Harassed by a Customer or Client in California? Your Employer Is Still Responsible

December 09, 2025

Most people assume workplace harassment law only covers misconduct by coworkers and managers. But what if the person making your work environment unbearable is a customer, a client, a vendor, or a contractor — someone your employer does business with but does not directly employ? In California, your employer can still be held legally responsible. The source of the harassment does not eliminate your employer's duty to protect you.

Key principle: California's Fair Employment and Housing Act (FEHA) requires employers to take reasonable steps to prevent and correct harassment in the workplace — including harassment by third parties such as customers, clients, and vendors. An employer who knows about third-party harassment and does nothing can be held liable.

Who Counts as a "Third-Party Harasser"?

Third-party harassment refers to harassing conduct directed at an employee that comes from someone outside the employment relationship. Common examples in California workplaces include:

  • Customers or clients who make sexual comments, send inappropriate messages, or engage in unwanted physical contact with service workers, hotel staff, restaurant employees, or salespeople
  • Vendors, contractors, or delivery personnel who interact regularly with your staff and engage in harassing behavior
  • Clients who make racially derogatory remarks to consultants, lawyers, financial advisors, or other professional service providers
  • Patients who harass nurses, medical assistants, or other healthcare workers — a particularly common and documented issue
  • Guests at events who harass hospitality or event staff

The nature of the job does not change the law. Employees in customer-facing roles are not required to accept harassment as an occupational hazard.

What California Law Requires of Employers

Under FEHA (California Government Code § 12940), employers have an affirmative duty to take all reasonable steps to prevent harassment and to take prompt corrective action when they learn it is occurring. That duty extends to the work environment overall — not just conduct by fellow employees.

When an employer becomes aware that a third party is harassing an employee, the law requires them to:

  • Take the complaint seriously and investigate it promptly
  • Take reasonable steps to stop the harassing conduct — which may include warning the customer, restricting their access, reassigning the employee (with their consent), or terminating the business relationship
  • Ensure the employee is not penalized for reporting — no demotion, no reduced hours, no sudden negative performance reviews
  • Follow up to confirm the harassment has actually stopped

The standard is not perfection — it is reasonableness. An employer who responds promptly and effectively to a customer harassment complaint satisfies their duty. An employer who tells you to "just deal with it" because the customer spends a lot of money does not.

The "Valued Customer" Problem

One of the most common patterns in third-party harassment cases is what employment attorneys informally call the "valued customer" problem: a high-spending client, a major account, or a key vendor is known to harass employees, but management is reluctant to confront them or lose the relationship. Employees are pressured — implicitly or explicitly — to tolerate the behavior to preserve the business relationship.

This is not a legal defense. An employer's financial interest in maintaining a business relationship does not override their legal obligation to protect employees from harassment. Courts and juries are not sympathetic to employers who chose revenue over the safety and dignity of their workers. In fact, documented management awareness combined with deliberate inaction can support a claim for punitive damages.

⚠️ Watch for this retaliation pattern: After you report customer harassment, your employer reassigns you to a less desirable position, reduces your hours, or gives you a negative performance review for being "difficult" with a client. This sequence is textbook retaliation — a separate claim that is often stronger than the underlying harassment claim.

Real-World Scenarios

Scenario A — Retail: A regular customer repeatedly makes sexual comments to a female sales associate. She reports it to her manager. The manager says, "He's a big spender — just avoid him when he comes in." The harassment continues for two more months. The employer's failure to take any corrective action after notice is a FEHA violation.
Scenario B — Healthcare: A home health aide reports that a patient makes racially demeaning remarks during every visit. The staffing agency tells her the patient has the right to choose his caregivers and reassigns her to a less desirable shift with fewer hours. The reassignment is retaliatory; the failure to address the patient's conduct is a failure of the employer's duty under FEHA.
Scenario C — Professional services: An account manager reports to HR that a key client sends her sexually explicit emails. HR tells her to "handle it professionally" and not to jeopardize the account. When she stops responding to the client's messages, she is removed from the account. The employer has both failed to address third-party harassment and retaliated against the employee for reporting it.

