Can I join a union at my job?

This page covers unions and acting together at work. It is general information, not legal advice. For being punished for political activity or a protest, see Can my employer punish me for political activity or joining a protest.

Do I have the right to join a union?

Yes, for most workers. Federal law gives private sector workers the right to form, join or help a union, to bargain as a group, and to act together "for mutual aid or protection." You also have the right not to take part (NLRB, Section 7).

You do not need a union to be protected. When two or more coworkers act together about pay, hours, safety or treatment, that is often protected too. One worker speaking up for a group can count. See Can my employer punish me for political activity for more on group activity.

Your immigration status. The U.S. Supreme Court has said the federal labor law applies to undocumented workers. But it also said the NLRB cannot award back pay to a worker who was never authorized to work (Hoffman Plastic Compounds v. NLRB, 2002). That ruling was about back pay. The farmworker board says your immigration status does not matter for its help (ALRB). Talk to a clinic before you share anything about your status.

Which law covers my job?

Who federal labor law leaves out. The federal law does not cover farmworkers, domestic workers employed in a family's home, people employed by a parent or spouse, independent contractors, supervisors, or workers for railroads and airlines (which have their own law). It does not cover government workers either (29 U.S.C. 152).

If your boss calls you an independent contractor, you may still be an employee under the law. See Your rights at work.

What can my boss not do?

Under federal law, an employer may not interfere with your right to organize. Examples the NLRB gives include (NLRB):

• Threats of firing, lost benefits or worse conditions if you support a union
• Promises of rewards if you drop union support, or new benefits timed to sway a vote
• Spying on union activity, or acting as if they are watching it
• Pressing questions about your union views or your coworkers'
• Banning union talk during work time when other non-work talk is allowed
• Banning union buttons or shirts without special reasons
• Saying a union is pointless in a way that suggests it is futile
• Firing, discipline or schedule cuts for protected group activity

In California, threatening to report a worker to immigration because they used a work right is also illegal. Starting January 1, 2027, a new state law also bars using a worker's perceived immigration status in a way that would scare them out of using a right, even before they complain (AB 2495, Chapter 748, Statutes of 2026). See If your boss threatens to call immigration.

How do we start a union?

Many groups start by contacting an existing union that represents workers in their industry. The union can explain the steps and help. The official process for most private jobs works like this (NLRB, Conduct elections):

1. Show support. Workers sign cards or a petition. A petition for an election needs support from at least 30% of workers in the group.
2. File a petition with the nearest NLRB regional office, preferably online.
3. Notice goes up. The employer must post a notice about the petition.
4. Agree on details or have a hearing. Date, place, who can vote, and the ballot. If the sides do not agree, the regional director holds a hearing and can order an election.
5. Vote. The result is decided by a majority of votes cast.
6. Objections. Either side may object within 7 days of the count.
7. Certification. If the union wins, it is certified and the employer must bargain with it.

Another path: voluntary recognition. An employer can agree to recognize the union after it shows majority support, for example through signed cards. Then workers get a 45 day window to file for an election if they want one.

Farmworkers have their own process under California law. Contact the ALRB for the current steps. It runs a WhatsApp channel with updates in English, Spanish and Mixteco audio.

What changes once there is a union?

A union contract can set pay, schedules, benefits, and rules for discipline and firing. Without a contract, most California jobs are "at will." See Can my employer fire me for any reason?

The union negotiates for everyone in the group, members or not. Ask about dues and what they pay for before you join.

What if my union treats me unfairly?

A union must represent everyone it covers fairly, in good faith and without discrimination, whether or not they are members. This covers bargaining, handling grievances and running hiring halls (NLRB, Right to fair representation).

A union may not refuse to take your grievance because you criticized union leaders or are not a member. It also may not act in bad faith or treat workers differently because of race or another protected trait.

The duty has limits. It usually does not cover rights you can enforce yourself, like a workers' comp claim, or internal union rules.

What to do:

1. Ask your union rep, in writing, what they decided and why.
2. Keep copies of every message and the dates.
3. File a charge against the union with the NLRB (or ALRB or PERB, depending on your job). For the NLRB, the deadline is 6 months (29 U.S.C. 160(b)).
4. Get advice from a clinic quickly. Do not wait for the union to change its mind.

Common mistakes to avoid

• Organizing on work email, work chat or a work phone. Use personal devices and talk outside work hours.
• Missing the 6 month deadline. NLRB charges are short. File first, gather more later.
• Quitting in anger. You lose leverage. Get advice first.
• Assuming you are not covered. Some people called contractors or "managers" are employees under the law. Ask.

Questions people ask

Can I be fired just for talking about a union? For most private sector workers, no. Firing or punishing you for protected union activity is an unfair labor practice. File with the NLRB within 6 months.

Do I have to join the union to keep my job? Ask the union and read the contract. Rules on required membership and fees are complex and differ between private and public jobs. Get advice before you decide.

I work in someone's home as a nanny or housekeeper. Can I join a union? Federal labor law does not cover domestic workers employed in a family's home. You still have wage, break and safety rights under California law. See Your rights at work.

Can my boss hold meetings against the union? Employers often share their views. What they cannot do is threaten, promise rewards, spy, or punish. Write down anything that crosses that line.
