California SB 303 is going into effect on January 1, 2026, altering the legal landscape associated with workplace bias training. Summarising, when an employee self-identifies their own personal bias in good faith at a proper bias mitigation training, the act of self-identification cannot in itself constitute evidence of unlawful discrimination. It’s about eliminating the fear that has prevented many employers from offering such programs in the first place. Let’s get the language of the law, who it affects, and the changes it brings to HR teams across the state, out of the weeds.
Quick Facts
| Category | Details |
| Bill name | California SB 303 |
| Effective date | January 1, 2026 |
| What it amends | The Fair Employment and Housing Act (FEHA) is amended by Government Code § 12940.2. |
| Who it protects | Staff and employers who have completed good-faith bias mitigation training |
| What it does NOT do | Implement training or allow genuine discriminatory actions to be protected from liability. |
| Why it matters | Eliminates the uncertainty that currently makes it difficult for employers to implement bias training |
What Does This Law Actually Say?
SB 303’s essence is that it does two things:
- Promotes employers to provide bias mitigation training
- States that the training itself is not discriminatory to be considered unlawful discrimination
Prior to this legislation, there was a silent (but potent) worry in the HR sector: could an HR employee reveal a bias during a training session (perhaps via a self-assessment or when participating in a workshop conversation), and then have it used against the company in a discrimination claim? However, the answer to that question is found in SB 303. Admission, a test result or acknowledgement of personal bias by an employee as a part of a legitimate bias mitigation program is not sufficient to prove unlawful discrimination.
What Counts as “Bias Mitigation Training” Under the Law?
The statute is rather broad in its definition. It involves any employer-provided training, education or activity that is designed to assist employees in:
- Know about conscious and unconscious thinking.
- Understand the impact of those processes on decisions and behaviour
- Be mindful of ways to minimise personal bias.
This can be done through bias assessments, testing, workshops, toolkits and other continuous bias tracking efforts, but it is important that they are done in good faith and not for the purposes of performative box-checking.
Before vs. After SB 303
| Before SB 303 | After SB 303 (Jan 1, 2026) |
| Employees acknowledge personal bias during training. Employees acknowledge personal bias during training. | Alone, Can cannot provide proof of illegal discrimination |
| The employer conducts bias mitigation training. | Unactionable uncertainty of risk. Uncertainty of risk, which is not legally actionable. |
| Practical discrimination whilst in training | Explicitly protected and encouraged under FEHA |
| Real misconduct not covered by SB 303 | Still actionable |
| This involves the involvement of the employees in training. | Usually reluctant because of legal concerns |
What SB 303 Does NOT Change
It is in this aspect where employers tend to err, so let’s be specific:
- Does not establish a new training requirement. Employers aren’t required to run bias mitigation programs because of this law.
- It does not cover the actual behaviour of discrimination. When harassment, discrimination or retaliation happens during a training session—even if it’s just an acknowledgement of personal bias—the behaviour is still considered to be within the scope of FEHA and other civil anti-discrimination laws and is fully actionable.
- Not emergency contacts, arrests or unrelated HR activities. SB 303 is limited to liability for bias training — nothing more.
Why This Matters for California Employers
This law takes one of the biggest hurdles out of the way for HR teams to hold meaningful bias training: legal liability for participating honestly. Employers can now create training programs that actually promote self-reflection, whether that’s taking a bias assessment, engaging in candid workshop discussions, or providing a bias toolkit, because a worker’s honest admission will no longer be a burden in a lawsuit.
However, employers should proceed with all necessary training on harassment and discrimination as normal. California SB 303 strengthens compliance requirements by placing a protective layer over the existing bias mitigation requirements.
Key Takeaways
- California SB 303 becomes effective January 1, 2026 and adds new legislation to FEHA in Government Code § 12940.2.
- It covers an employee’s good-faith disclosure of personal bias while conducting the training for the purpose of mitigating bias.
- That does not require new training nor cover real acts of discrimination
- The law aims to incentivise increased and more open and honest bias mitigation efforts in California workplaces.
- HR teams should continue to have all other harassment and discrimination training in place, and any bias-mitigating training.