Steps to Take If You Are Being Harassed by a Customer or Client

Step 1 — Document every incident

Record the date, time, location, exactly what was said or done, any witnesses present, and how you responded. Screenshot or forward any electronic communications (emails, texts, social media messages) to a personal account immediately. Do not delete anything, even if it is upsetting to keep.

Step 2 — Report in writing to your employer

Report the harassment to your manager or HR in writing — email is ideal — so there is a timestamped record. Be specific: name the harasser (or describe them if you do not know their name), describe what happened, and state clearly that you are reporting this as harassment. "I wanted to follow up in writing regarding the incident on [date] with [customer name/description] to formally report what occurred."

Step 3 — Document your employer's response

Note every response (or non-response) from your employer after you report. Did they investigate? Did they contact the customer? Did they tell you to handle it yourself? The employer's reaction after your report is often the most legally significant part of the story.

Step 4 — Watch for and document retaliation

If your hours are cut, you are reassigned, your performance reviews change, or you are treated differently after reporting, document all of it with dates and specifics. Retaliation after a harassment complaint is independently unlawful under FEHA and the California Labor Code.

Step 5 — File with the California Civil Rights Department (CRD) if your employer does not act

If your employer fails to respond appropriately, file a formal complaint with the CRD at calcivilrights.ca.gov. You have three years from the most recent incident to file. Filing with the CRD is a prerequisite for filing a lawsuit in California court.

Step 6 — Consult a California employment attorney

Third-party harassment cases involve specific legal nuances around employer notice and the adequacy of the employer's response. An experienced California employment attorney can evaluate your documentation and tell you whether you have a viable claim and what it may be worth.

Industries Where Third-Party Harassment Is Most Common

While any employee in a customer-facing role can experience third-party harassment, it is most frequently reported in:

  • Hospitality — hotels, restaurants, bars, event venues
  • Healthcare — hospitals, clinics, home health, dental offices
  • Retail — stores, showrooms, service counters
  • Professional services — law, finance, real estate, consulting
  • Transportation — rideshare, delivery, taxi, transit
  • Education — tutoring, private instruction, after-school programs

California's workforce protections cover employees in all of these sectors equally. The industry does not determine whether the law applies — it only affects the factual context.

Frequently Asked Questions

Can I sue the customer or client directly?

In most cases, your legal claim will be against your employer, not the third-party harasser. Your employer is who owes you a duty under FEHA. In some circumstances — involving physical assault, for example — you may have a separate civil claim against the individual. An attorney can assess both possibilities based on the specific facts.

What if my employer says there is nothing they can do because the harasser is not their employee?

This is a common — and legally incorrect — response. "We cannot control what customers do" is not a defense to an employer's duty under FEHA. What the employer can and should do is warn the customer, restrict access, reassign the employee (with consent), or end the business relationship. The appropriate response depends on the severity and pattern of conduct.

I work in a tip-dependent job. What if I am afraid reporting a harassing customer will cost me tips or shifts?

Fear of economic retaliation is one of the most significant barriers to reporting in customer-facing industries. California law protects you from retaliation by your employer regardless of the impact on individual customer relationships. Your employer cannot reduce your shifts or take other adverse action because you reported harassment. If they do, that is a separate legal violation.

The harassment happened at a client's office, not mine. Does location matter?

No. If you were present at a client's location as part of your job duties, California workplace harassment protections still apply. The relevant question is whether you were in that environment because of your employment — not whether the physical space belongs to your employer.

What if the harassing behavior is subtle — not overtly sexual, but racially demeaning or constantly disrespectful?

FEHA prohibits harassment based on all protected characteristics, including race, national origin, religion, age, disability, and gender — not just sexual harassment. Repeated racially demeaning comments from a customer, for example, can create a hostile work environment that your employer is required to address. Severity and frequency both matter, but a pattern of derogatory conduct does not need to include explicit sexual content to be actionable.

You should not have to choose between your job and your dignity.
