Harassment Prevention Training: What California Employers Must Do

By Ingrid Rainey · June 17, 2025 · 6 min read

California requires harassment prevention training for employers with five or more employees, counting part-time and temporary workers. The requirement is straightforward; the failures usually involve new hires, promoted supervisors, and seasonal staff who slip past the tracking system.

Key takeaways

Training is mandatory at five employees, counting part-time workers and contractors.
Supervisors need two hours every two years; everyone else needs one hour.
Attendance records, not certificates, are what defend the company in litigation.

The baseline requirements

Two hours of training for supervisors and one hour for non-supervisory employees, repeated every two years.
New employees must be trained within six months of hire; newly promoted supervisors within six months of assuming the role.
Seasonal and temporary employees hired for fewer than six months must be trained within 30 calendar days or 100 hours worked, whichever comes first.
Content must cover harassment, discrimination, retaliation, abusive conduct prevention, and harassment based on gender identity, gender expression, and sexual orientation.
Training records — who attended, when, and the materials used — should be retained for at least two years.

Why the record matters more than the certificate

In litigation, training documentation supports an avoidable-consequences defense and rebuts the argument that the employer was indifferent to workplace conduct. Conversely, a supervisor who was never trained, in a company that could not produce attendance records, is an easy story for plaintiff's counsel to tell.

Pair training with a distributed, acknowledged policy, a complaint procedure with more than one reporting channel, and evidence that complaints were actually investigated.

Beyond the minimum

Compliance training satisfies the statute; it rarely changes behavior on its own. Employers that see fewer claims typically add short manager sessions on handling complaints, documenting performance, and avoiding retaliation in the weeks after a report — the period when most retaliation claims are generated.

Building a tracking system that survives an audit

Maintain a single roster showing each employee's hire date, promotion date, training date, and next due date.
Assign one owner — usually HR or the office manager — and calendar a quarterly review of new hires and promotions.
Keep the actual curriculum, slide deck, and vendor certificate for each cycle, not just a completion email.
Capture acknowledgment of the harassment policy at the same time so both records share a date.
For multi-state employers, note that California's requirements exceed most other states' — apply the California standard to anyone working here.

Frequently asked questions

Do remote employees need training?

Yes. Employees working in California must be trained regardless of location, and online interactive training satisfies the requirement.

Does the five-employee count include contractors?

Independent contractors and unpaid interns count toward the threshold for training purposes, so small companies often qualify sooner than they expect.

What if we missed the deadline for a new supervisor?

Train immediately and document it. Late compliance is far better than none, and the gap is otherwise a predictable line of cross-examination.

Who counts as a supervisor?

Anyone with authority to hire, transfer, discipline, assign work, or effectively recommend those actions — job title alone does not decide it, and lead workers often qualify.

Can we use free state-provided training?

Yes. California's Civil Rights Department offers compliant online courses, and using them still requires keeping your own completion records.
