Employment Law
Usually not. California's eavesdropping law makes it a crime to record a confidential conversation without the consent of every party, and a recording made that way is generally not admissible as evidence. There are safer ways to build proof: dated notes, saved messages, written reports and witnesses.

Many employees think a hidden recording is the way to prove what a supervisor said. In California it can backfire. This page explains the rule in Penal Code section 632, the civil exposure that comes with breaking it, and the lawful ways to document harassment. Our employment law page explains the harassment protections themselves.
Penal Code section 632(a) applies to a person who, intentionally and without the consent of all parties to a confidential communication, uses an electronic recording or amplifying device to record or eavesdrop on it. It covers conversations in person and over the phone. The penalties are set out in the statute itself:
| Situation | Possible penalty |
|---|---|
| First violation | A fine of up to $2,500 per violation, up to one year in county jail or a state prison term, or both |
| After a prior conviction under section 632 or certain related sections | A fine of up to $10,000 per violation, up to one year in county jail or a state prison term, or both |
This is a statement of what the law allows, not a prediction of what would happen in any case. The point for employees is simple: a secret recording of a private workplace conversation can create legal problems for the person who made it.
There is a civil side too. Under Penal Code section 637.2(a), a person injured by a violation of this chapter may sue the person who committed it for the greater of $5,000 per violation or three times actual damages, and section 637.2(c) says the injured person does not have to show actual damages. In a workplace dispute, that means a secret recording can hand the employer or the supervisor a claim against you.
| Situation | How the law treats it | Law |
|---|---|---|
| Everyone in the conversation knows you are recording | A person known by all parties to be recording is not treated as an eavesdropper | Pen. Code 632(b) |
| Secretly recording a closed-door meeting with a supervisor | A confidential communication; recording it without everyone's consent is prohibited | Pen. Code 632(a), (c) |
| Remarks at a public gathering or an open public proceeding | Excluded from the definition of a confidential communication | Pen. Code 632(c) |
| Recording a cell phone or cordless phone call | Intentionally recording it without the consent of all parties is a separate offense with the same fine levels | Pen. Code 632.7(a) |
| Recording to gather evidence that the other person is committing extortion, kidnapping, bribery, a violent felony, domestic violence or certain other listed crimes | Not prohibited by the recording sections, and the evidence is not inadmissible in a prosecution for those crimes | Pen. Code 633.5 |
| Using an unlawful recording as evidence | Not admissible in any judicial, administrative, legislative or other proceeding, except in a case about the recording itself | Pen. Code 632(d) |
| Being sued over an unlawful recording | The greater of $5,000 per violation or three times actual damages | Pen. Code 637.2(a) |
Section 632(c) defines a confidential communication as one carried on in circumstances that reasonably indicate that any party wants it confined to the people taking part. It excludes communications in a public gathering, in a legislative, judicial, executive or administrative proceeding open to the public, and in any other circumstance where the parties may reasonably expect to be overheard or recorded.
A one-on-one meeting with a supervisor behind a closed door, or a phone call between two people, is the kind of conversation the statute is aimed at. A remark shouted across a busy, public space may not be confidential, but the line depends on the facts, so it is not a line to test on your own.
Generally no. Under section 632(d), evidence obtained by recording a confidential communication in violation of the section is not admissible in any judicial, administrative, legislative or other proceeding, except as proof in a case about the illegal recording itself. That includes a Civil Rights Department investigation or a court case about harassment. In other words, the recording might not help the claim it was meant to prove.
These are the facts that most often decide whether a recording is lawful and useful.
Under section 632(c), the test is whether the circumstances reasonably show that someone wanted the conversation kept among the participants. A closed office points one way; an open public event points the other. Many workplace conversations fall somewhere in between, which is why advice before recording matters.
Consent is the dividing line. Section 632(b) excludes from the definition of an eavesdropper a person known by all parties to be recording.
Calls involving cell phones or cordless phones fall under section 632.7 as well, which makes intentionally recording them without the consent of all parties a separate offense. A call is not safer to record than a meeting.
Penal Code section 633.5 lets one party record a confidential conversation to obtain evidence reasonably believed to relate to the other party committing extortion, kidnapping, bribery, a felony involving violence against a person, domestic violence or certain other listed crimes. Most workplace harassment complaints do not fit that list, and the section speaks to evidence in a prosecution for those crimes, so it is not a general permission to record a supervisor.
Section 632(b) defines a "person" to include businesses and corporations, not only individuals. The same consent rule that limits an employee's recording also applies to an employer that records confidential conversations.
Your employer's policies may also limit recording at work, so check them before asking to record. A policy cannot, however, require you to stay silent about working conditions: Labor Code section 232.5 bars an employer from requiring employees to refrain from disclosing information about the employer's working conditions, or from disciplining them for doing so, although it does not cover trade secrets or privileged information. If you are later asked to sign an agreement that would keep you quiet about harassment when you leave, our page on whether to sign a severance agreement explains the limits California places on those clauses.
For example, imagine a hypothetical office coordinator at a Glendale dental practice whose supervisor makes sexual comments during their weekly one-on-one meetings, always with the door closed. She considers turning on her phone's voice recorder at the next meeting.
Several rules apply. A closed-door meeting between two people is the kind of conversation section 632(c) treats as confidential, so recording it without the supervisor's consent would violate section 632(a). A recording made that way would generally be inadmissible under section 632(d), and section 637.2 would give the supervisor a possible civil claim against her. Instead, after each meeting she writes dated notes, does not forward work files she is not entitled to have, and emails the practice manager a written complaint describing the comments. She keeps copies of texts the supervisor sent her.
None of this tells her how a claim would end. It tells her how to build a record that can actually be used, without creating a problem for herself.
Not a confidential conversation. Section 632(b) defines a "person" bound by the rule to include businesses and corporations, so an employer needs the consent of all parties to record a confidential communication, just as an employee does.
Yes, if everyone on the call consents. Sections 632 and 632.7 both turn on the consent of all parties, and a person known by all parties to be recording is not treated as an eavesdropper.
Do not share or post it, and get legal advice before using it. A recording made in violation of section 632 is generally not admissible, and section 637.2 allows the person recorded to sue, so the decision deserves care.
An employer may not require you to refrain from disclosing information about its working conditions, or discipline you for doing so, under Labor Code section 232.5. That section does not permit disclosing trade secrets or privileged information.
Notes made at the time, written reports and saved messages are lawful evidence, and the Civil Rights Department lists emails, text messages and screenshots among the documents to bring to an intake interview. A recording is not required to file a complaint.
Retaliation for opposing harassment is unlawful under Government Code section 12940(h). A firing for reporting illegal conduct may also support a claim for wrongful termination in violation of public policy.
