What Is a Hostile Work Environment in California?
A hostile work environment in California is harassment because of a protected characteristic, such as your race, sex, disability, religion, or age, that is severe or pervasive. Severe or pervasive means conduct that alters the conditions of your employment and creates a work environment that is hostile, intimidating, offensive, oppressive, or abusive. One serious incident can be enough. A boss who is harsh with everyone equally usually falls outside this claim, because nothing ties it to a protected characteristic.

At a glance
- The rule comes from the Fair Employment and Housing Act (FEHA), Government Code section 12940(j). The harassment has to be because of a protected characteristic.
- Severe or pervasive is the line, and either one is enough: one bad incident can meet it, and so can smaller incidents that build up. Government Code section 12923 says a single incident can be enough to reach a jury if it unreasonably interfered with your work performance or created an intimidating, hostile, or offensive working environment.
- If a supervisor harasses you while acting in the capacity of supervisor, the employer is strictly liable, meaning it is responsible even if it never knew. For a coworker or a customer, the employer is liable if it knew or should have known and failed to take immediate and appropriate corrective action.
- The harasser can be personally liable too.
- For harassment, FEHA covers employers with one or more employees.
- You generally have three years to file a complaint with the Civil Rights Department (CRD) (formerly DFEH), then one year from its right-to-sue notice to file in court. The federal route through the Equal Employment Opportunity Commission (EEOC) runs on 300 days in California.
What people assume, and what California law says
| What people assume | What California law says |
|---|---|
| Any toxic or badly run workplace is a hostile work environment. | The harassment has to be because of a protected characteristic, such as race, sex, disability, religion, or age, and it has to be severe or pervasive. |
| It only counts if it was aimed at me. | Harassment of coworkers that you personally witness in your immediate work environment can also support a claim. The other elements still apply. |
| I have to prove my work suffered. | You do not have to prove your productivity dropped. It is enough that a reasonable person would find the conduct so altered working conditions as to make it more difficult to do the job. |
| The company is only responsible if HR knew. | For harassment by a supervisor acting in the capacity of supervisor, the employer is responsible whether or not it knew. The knew-or-should-have-known test applies to coworkers and customers. |
| It is just how this industry has always been. | For sexual harassment, the standard does not change by type of workplace, and it is irrelevant that a job has seen more sexual commentary in the past. The nature of the workplace counts only where that kind of conduct is integral to the job duties. |
What is a hostile work environment under California law?
It is a specific kind of harassment claim under FEHA, and it has a definition.
Government Code section 12940(j)(1) makes it unlawful to harass an employee, an applicant, an unpaid intern or volunteer, or a person providing services under a contract, because of a protected characteristic. The same paragraph adds a line people miss: "Loss of tangible job benefits shall not be necessary in order to establish harassment." You do not have to lose a raise, a shift, or your job for the harassment itself to be unlawful.
The name misleads people. A workplace can be tense, badly managed, and miserable, and still be legal. As Jonathan Delshad puts it in the firm's video answer on this question, "A common misunderstanding is that a “hostile work environment” means any toxic or poorly managed workplace. Legally, it doesn’t." If that is closer to your situation, our guide to what a toxic work environment is and when it becomes illegal in California walks through the routes the law does recognize.
What must you prove? The elements a California jury hears
California judges read juries a standard instruction in these cases, CACI No. 2521A (2026 edition). Put in plain English, you must show:
- You were an employee, an applicant, a contractor, an unpaid intern, or a volunteer.
- You were subjected to harassing conduct because of a protected characteristic, or a combination of them.
- The harassing conduct was severe or pervasive.
- A reasonable person in your protected group, in your circumstances, would have found the work environment hostile, intimidating, offensive, oppressive, or abusive.
- You found it that way yourself.
- Either a supervisor did it, or the employer (or its supervisors or agents) knew or should have known and failed to take immediate and appropriate corrective action.
- You were harmed, and the conduct was a substantial factor in causing that harm.
Elements 4 and 5 are two separate tests: an objective one, asking whether a reasonable person in your position would see the workplace that way, and a personal one, asking whether you did. The instruction's own sources quote the California Supreme Court on the second one. A plaintiff "who does not perceive the workplace as hostile or abusive will not prevail, even if it objectively is so."
What does "severe or pervasive" mean?
The jury instruction defines it. Severe or pervasive "means conduct that alters the conditions of employment and creates a work environment that is hostile, intimidating, offensive, oppressive, or abusive."
