California reference check laws give a former employer a qualified right to share honest, job-related information about a past employee, while flatly prohibiting disclosure of salary history, most criminal record details, medical information, and protected characteristics. The rules pull from several statutes at once, and the exposure for getting them wrong runs from civil damages to misdemeanor charges. Say too much and you invite a defamation or privacy suit; stay silent about a known danger after giving a glowing reference, and you can be sued for negligent referral.
What a Former Employer Can Share Without Consent
Basic, verifiable employment facts are the safe zone: dates of employment, job title, and duties performed. These are objective, easily confirmed, and carry little legal risk.
Two other statements are also allowed without written authorization from the employee. A former employer can say whether the person is eligible for rehire, and that specific statement is protected from defamation claims under California law.1California Legislative Information. California Civil Code 47 – Privileged Publication or Broadcast And if the employee signed a written authorization for a more detailed reference, the employer can go further, but only within the scope the authorization actually covers. Anything beyond that written consent is off limits.
Performance feedback can also be shared when a prospective employer requests it, provided the comments are based on credible evidence and made without malice. That qualifier is where the qualified privilege comes in.
The Qualified Privilege for Job References
California Civil Code Section 47(c) protects employers from defamation liability for communications about an applicant’s job performance or qualifications made to someone the employer reasonably believes is a prospective employer. Three conditions have to line up: the prospective employer requested the information, the reference is based on credible evidence, and the communication is made without malice.1California Legislative Information. California Civil Code 47 – Privileged Publication or Broadcast
The privilege falls away in a few situations. Knowingly false statements are not protected. Volunteering damaging information nobody asked for is not protected. And the statute explicitly excludes speech targeting constitutionally protected activity, so a former employer who trashes someone for union organizing, political activity, or whistleblowing loses the privilege entirely.1California Legislative Information. California Civil Code 47 – Privileged Publication or Broadcast
Malice, in this context, generally means hatred, ill will, or a willingness to vex the former employee. A harsh reference grounded in documented performance problems will usually hold up. An embellished or fabricated one meant to sabotage the applicant will not.
Topics That Cannot Come Up
Salary History
Labor Code Section 432.3 bars any employer from seeking a job applicant’s salary history, orally, in writing, or through an agent, and the ban covers both compensation and benefits.2California Legislative Information. California Labor Code 432.3 For a reference check, that means the prospective employer cannot ask what the applicant earned, and the former employer should not volunteer it.
One narrow exception: if the applicant voluntarily and without prompting shares their own salary history, the prospective employer can consider that information in setting pay.2California Legislative Information. California Labor Code 432.3 “Without prompting” is doing real work in that sentence. Violations carry civil penalties of $100 to $10,000 per violation, assessed by the Labor Commissioner.3California Department of Industrial Relations. California Equal Pay Act
Criminal History
Labor Code Section 432.7 makes several categories of criminal information completely off limits, whether asked about, considered, or shared from any source:
- Arrests or detentions that did not result in a conviction, except for pending cases where the applicant is currently out on bail or on their own recognizance.
- Participation in any pretrial or post-trial diversion program.
- Convictions that have been judicially dismissed, expunged, or sealed under California law.
- Any juvenile court records, including arrests, adjudications, and dispositions from when the person was a minor.
The statute prohibits seeking this information “from any source whatsoever,” so a former employer who volunteers it during a reference call creates exposure for both sides of the conversation. Applicants can recover actual damages or $200, whichever is greater, plus costs and attorney’s fees. Intentional violations bring treble damages or $500, whichever is greater, and are also a misdemeanor.4California Legislative Information. California Labor Code 432.7
On top of that, California’s Fair Chance Act (Government Code Section 12952) bars employers with five or more employees from asking about conviction history on a job application or at any point before making a conditional offer. If a post-offer background check turns up a conviction and the employer wants to rescind, it must complete an individualized assessment weighing the nature and gravity of the offense, the time elapsed since it and any sentence served, and whether the conviction has a direct and adverse relationship to the specific job duties. The applicant is then entitled to a written preliminary notice, a copy of the background report, and at least five business days to respond.5California Legislative Information. California Government Code 12952
Medical Information
Under California’s Confidentiality of Medical Information Act, an employer cannot use or disclose medical information about an employee without a signed authorization, with only narrow exceptions for legal proceedings involving the employee’s health, benefit-plan administration, and emergency medical treatment.6California Legislative Information. California Civil Code 56.20 A reference check is not one of them. Health conditions, disabilities, workplace accommodations, and leave history should never appear in a reference.
