California employers know that employment law compliance obligations don’t slow down — every year, employers have new laws and regulations that they need to take into consideration as part of their business operations. One of the most significant recent developments was California’s general industry workplace violence prevention requirements, which began on July 1, 2024.
Up until then, many employers had workplace violence policies and procedures in place, but these were optional and varied in scope and depth. The new law made workplace violence prevention programs mandatory for most employers — regardless of size — and established significant compliance requirements, including:
Now, employers must continuously respond to workplace violence concerns, hazards and incidents, conduct periodic inspections, and update their plan and provide additional training as necessary.
Plus, every year, employers must review their workplace violence prevention plan’s effectiveness and provide annual training on the law’s requirements and their plan. Since July 1 will be here soon — the first anniversary of workplace violence prevention plan requirements — employers should begin preparing for these annual requirements, including revising their plans, if necessary.
Workplace Violence Prevention Plan Review
California law requires employers to maintain a detailed workplace violence prevention plan, which may be maintained as a standalone document or integrated into their Injury and Illness Prevention Program (IIPP). Employers must review the effectiveness of their plan periodically — at least annually. But employers must also review their plan when they discover a plan deficiency and after a workplace violence incident.
As a reminder, a workplace violence prevention plan must cover a lot of topics, including:
When reviewing their plans, employers should review all the procedures related to the topics above to determine whether they have been effective. For example, for communication procedures, employers should determine whether:
Employers should also review any procedures that didn’t get used in real-life circumstances to determine if they would still be effective when needed. For example, assuming an employer didn’t have a workplace violence incident all year, they should still review their required post-incident response and investigation procedures to determine if they would still be effective for a workplace violence incident.
Additionally, the workplace violence prevention law specifies that reviewing a plan’s effectiveness includes obtaining the active involvement of employees and authorized representatives. So, employers should involve their employees in the process using effective methods, including for example, obtaining information from employees and their supervisors on how the plan’s procedures have worked over the past year — either in writing, through a form or electronic method, or oral feedback.
During this process, employers should try to be specific. If, for example, an employer is reviewing their plan’s communication processes, they should try to get information specifically about the employees’ experience with those procedures and identify instances in which employees didn’t receive or understand communications or couldn’t report workplace violence concerns or hazards effectively.
Employers should also consider conducting a hazard inspection, as they did when they first established their plan. This may help to identify new or additional workplace violence hazards resulting from workplace changes since the last inspection, which may include, for example, personnel changes, changes in business hours and shift times, or worksite construction or renovations that impact existing workplace safety procedures.
Annual Workplace Violence Prevention Training
Employers must train their employees at least annually on California’s workplace violence prevention law and their specific workplace violence prevention plan. Employers should conduct their annual training after reviewing their plan as described above and making any necessary adjustments for ineffective procedures and/or discovery of new or additional hazards.
Training materials must be appropriate in content and vocabulary, accounting for your workforce's educational level, literacy and language. The training must include materials on:
Generally, the law allows employers that discover a new or previously unrecognized hazard to make changes to their plan and provide additional training that is limited to the new hazard and plan changes. However, employers must provide training annually on all the requirements listed above. So even if an employer reviews their plan and only makes a small revision and trains as to that revision, they must still provide comprehensive training on their entire plan to satisfy annual training requirements.
Remember, employers must maintain employee training records for one year.

Additionally, Cal/OSHA maintains a workplace violence prevention resources page with frequently asked questions about the law, fact sheets and other educational materials. Cal/OSHA is also developing a workplace violence prevention regulation, though it will be some time before a final regulation takes effect. Cal/OSHA has until December 31, 2025, to propose a rule, and the Occupational Safety and Health Standards Board has until the end of 2026 to adopt the rule.
