California Reference Check Laws: Privilege, Limits, and Penalties

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 records, medical information, and protected characteristics. The framework pulls from several statutes at once, and the penalties for crossing a line range from civil damages to misdemeanor charges. Employers sit in a real squeeze: say too much and face a defamation or privacy claim, say too little about a dangerous former worker and face a negligent-referral suit.

What a Former Employer Can Share

Without any paperwork from the employee, a former employer can confirm the basic, verifiable facts of the employment relationship: dates of employment, job title, and the duties the person performed. These answers carry minimal legal risk because they are objective and easy to confirm against payroll and personnel records.

A former employer can also state whether the person is eligible for rehire. That particular statement is specifically protected from defamation claims under California law.¹

If the employee signs a written authorization permitting a more detailed reference, the former employer can go further, but only within the scope the consent document actually spells out. Anything beyond that scope is unauthorized.

Performance-related feedback is permissible when a prospective employer asks for it, provided the comments rest on credible evidence and are made without malice. That last requirement is where most employers get nervous, and it is also what the governing statute is built around.

The Qualified Privilege for Honest References

California Civil Code Section 47(c) shields employers who provide job references from defamation liability. The statute covers any communication about an applicant’s job performance or qualifications made by a current or former employer to someone the employer reasonably believes is a prospective employer, as long as three conditions line up: the prospective employer requested the information, the reference rests on credible evidence, and the communication is made without malice.¹

The privilege disappears in a few situations. Knowingly sharing false information strips the protection. So does volunteering damaging statements nobody asked for. The statute also carves out an explicit exception for speech or activities that are constitutionally protected or covered by other California law, which means a former employer who badmouths someone for union organizing, political activity, or whistleblowing cannot hide behind the privilege.¹

In practice, “without malice” is the phrase that decides most close cases. California courts generally interpret malice here as hatred, ill will, or a willingness to vex the former employee. A harsh reference grounded in documented performance issues will usually hold up. One that embellishes or fabricates problems to sabotage someone will not.

Saying Too Little Can Also Create Liability

Most employers worry about saying too much. California law also creates liability for saying too little in the right wrong way. In Randi W. v. Muroc Joint Unified School District, the California Supreme Court held that an employer who writes a reference letter has a duty not to misrepresent facts if those misrepresentations would create a foreseeable, substantial risk of physical injury to third parties.²

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 information that materially qualified the praise. An employer who voluntarily provides a reference is not required to say everything, but what it does say cannot paint an incomplete picture that conceals a known danger.²

The practical consequence is a real bind. The safest path in many cases is to confirm only basic employment facts and decline to give a substantive reference. If an employer does choose to give a positive reference, it cannot omit serious misconduct that would be relevant to the new role, especially when the job involves vulnerable populations like children, patients, or the elderly.

Topics That Are Off Limits

Salary History

California Labor Code Section 432.3 prohibits any employer from seeking salary history information about a job applicant, whether orally, in writing, or through an agent, and that includes compensation and benefits.³ In reference-check terms, a prospective employer cannot ask the former employer what the applicant earned, and the former employer should not volunteer it.

One narrow exception exists. If the applicant voluntarily and without prompting discloses their own salary history, the prospective employer may consider that information when setting pay.³ The key phrase is “without prompting.” An employer cannot steer the conversation toward salary and then claim the applicant brought it up.

Criminal History

California layers two separate statutes on criminal history, and both affect what belongs in a reference check.

Under Labor Code Section 432.7, employers cannot ask about or use any of the following as a factor in employment decisions:

Arrests that did not result in a conviction, with one exception 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 record related to the juvenile court system, including arrests, adjudications, and dispositions that occurred while the person was a minor.

