Who Harassed You? Start There
| Harasser | Key question | Evidence | Liability focus |
|---|---|---|---|
| Supervisor / agent | Did the person qualify as a supervisor or agent with authority? | Job descriptions, org chart, authority over work, discipline, assignments. | California supervisor harassment can trigger strict employer liability. |
| Coworker | Did management know or should it have known? | Prior complaints, witness reports, open conduct, manager observations. | Notice plus failure to take immediate appropriate corrective action. |
| Customer / client | Did the employer control the setting or relationship and know of the conduct? | Customer complaints, manager communications, scheduling and account records. | Knowledge, control, and corrective options matter. |
| Vendor / contractor | Who controlled access, assignment, and workplace conditions? | Contracts, site rules, complaints, access records. | FEHA can reach nonemployee harassment in the workplace. |
| Owner / executive | Was the harasser effectively the employer or a high-level agent? | Corporate records, title, decision authority, reporting structure. | Direct corporate responsibility may become especially important. |
Five Rules For Connecting Harassment To The Employer
- Supervisor harassment creates strict employer liability under California Supreme Court precedent. An employer is strictly liable under FEHA for sexual harassment committed by a supervisor. State Department of Health Services v. Superior Court
- Coworker harassment uses a notice-and-response standard. Harassment by a nonsupervisory employee is unlawful when the entity knew or should have known and failed to take immediate and appropriate corrective action. Gov. Code section 12940(j)(1)
- Third-party harassment can create employer responsibility. FEHA can hold an employer responsible for nonemployee harassment when knowledge, control, and failure to act are shown. Gov. Code section 12940(j)(1)
- Individual harassers can be personally liable. Government Code section 12940(j)(3) provides personal liability for an employee who perpetrates prohibited harassment. Gov. Code section 12940(j)(3)
- Prevention is itself an employer duty. Employers must take reasonable steps to prevent discrimination and harassment, and California separately requires sexual-harassment prevention measures. Gov. Code section 12940(k); Gov. Code section 12950
Match The Harasser To Notice, Control, And Corrective Action
| Notice | Control | Response |
|---|---|---|
| • Written complaints • Prior complaints by others • Manager observations • Open or notorious conduct • Reports to HR / executives | • Scheduling authority • Site access • Customer/vendor leverage • Assignment authority • Ability to separate parties | • Investigation timing • Interim protection • Discipline or correction • Follow-up with complainant • Retaliation monitoring |
