Yes, blacklisting is illegal in California. Labor Code Sections 1050 through 1054 make it a misdemeanor for a former employer to use misrepresentation to prevent, or even try to prevent, you from getting hired somewhere else, and the same statutes let you sue for three times whatever the blacklisting cost you.1California Legislative Information. California Code Labor Code 1050 – Reemployment Privileges2California Legislative Information. California Code Labor Code 1054 The Fair Employment and Housing Act adds a second layer when the blacklisting is tied to discrimination or retaliation.
What Counts as Illegal Blacklisting
Labor Code Section 1050 is the core rule. It makes it a misdemeanor for any employer, or any agent of an employer, to use misrepresentation to prevent or attempt to prevent a former employee from finding new work. The law covers workers who were fired and workers who quit.1California Legislative Information. California Code Labor Code 1050 – Reemployment Privileges
The “attempts to prevent” language does real work. Your old employer doesn’t have to succeed at killing a job offer. Lying to a prospective employer is enough, whether or not that lie actually costs you the position.
Section 1051 targets a quieter form of the same problem. It bars employers from requiring you or a job applicant to submit to photographing or fingerprinting when those records could be shared with other employers or third parties to your detriment. The statute exists to stop industry-wide identification databases used to screen workers out.3California Legislative Information. California Code Labor Code 1051
Section 1052 pushes liability up the chain. Anyone who knowingly permits a manager, supervisor, or employee to violate Sections 1050 or 1051, or who fails to take reasonable steps to prevent those violations, is also guilty of a misdemeanor.4California Legislative Information. California Code Labor Code LAB 1052 An owner cannot shrug off a vindictive manager who is sabotaging former employees. The law expects the company itself to shut that behavior down.
What a Former Employer Can Legally Say
Not every negative reference is unlawful. Section 1053 creates a safe harbor: an employer may give a truthful statement about why you were discharged or why you left, provided the prospective employer actually asked for that information.5California Legislative Information. California Code Labor Code 1053 If a hiring manager calls and your former boss honestly says you were let go for repeated no-shows, that’s protected.
Two things puncture the safe harbor. First, any hidden mark, sign, or code in a written reference that conveys something different from the words on the page is, by itself, prima facie evidence of a violation. Second, volunteering the information counts against the employer. If your former company proactively calls around to warn people about you, that unsolicited outreach can support a blacklisting claim even when the underlying statements are true.5California Legislative Information. California Code Labor Code 1053
California Civil Code Section 47(c) adds a qualified privilege for honest, good-faith references. Communications about a job applicant’s performance or qualifications are protected when the information rests on credible evidence, is made without malice, and is given at the request of someone the employer reasonably believes to be a prospective employer. The privilege specifically covers whether the employer would rehire you.6California Legislative Information. California Code Civil Code CIV 47 Malice destroys the privilege. A reference driven by spite loses its legal protection.
When Blacklisting Also Violates FEHA
The Fair Employment and Housing Act, at Government Code Section 12940, gives you a second theory. FEHA applies to employers with five or more employees and bars discrimination in hiring, firing, compensation, and other terms of employment based on protected characteristics. Those characteristics include race, sex, gender identity, age (40 and over), disability, sexual orientation, religion, national origin, marital status, medical condition, genetic information, reproductive health decisions, and veteran or military status, among others.7California Legislative Information. California Code GOV 12940 – Unlawful Employment Practices
If a former manager tells industry contacts not to hire you because of your disability, that conduct violates FEHA whether or not it also violates the Labor Code. Same for retaliation. If you filed a discrimination complaint, reported a safety violation, or exercised some other legal right, and your old employer answered by poisoning your job search, the retaliation itself is unlawful under FEHA.7California Legislative Information. California Code GOV 12940 – Unlawful Employment Practices Retaliation theories often carry the case, because a tight timeline between protected activity and a suddenly cold job market is powerful circumstantial evidence.
Non-Competes Are Not a Legitimate Reason
One question comes up often: can a former employer legally warn competitors off by pointing to a non-compete agreement? In California, no. Business and Professions Code Section 16600 voids any contract that restrains someone from engaging in a lawful profession, trade, or business, and the statute is written to be read broadly.8California Legislative Information. California Code Business and Professions Code BPC 16600
Legislation that took effect in 2024 went further. Section 16600.1 makes it affirmatively unlawful for an employer to include a non-compete clause in an employment contract, and required employers to notify current employees and former employees hired after January 1, 2022, in writing, that any existing non-compete clauses are void. Violating the notice requirement is an act of unfair competition.9California Legislative Information. Assembly Bill 1076 A former employer who threatens to enforce a non-compete against a company that wants to hire you is not just wrong on the law; that threat can itself look like the interference the blacklisting statutes were written to punish.
Penalties and What You Can Recover
Each violation of Sections 1050, 1051, and 1052 is a misdemeanor. The civil remedy is where the real leverage sits. Section 1054 makes anyone who violates those provisions liable to the injured person for treble damages, meaning three times what the blacklisting actually cost you. You do not need a criminal conviction first, and you do not need to wait for a prosecutor.2California Legislative Information. California Code Labor Code 1054
FEHA claims carry their own remedies: back pay, emotional distress damages, and, in some cases, punitive damages and attorney fee awards.
How to Prove It and Where to File
Blacklisting is hard to prove because it happens on phone calls you never hear. The strongest cases are built on pattern evidence. You are qualified, you are getting interviews, and offers keep evaporating after the reference check.
Build the Record
Save every application, every recruiter email, and every stated reason for rejection. If a recruiter mentions something odd your former employer said, write down the exact words and the date. Some applicants hire professional reference-checking services to call the old employer and record what is being said, which produces direct evidence when a company gives you a clean reference to your face and a different one behind your back.
Watch the timing. Rejections that cluster right after a discrimination complaint, a safety report, or a bad-terms departure support both a blacklisting and a retaliation theory.
Where to File
California offers two administrative routes:
- Labor Commissioner (DLSE). For Labor Code blacklisting violations, file a retaliation or discrimination complaint with the Division of Labor Standards Enforcement. Complaints generally must be filed within one year of the retaliatory act.10California Department of Industrial Relations. How to File a Retaliation or Discrimination Complaint
- Civil Rights Department (CRD). For blacklisting driven by discrimination or retaliation tied to a protected characteristic, file with the CRD. You generally have three years from the date of the discriminatory act.11California Civil Rights Department. Employment Discrimination
The CRD process begins with an online intake form or a call to 800-884-1684.12California Civil Rights Department. Complaint Process These deadlines are firm. Missing one can wipe out the claim. If more than one theory might apply, talk to an employment attorney early; the treble damages provision under Section 1054 is enough that many lawyers will take these cases on contingency.