The ban is not limited to direct questions. The statute bars an employer from seeking the information “from any source whatsoever,” which means a former employer who volunteers it during a reference check puts both itself and the prospective employer at risk.⁴

California’s Fair Chance Act, codified at Government Code Section 12952, adds a timing rule. Employers with five or more employees cannot ask about conviction history on a job application or at any point before making a conditional offer of employment. After a conditional offer, if a background check reveals a conviction and the employer wants to rescind, the employer must complete an individualized assessment weighing the nature and gravity of the offense, the time elapsed since it occurred, and whether the conviction has a direct and adverse relationship to the specific duties of the position.⁵

Medical Information and Protected Characteristics

Federal and state anti-discrimination laws prohibit discussing an applicant’s race, religion, national origin, sexual orientation, age, disability, or any other protected characteristic during a reference check. These traits have nothing to do with job qualifications, and dragging them into a reference can expose both the disclosing and receiving employer to discrimination claims.⁶

Medical information carries its own layer of protection under California’s Confidentiality of Medical Information Act. An employer cannot use or disclose medical information it holds about an employee without a signed authorization, with only narrow exceptions for legal proceedings where the employee’s health is at issue, benefit plan administration, or aiding medical treatment when the employee cannot consent.⁷ Responding to a reference call is not one of those exceptions. Health conditions, disabilities, and workplace accommodations stay out of the conversation.

Anti-Blacklisting Rules

California 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. The statute applies whether the employee was fired or left voluntarily.⁸

Beyond the criminal exposure, an employee harmed by blacklisting can bring a civil lawsuit and recover treble damages without first establishing criminal liability. The former employee does not need a prosecutor to bring charges before filing suit, and whatever damages the court awards are tripled.⁹

The statute also reaches coded references. If a reference letter or statement contains any mark, sign, or other means of conveying information different from what the words themselves express, that fact alone is treated as prima facie evidence of a violation. Internal signals meant to warn other employers off a candidate sit squarely within the statute.

When a Third-Party Agency Is Involved

When an employer handles reference checks in-house by calling a former supervisor directly, federal consumer-reporting laws generally do not apply. The moment an employer hires a third-party agency to investigate a candidate’s background, two overlapping laws kick in: the federal Fair Credit Reporting Act and California’s Investigative Consumer Reporting Agencies Act.

Under the FCRA, before the employer can obtain a consumer report for employment purposes, it must give the applicant a clear, standalone written disclosure and get the applicant’s written authorization.¹⁰ The standalone requirement is strict. Combining the FCRA disclosure with liability waivers or other paperwork can trigger statutory damages.

If the report produces information that leads the employer to consider not hiring the applicant, the employer must follow a two-step adverse action process. First, a pre-adverse action notice goes out with a copy of the report and a summary of the applicant’s rights. The applicant gets a reasonable period to review and dispute. Only then can the employer send a final adverse action notice.¹⁰

California’s ICRAA adds requirements on top of the federal rules. Before obtaining an investigative consumer report for employment purposes, the employer must provide a standalone written disclosure identifying the name, address, and telephone number of the agency, describing the nature and scope of the investigation, and including a summary of the applicant’s rights. The applicant must authorize the report in writing.¹¹ The California disclosure obligations are generally more detailed, so meeting the ICRAA standard will usually satisfy the FCRA. The reverse is not always true.

Penalties for Getting It Wrong

Consequences depend on which statute was broken, and they stack.

A former employee who receives a malicious or unauthorized reference can sue for defamation, invasion of privacy, or employment discrimination under the Fair Employment and Housing Act. Damages in these civil cases are uncapped and depend on the harm shown.
Blacklisting carries a criminal misdemeanor under Labor Code Section 1050, plus civil treble damages under Section 1054.⁸
Salary history violations draw civil penalties of $100 to $10,000 per violation, imposed by the Labor Commissioner based on the totality of the circumstances. Aggrieved applicants can also bring their own civil action for injunctive relief.¹²
Under Labor Code Section 432.7, criminal-history violations draw actual damages or $200 (whichever is greater) for unintentional conduct, and treble damages or $500 (whichever is greater) plus attorney’s fees for intentional conduct. Intentional violations are also a misdemeanor.⁴
Fair Chance Act violations are investigated and enforced by the Civil Rights Department, which can order changes to hiring practices.
Willful FCRA violations carry federal statutory damages from $100 to $1,000 per violation, with class-action exposure for systematic failures.

Document Everything

For an employer giving references, contemporaneous notes about what was asked, who answered, and what was said can be the difference between a defensible reference and a lawsuit. For an employer receiving them, the same discipline applies, especially when a reference or background report surfaces criminal history that leads to a denial under the Fair Chance Act. In that scenario, the employer’s written individualized assessment is often the central document in defending the decision.