Protected Characteristics
Federal and state anti-discrimination law prohibits discussing an applicant’s race, religion, national origin, sexual orientation, age, disability, or any other protected trait during a reference check. These characteristics have nothing to do with job qualifications, and raising them exposes both the former and prospective employers to discrimination claims.7U.S. Equal Employment Opportunity Commission. Prohibited Employment Policies/Practices
When Saying Too Little Also Creates Liability
Most employers worry about oversharing. California recognizes the opposite risk, too. In Randi W. v. Muroc Joint Unified School District, the California Supreme Court held that an employer who chooses to write a reference letter owes a duty not to misrepresent the facts if those misrepresentations would create a foreseeable, substantial risk of physical injury to third parties.8Justia Law. Randi W. v. Muroc Joint Unified School Dist. (1997)
The case involved school administrators who gave unreservedly positive references for an employee they knew had a history of sexual misconduct with students. The court called those letters “misleading half-truths” because they omitted material facts that qualified the praise. An employer is not required to give a substantive reference at all, but if it does, the reference cannot paint a picture that conceals a known danger.8Justia Law. Randi W. v. Muroc Joint Unified School Dist. (1997)
The practical takeaway: the safest path in a hard case is often to confirm only basic employment facts and decline to offer opinions. If a positive reference is given, though, serious misconduct relevant to the new role cannot be quietly left out, especially where the job involves vulnerable populations.
Blacklisting Is a Crime
Labor Code Section 1050 makes it a misdemeanor for any employer or its agent to prevent, or attempt to prevent, a former employee from getting a new job through misrepresentation. It applies whether the person was fired or left voluntarily.9California Legislative Information. California Labor Code 1050
A blacklisted employee can also sue civilly and recover treble damages, without waiting for any criminal prosecution.10California Legislative Information. California Labor Code 1054 Coded references count. If a reference contains any mark, sign, or other means of conveying information different from what the words themselves express, that alone is prima facie evidence of a violation. Internal codes or signals used to warn other employers away from a candidate sit squarely inside the statute.
Third-Party Background Checks: FCRA and ICRAA
When an employer runs its own reference calls in house, federal consumer-reporting law generally does not apply. The moment a third-party agency is hired to investigate a candidate, two overlapping statutes attach: the federal Fair Credit Reporting Act and California’s Investigative Consumer Reporting Agencies Act.
Under the FCRA, before obtaining a consumer report for employment purposes, the employer must give the applicant a clear, standalone written disclosure and get written authorization. The standalone requirement is strict; bundling the disclosure with a liability waiver invites statutory damages. If the report leads the employer to consider not hiring the applicant, a two-step adverse action process kicks in: a pre-adverse action notice with a copy of the report and a summary of rights, a reasonable dispute window, and only then a final adverse action notice.11Office of the Law Revision Counsel. 15 USC 1681b – Permissible Purposes of Consumer Reports
California’s ICRAA layers on more. Before obtaining an investigative consumer report for employment purposes, the employer’s standalone disclosure must identify the agency’s name, address, and telephone number, describe the nature and scope of the investigation, and include a summary of the applicant’s rights, all with written authorization from the applicant.12California Legislative Information. California Civil Code 1786.16 Meeting the ICRAA standard will usually satisfy the FCRA. The reverse is not always true.
Penalties Add Up Quickly
The consequences depend on which rule was broken, and they can stack.
- Defamation, invasion of privacy, and FEHA discrimination claims are uncapped and turn on the harm proven.
- Blacklisting under Labor Code 1050 is a misdemeanor, with treble civil damages available under Section 1054.9California Legislative Information. California Labor Code 1050
- Salary history violations carry $100 to $10,000 per violation in civil penalties, with a separate right to injunctive relief.3California Department of Industrial Relations. California Equal Pay Act
- Labor Code 432.7 violations bring actual damages or $200 for unintentional conduct, treble damages or $500 for intentional conduct, plus attorney’s fees, and intentional violations are a misdemeanor.4California Legislative Information. California Labor Code 432.7
- Fair Chance Act complaints can be investigated and enforced by the Civil Rights Department, including orders to change hiring practices.
- Willful FCRA noncompliance carries statutory damages of $100 to $1,000 per violation, with class action exposure for systemic failures.
Documenting what was asked, who answered, and what was said protects everyone. For a hiring employer relying on a reference to justify a decision, contemporaneous notes are often the strongest defense if the applicant later challenges the outcome.
