California harassment law requires employers with five or more employees to provide sexual harassment prevention training every two years and implement workplace violence prevention training under SB 553. Employers must also maintain records and provide written policies. Training should meaningfully engage employees, not just meet minimum compliance requirements.
What Is California’s Harassment Training Law
California has some of the most comprehensive workplace protection laws in the United States. Employers operating in the state must now navigate multiple requirements covering sexual harassment prevention training, expanded protections under SB 428, and workplace violence prevention planning under SB 553.
While these laws are designed to protect employees and improve workplace culture, they also place significant responsibilities on employers. Organisations must not only provide legally compliant training but ensure it is genuinely effective and interactive.
This article explains the key elements of California harassment training law and what employers must do to remain compliant while building safer workplaces.
Expanded Harassment Protections Under SB 428
Previously, restraining orders related to workplace safety were typically associated with threats of violence. SB 428 allows employers to seek restraining orders on behalf of employees experiencing serious non-violent harassment.
What Counts as Harassment Under SB 428?
Under the law, harassment may involve behaviour that:
seriously alarms or annoys an employee
lacks a legitimate purpose
causes substantial emotional distress
This expansion allows organisations to intervene earlier before harassment escalates into violence or severe misconduct.
Why the Law Matters for Employers
SB 428 encourages proactive workplace safety. Instead of waiting for behaviour to escalate, employers can act sooner to protect employees.
However, organisations must also balance enforcement carefully. Behaviour protected by laws such as the “National Labor Relations Act (NLRA)” cannot be restricted simply because it causes discomfort.
Employers therefore need clear policies, reporting channels, and well-trained managers capable of recognising problematic behaviour early.
Mandatory Sexual Harassment Prevention Training Requirements
California harassment training law requires all employers with five or more employees to provide sexual harassment prevention training to their California-based staff.
This includes:
full-time employees
part-time employees
seasonal staff
temporary workers
The requirements are enforced by the California Civil Rights Department.
Training Duration Requirements
The law sets minimum training lengths depending on an employee’s role.
Supervisors:
At least 2 hours of training
Non-supervisory employees:
At least 1 hour of training
Training must be interactive, meaning employees must be able to participate through questions, discussions, or scenario-based exercises.
Training Frequency and Deadlines
Sexual harassment training must be repeated every two years.
Additional timelines include:
New hires or newly promoted supervisors
Training must occur within six months
Seasonal or temporary employees
Training must occur within 30 days of hire or 100 hours worked, whichever comes first
The next statewide compliance deadline is January 1, 2027, when all employees must have completed the latest training cycle.
Core Content That Must Be Covered
California requires training to include several specific topics, such as:
legal definitions of sexual harassment under federal and state law
harassment related to protected characteristics including gender identity, gender expression, and sexual orientation
prevention of abusive conduct and workplace bullying
remedies available to victims and reporting procedures
responsibilities of supervisors to report and correct harassment
Training must also provide practical guidance on identifying harassment and responding appropriately.
According to research from the Society for Human Resource Management, harassment training is most effective when it focuses on workplace culture and real behavioural scenarios rather than simply explaining legal rules.
Why Basic Compliance Training Often Falls Short
The California Civil Rights Department has provided free training modules that technically meet compliance requirements.
However, these programmes are often delivered as static online presentations with limited engagement.
While they satisfy legal minimums, many organisations find they do little to influence behaviour or improve workplace culture.
The Limitations of Basic Training
Minimalist training often leads to several challenges:
Employees click through content without engaging
Scenarios feel unrealistic or disconnected from daily work
Managers do not gain practical skills for responding to issues
Sensitive topics such as psychological safety are rarely explored deeply
As a result, employees may complete training but still feel uncertain about how to address harassment in real situations.
What Effective Harassment Training Looks Like
Training that truly works tends to include:
interactive discussions and Q&A sessions
opportunities to practise responding to difficult situations
training tailored to the organisation’s culture and risks
reinforcement beyond the initial training session
Many organisations are now moving toward experiential learning methods that allow employees to explore complex workplace situations in a safe environment.
These approaches help employees understand not only the legal rules but the human impact of workplace behaviour.
Workplace Violence Prevention Requirements Under SB 553
Alongside harassment prevention laws, California introduced a major workplace safety requirement under Senate Bill 553, which came into force on July 1, 2024.
This law requires nearly all employers to implement a Workplace Violence Prevention Plan (WVPP).
The plan must outline how organisations will prevent, respond to, and document workplace violence risks.
What the Workplace Violence Prevention Plan Must Include
A compliant WVPP must be site-specific and accessible to employees at all times.
It must include:
designated individuals responsible for implementing the plan
employee involvement in developing the plan
procedures for identifying and correcting workplace hazards
non-retaliatory reporting processes
emergency response procedures
Hazards may include environmental risks such as poor lighting, isolated work areas, or situations where employees work alone.
Mandatory Annual Training
Employers must provide annual workplace violence prevention training that allows employees to ask questions and engage with the content.
Training must cover:
how to access the company’s prevention plan
how to report incidents without fear of retaliation
workplace-specific safety hazards
strategies for avoiding harm and seeking assistance
Like harassment training, the law emphasises effective and interactive learning rather than passive instruction.
Recordkeeping Requirements
Employers must maintain several records to demonstrate compliance.
These include:
Violent incident logs
retained for five years
Training records
retained for at least one year
Hazard evaluation records
retained for five years
Incident logs must document details of each event while excluding personal identifying information.
Key Exemptions
SB 553 applies to most employers, but there are some exceptions.
These include:
healthcare facilities already covered by industry-specific standards
remote workers operating from locations outside employer control
workplaces with fewer than 10 employees not open to the public
law enforcement and correctional agencies
Even when exemptions apply, many organisations still adopt workplace violence prevention policies as best practice.
How Employers Can Stay Compliant and Create Real Impact
California harassment training law and workplace violence prevention legislation require more than procedural compliance.
To protect employees and reduce risk, organisations should take a proactive approach to training and culture.
Key Strategies for Employers
Prioritise meaningful training
Training should encourage discussion and reflection, not just information delivery.
Strengthen reporting processes
Employees must feel safe reporting concerns without fear of retaliation.
Train managers thoroughly
Supervisors play a critical role in identifying and addressing misconduct early.
Update policies regularly
Policies should reflect evolving risks such as digital harassment and hybrid work environments.
Maintain clear documentation
Training records, incident logs, and hazard assessments are essential for compliance.
Involve employees in prevention efforts
Workplace safety improves when employees participate in identifying risks and solutions.
By integrating these strategies, organisations can move beyond legal compliance and create workplaces where employees genuinely feel safe and respected.
What should you do now?
Organisations that invest in meaningful, engaging learning programmes are far more likely to reduce risk and build healthy workplace cultures.
Ultimately, the goal is not just compliance—but ensuring employees feel protected, supported, and empowered to speak up when issues arise.