To decide it, the jury looks at all the circumstances, including:
- The nature of the conduct.
- How often, and over what period of time, the conduct occurred.
- The circumstances under which the conduct occurred.
- Whether the conduct was physically threatening or humiliating.
The test is severe or pervasive, so the conduct can meet it either way. The instruction adds that "A single incident can be sufficiently severe or pervasive to constitute harassment." Comments that would be minor once can add up when they happen every week. Your productivity does not have to decline either. The question is whether a reasonable person subjected to the conduct would find that it so altered working conditions as to make it more difficult to do the job.
Can a single incident create a hostile work environment in California?
Yes, it can. Section 12923(b) says "A single incident of harassing conduct is sufficient to create a triable issue regarding the existence of a hostile work environment if the harassing conduct has unreasonably interfered with the plaintiff’s work performance or created an intimidating, hostile, or offensive working environment."
A triable issue means the question goes to a jury instead of being thrown out by a judge. It does not mean every single comment wins.
The Legislature added section 12923 in 2018 (SB 1300, effective January 1, 2019). In the same subsection, it rejects the federal Ninth Circuit decision in Brooks v. City of San Mateo (2000) by name and says that opinion "shall not be used in determining what kind of conduct is sufficiently severe or pervasive" under FEHA.
What else does Government Code section 12923 say?
Section 12923 is the Legislature's own statement of how courts should read harassment law. Beyond the single-incident rule, these parts of it matter most to an employee:
- The whole picture counts. "The existence of a hostile work environment depends upon the totality of the circumstances".
- Stray remarks can count as evidence. A discriminatory remark, "even if not made directly in the context of an employment decision or uttered by a nondecisionmaker, may be relevant, circumstantial evidence of discrimination." Employers used to argue that one comment from someone outside the decision did not matter. California rejects that "stray remarks doctrine," affirming the California Supreme Court's decision in Reid v. Google, Inc. (2010).
- For sexual harassment, your industry is not an excuse. "The legal standard for sexual harassment should not vary by type of workplace." It is irrelevant that an occupation has seen more sexually related commentary or conduct in the past. The nature of the workplace counts only where that kind of conduct is integral to the job duties.
- A ruling without trial is rarely appropriate. "Harassment cases are rarely appropriate for disposition on summary judgment," meaning a judgment entered by a judge without a trial.
Does the harassment have to be about a protected characteristic?
Yes. Section 12940(j)(1) makes harassment unlawful when it happens because of a protected characteristic.
FEHA protects you against harassment because of race, religious creed, color, national origin, ancestry, physical disability, mental disability, medical condition, genetic information, marital status, sex, gender, gender identity, gender expression, age (40 and over), sexual orientation, reproductive health decisionmaking, and veteran or military status. Harassment because of sex includes gender harassment and harassment based on pregnancy, childbirth, or related medical conditions. The statute adds that "Sexually harassing conduct need not be motivated by sexual desire."
For most of the protected characteristics, including race, sex, age, disability, and sexual orientation, section 12926(o) defines the term to include any combination of them, so harassment aimed at, for example, older women counts even if neither age nor sex alone explains it. The same definition reaches a perception that you have a characteristic, even if you do not, and a perception that you are associated with someone who has one or is perceived to have one. Our explainer on what counts as a protected class in California walks through the full list.
What it does not cover is mistreatment with no connection to any of those. The firm's own answer is direct: "A boss who’s difficult with everyone equally is a different problem, not necessarily a legal one." The useful question is why it is happening to you, and whether it is happening to people who share a characteristic with you.
What counts as a hostile work environment, and what usually does not?
Real cases turn on their facts, so read these as patterns. The forms of harassing conduct come from the jury instruction on "harassing conduct" (CACI No. 2523) and the statute.
