deliver, or send it by overnight mail to the NLRB regional office that covers your workplace.7National Labor Relations Board. Steps for Filing a Petition The petition goes in with the authorization cards or other proof of employee support, and copies must be served on the employer and any other involved labor organization.
An NLRB agent then verifies the signatures and reviews whether the proposed unit is appropriate. If there are disputes about who belongs in the unit, the regional director may hold a pre-election hearing.
If the petition clears review, the NLRB schedules a secret-ballot election at the workplace. The union wins on a simple majority of the votes actually cast, not a majority of eligible employees. If 100 workers are eligible but only 60 vote, 31 yes votes carry it.8National Labor Relations Board. Decertification Election Either side can object to the results if they believe misconduct affected the outcome. If the union wins, the NLRB certifies it as the exclusive bargaining representative for everyone in the unit, and the employer is legally obligated to negotiate a contract in good faith.
Voluntary Recognition
An election isn’t the only route. If the card majority is overwhelming, an employer can voluntarily recognize the union without a vote and move straight into contract negotiations.5National Labor Relations Board. Your Right to Form a Union This happens more often than people expect, particularly when the employer sees no point in contesting a vote it would lose.
What Your Employer Cannot Do While You Organize
Section 8(a) of the NLRA makes it an unfair labor practice for an employer to interfere with, restrain, or coerce employees exercising their Section 7 rights.9Office of the Law Revision Counsel. 29 US Code 158 – Unfair Labor Practices Organizers use the acronym TIPS for the four categories of prohibited conduct:
- Threatening workers with lost benefits, harsher conditions, or a plant closure if they unionize
- Interrogating employees about their union sympathies or who signed cards
- Promising raises, promotions, or other perks to discourage support, or suddenly soliciting grievances to make the union look unnecessary
- Surveilling union meetings or organizing activity, or creating the impression management is watching, including photographing or recording peaceful union activity
Employers can share their opinion that a union isn’t necessary. They cannot cross into coercion.1National Labor Relations Board. Interfering With Employee Rights (Section 7 and 8(a)(1))
Filing an Unfair Labor Practice Charge
Anyone can file an unfair labor practice charge on Form NLRB-501 at the regional office covering the workplace, electronically, by mail, by fax, or in person.10National Labor Relations Board. Charge Against Employer The deadline is six months from the date you became aware of the violation. Miss that window and the NLRB cannot issue a complaint, regardless of how clear the violation was.
An NLRB agent investigates the charge. If the regional director finds merit, the agency issues a complaint and may seek remedies including reinstatement of fired workers, back pay, and orders to stop the illegal conduct. During an active campaign, charges can also delay an election or invalidate the results if employer misconduct tainted the vote.
Winning the Vote Is Not the Same as Getting a Contract
Certification means the employer must bargain in good faith. It does not guarantee an agreement. A study of elections from 2018 found that 63% of newly certified unions had no contract after one year, and 43% were still without one after two. An analysis covering 2005 through 2022 found the average time from election to ratified contract exceeded 465 days.
No legal deadline forces either side to close a deal, only the obligation to bargain in good faith. Employers sometimes drag negotiations out hoping support will erode. The NLRB can pursue surface-bargaining charges when a party is going through the motions with no real intent to reach agreement, but the proof is hard and the process is slow. If you’re organizing, tell your coworkers this from the start so nobody thinks the work ends on election day.
