Union Organizing Rights in California: What Workers Can Do

The National Labor Relations Act (NLRA), enacted in 1935 (29 U.S.C. § 157), is the foundational federal law protecting union organizing rights in the United States. Section 7 of the NLRA gives employees the right to self-organize, form unions, bargain collectively through representatives of their choosing, and engage in concerted protected activities for mutual aid and protection. This applies to private-sector employees in interstate commerce, though railroads and airlines are covered under the Railway Labor Act instead.

Section 8 of the NLRA (29 U.S.C. § 158) defines unfair labor practices by employers. Specifically, employers cannot interrogate employees about union activities, conduct surveillance or threaten surveillance of union organizers, threaten employees with job loss or reduced hours if they unionize, promise benefits to discourage union activity, or take adverse employment actions because of union organizing. The law protects both active organizers and workers who simply participate in union meetings or discussions.

The National Labor Relations Board (NLRB), an independent federal agency, enforces the NLRA. The NLRB processes unfair labor practice charges, oversees union certification elections, and investigates violations. Remedies under federal law include reinstatement with back pay for wrongfully discharged workers, cease-and-desist orders against employer conduct, and posting of notices informing employees of their rights. Covered employers include those with sufficient interstate commerce nexus; most private employers meet this threshold.

California law reinforces and in some respects extends federal NLRA protections. California Labor Code section 923 explicitly protects employees from employer retaliation for union organizing and activity, stating that employers cannot threaten, discriminate against, or discipline workers because of their union membership or activities. This statute provides an additional layer of protection beyond federal law and creates state-level enforceability.

Most importantly, California's Agricultural Labor Relations Act (ALRA), codified in California Code sections 1140 et seq., extends union organizing and collective bargaining rights to agricultural workers who are excluded from federal NLRA coverage. Under the ALRA, agricultural employees have explicit rights to organize, strike, and bargain collectively. The ALRA is enforced by the Agricultural Labor Relations Board (ALRB), a state agency that mirrors NLRB procedures. This represents California's most significant enhancement of federal law in the union organizing context, as federal law explicitly carves out agricultural workers.

California courts have also interpreted state law to protect union activity under broader statutes. For example, California public policy, as expressed through the Labor Code, prohibits retaliation against workers who exercise statutory rights. Additionally, California recognizes claims for wrongful termination in violation of public policy when the termination is motivated by union activity.

While the NLRB has primary jurisdiction over most private-sector union organizing disputes in California, state law claims can proceed in California courts in parallel. California does not have right-to-work legislation; thus, union security clauses (requiring union membership or fee payment as a condition of employment) are enforceable in California private-sector agreements, subject to federal limitations. Public-sector employees in California are covered under different statutory schemes (MMBA, EERA, HEERA) and have distinct organizing rights and procedures.

Not all workers have union organizing rights under the NLRA. Supervisors, managers, and certain confidential employees are excluded from NLRA coverage and protections. Independent contractors are not protected; the NLRB uses a multi-factor test to distinguish employees from independent contractors, examining control, investment, permanency, and whether work is part of the employer's regular business. Domestic workers employed in private homes are excluded from the NLRA but may have limited protections under state law.

Federal employees are not covered by the NLRA; they have organizing rights only under the Federal Service Labor-Management Relations Act (FSLMRA). State and local government employees are also excluded from NLRA coverage. However, many state and local employees in California have organizing rights under California Government Code sections governing public-sector labor relations (the Meyers-Milias-Brown Act for local agencies, the Educational Employment Relations Act for school districts, and the Higher Education Employer-Employee Relations Act for public universities).

Employers have significant legal defenses and limitations on union organizer access rights. Employers can restrict union organizers from accessing company property if they provide reasonable alternative means of communicating with employees (such as providing contact information). In the landmark Lechmere case, the U.S. Supreme Court held that union organizers have no absolute right to access private property. Employers can also lawfully prohibit union discussions during work time if the prohibition applies equally to other non-work-related conversations.

Anti-union speech by employers is protected employer free speech under the First Amendment and NLRA Section 8(c), provided the speech contains no threat of reprisal or promise of benefit. Employers can express opposition to unionization, predict negative economic consequences, or encourage employees to vote against union representation, as long as such statements do not cross the line into threats or coercion. The NLRB distinguishes between protected employer commentary and unlawful interrogation or threats based on context and severity.

Step 1: Document the employer conduct. Keep detailed records of any employer interrogation (questions about union support, attendance at meetings, organizer contacts), surveillance or monitoring of union activities, threats or warnings about unionization consequences, disciplinary actions following union organizing activity, or promises of benefits conditioned on abandoning union support. Write down dates, times, witnesses, and exact words used. Retain emails, text messages, or written communications. Take screenshots of company intranet or bulletin boards showing anti-union messaging. This documentation becomes critical evidence in an NLRB investigation.

Step 2: Exhaust internal complaint procedures if available. Some employers have grievance procedures; filing an internal complaint creates additional documentation and may preserve evidence. However, internal complaints are not a legal prerequisite to filing with the NLRB. Inform trusted coworkers and union organizers of the violation. Contact union representatives who can advise on next steps and assist with organizing efforts. Union organizers often have experience identifying and documenting unfair labor practices.

Step 3: File an unfair labor practice charge with the NLRB. You have 180 days from the date of the violation to file. Visit www.nlrb.gov to locate your regional NLRB office (California has multiple regional offices: Region 20 in San Francisco covers Northern California; Region 21 in Los Angeles covers Southern California). You can file a charge online through the NLRB's system or in person at your regional office. The charge must include: your name and contact information, the employer's name and address, a detailed description of the unlawful conduct, the date(s) the violations occurred, and the names of witnesses. Include your documentation.

Step 4: Expect the investigation process. An NLRB investigator will contact you within days to weeks. The investigator will interview you, review your documentation, and gather evidence. The NLRB then typically interviews the employer and relevant witnesses. The investigation usually takes 30–60 days but can extend longer for complex cases. During this time, remain available to provide additional information. Do not discuss the investigation with coworkers beyond what is necessary for organizing purposes; the NLRB investigator will advise you of confidentiality expectations.

Step 5: Consult an employment attorney experienced in labor law if the violation is serious, if you were terminated, or if the employer is large and well-represented. Labor attorneys can provide representation before the NLRB, present evidence at hearings, and negotiate settlements. Many employment law firms offer free consultations. If the NLRB investigator determines the employer likely committed an unfair labor practice, the NLRB Regional Director issues a complaint. The case may proceed to a hearing before an NLRB Administrative Law Judge, followed by potential appeals. An attorney is invaluable in hearing preparation and strategy. Some attorneys take cases on contingency if remedies (back pay) are substantial.