| Example | Can it count? | Why |
|---|---|---|
| Slurs, demeaning comments, or "jokes" about your race, religion, or national origin | Yes | Verbal harassment because of a protected characteristic, if severe or pervasive |
| Unwanted touching, or blocking your way at your desk | Yes | Physical harassment, including physical interference with normal work or movement |
| Repeated sexual propositions or remarks about your body | Yes | Unwanted sexual advances are a listed form of harassment |
| Offensive photos, memes, or messages in a work group chat | Yes | Offensive photographs, text messages, and internet postings are examples the jury instruction gives |
| Mocking your pregnancy or treating it as a joke | Yes | Harassment because of sex includes harassment based on pregnancy |
| One physical threat or assault tied to your race or sex | Yes | A single severe incident can be enough |
| Harassment of coworkers that you witness in your immediate work area | It can | A separate jury instruction covers harassment you witness but are not the target of, and it asks more of you |
| A customer or vendor harassing you while your manager shrugs | It can | The employer can be liable for harassment by nonemployees in the workplace if it knew or should have known and failed to take immediate and appropriate corrective action, and its control over them is weighed |
| A boss who yells at everyone equally | Usually not | No connection to a protected characteristic |
| A bad performance review, a reassignment, or being left out of a meeting | Usually not harassment | Ordinary personnel decisions are not harassment, though they can be discrimination or retaliation |
| A single rude comment with nothing more | Usually not | Isolated incidents, unless extremely serious, do not rise to the level of illegality under federal guidance. Under California's section 12923(b), one serious incident can still reach a jury |
The personnel-decision row needs a second look. The California Supreme Court has held that commonly necessary personnel management actions, such as job assignments and performance evaluations, do not come within the meaning of harassment. The same decision can still be discrimination if a protected characteristic drove it, or retaliation if it was taken because you complained. In Roby v. McKesson Corp. (2009), which the jury instructions quote, the same court added that official actions can also communicate a hostile message when they establish a widespread pattern of bias, and that "acts of discrimination can provide evidentiary support for a harassment claim."
If the conduct is sexual and tied to a job benefit, such as a promotion offered for a date, that is quid pro quo harassment, a different claim with its own rules. See quid pro quo harassment examples in California. If you are still sorting out whether your workplace is simply dysfunctional, the signs of a toxic workplace is the better starting point.
Who is responsible: the company, the supervisor, or the coworker?
It depends on who did it.
A supervisor. Section 12940(j)(1) applies its knew-or-should-have-known standard to harassment "by an employee, other than an agent or supervisor," and separately to the acts of nonemployees. The jury instruction's sources quote the California Supreme Court: "an employer is strictly liable for all acts of sexual harassment by a supervisor." Strict liability means you do not have to prove the company knew. There are limits. A later appellate decision quoted in the same instruction says strict liability applies "if the supervisor is acting in the capacity of supervisor when the harassment occurs," and not to a completely private relationship away from work. For sexual harassment by a supervisor, the employer can also argue you could have avoided some or all of the harm by using its complaint procedure. The instruction's sources quote the California Supreme Court that a plaintiff's own conduct "may limit the amount of damages recoverable or bar recovery entirely." The defense goes to damages only. It does not undo the employer's liability.
Who counts as a supervisor. Title does not decide it. Under Government Code section 12926(t), a supervisor is anyone with authority to hire, transfer, suspend, lay off, recall, promote, discharge, assign, reward, or discipline other employees, or the responsibility to direct them or adjust their grievances, or to effectively recommend those actions, using independent judgment. A shift lead who directs your daily work can qualify.
A coworker. Harassment by a coworker is unlawful for the employer "if the entity, or its agents or supervisors, knows or should have known of this conduct and fails to take immediate and appropriate corrective action." This is why a written report matters.
A customer, client, or vendor. For harassment by nonemployees in the workplace, the same knew-or-should-have-known standard applies, and the law weighs "the extent of the employer’s control" over that person.
The harasser personally. Under section 12940(j)(3), an employee "is personally liable for any harassment prohibited by this section that is perpetrated by the employee," whether or not the employer knew.
The employer also has its own duty. Section 12940(k) makes it unlawful for an employer "to fail to take all reasonable steps necessary to prevent discrimination and harassment from occurring."
Employer size. For harassment, size barely matters. FEHA's harassment rule defines employer as "any person regularly employing one or more persons or regularly receiving the services of one or more persons providing services pursuant to a contract". A workplace with two people is covered.
For discrimination, FEHA's general definition "includes any person regularly employing five or more persons". Religious nonprofit employers are handled differently under both definitions.
What should you do if this is happening to you now?
- Write it down as it happens. Date, time, exact words, who else was there. Notes made at the time usually carry more weight than a summary written months later. Our guide to documenting workplace evidence in California covers what to keep, and why secretly recording a conversation is the wrong move in California.
- Keep your own copies. Save your own messages, notes, and photos of anything posted. Do not take confidential company files.
- Report it in writing. An email to HR or a manager creates a record, and it removes the argument that the company never knew. For coworker and customer harassment, that knowledge is part of the test.
- Follow the complaint procedure in the handbook. For supervisor sexual harassment, using the employer's procedure also answers the argument that you could have avoided the harm.
- Watch for retaliation. Firing, demoting, or punishing you because you complained is separately unlawful under section 12940(h). If your shifts, duties, or reviews change after you report, write that down too. See examples of workplace retaliation in California.
- Do not sign a release or severance agreement without review. See what to check before you sign.

How long do I have to file a hostile work environment claim in California?
The CRD complaint: three years. Under Government Code section 12960(e)(5), a FEHA complaint "shall not be filed after the expiration of three years from the date upon which the unlawful practice or refusal to cooperate occurred." Section 12960(e)(6) allows certain extensions. One adds up to 90 days if you first learned the facts of the unlawful practice during the 90 days after the filing deadline expired.
The lawsuit: one year from the right-to-sue notice. To sue under FEHA, you first file with the CRD and receive a right-to-sue notice. Under section 12965, you can then bring a civil action "within one year from the date of that notice." Requesting that notice early has trade-offs, covered in how to sue your employer in California.
The federal route: 300 days. The EEOC's 180-day deadline "is extended to 300 calendar days if a state or local agency enforces a law that prohibits employment discrimination on the same basis," and California has one, the CRD. In harassment cases, the EEOC counts from the last incident, although it looks at earlier incidents too. After a federal right-to-sue notice, you have 90 days to file suit.
Those are the general rules. When the clock started on a run of incidents can itself be disputed. Deadlines can run early, so confirm yours with us instead of assuming you have three years. Tell us what happened.
Frequently asked questions
What qualifies as a hostile work environment in California?
Harassment because of a protected characteristic, such as race, sex, disability, religion, age (40 and over), or sexual orientation, that is severe or pervasive. Severe or pervasive means conduct that alters the conditions of employment and creates a work environment that is hostile, intimidating, offensive, oppressive, or abusive. A reasonable person in your position must see it that way, and so must you.
What is the difference between a hostile work environment and a toxic workplace?
The difference is what you have to prove. A hostile work environment claim under the Fair Employment and Housing Act has elements a jury must find: harassing conduct because of a protected characteristic, severe or pervasive enough to alter the conditions of employment; a reasonable person in your position, and you, found the workplace hostile; and a supervisor did it, or the employer knew or should have known and failed to take immediate and appropriate corrective action. Mistreatment with no protected link does not meet that test, however toxic it feels.
Can one comment create a hostile work environment?
It can. Government Code section 12923(b) says a single incident of harassing conduct is enough to create a triable issue if it unreasonably interfered with your work performance or created an intimidating, hostile, or offensive working environment. One minor rude remark usually will not meet that bar, while a single slur, threat, or assault may be serious enough to reach a jury.
Is my employer responsible if my supervisor harassed me and HR never knew?
Generally, yes. California treats harassment by a supervisor differently from harassment by a coworker: the employer is strictly liable for a supervisor acting in the capacity of supervisor, whether or not it knew. For coworkers and customers, the employer is liable if it knew or should have known and did not take immediate and appropriate corrective action.
What evidence do I need to prove a hostile work environment?
Specific incidents. A general sense that things were bad is hard to prove. Bring dates, exact words, messages, photos, witnesses, and any written complaint you made and the reply. Because the test looks at the totality of the circumstances, a log that shows how often it happened, and who else was treated the same way, is often the most useful thing you can bring.
Do I have to report the harassment to HR before I can sue?
None of the elements a California jury hears under CACI No. 2521A asks whether you first complained to HR. Reporting still helps. For coworker and customer harassment, it shows the employer knew. For supervisor sexual harassment, it answers the argument that you could have avoided the harm. Before a FEHA lawsuit, you do need to file with the Civil Rights Department (CRD) and get a right-to-sue notice.
Can I be fired for reporting a hostile work environment?
It is unlawful to fire you because you reported it. Firing, demoting, or otherwise punishing you because you opposed harassment or filed a complaint is retaliation under Government Code section 12940(h), a separate violation from the harassment itself. If you were fired because you complained, you may have both a harassment claim and a retaliation claim.
When should you talk to a lawyer?
When the conduct connects to who you are, when a supervisor is involved, or when anything changed after you complained. Those facts decide these cases, and the deadlines run on their own. We focus on representing employees. If the harassment is sexual, our Los Angeles sexual harassment lawyer page explains how we handle these matters. Tell us what happened.
