I wasn’t either until a few weeks ago. This small but mighty amendment to California’s Fair Employment and Housing Act (FEHA)was signed into law on October 1, 2025 and goes into effect January 1, 2026. Here’s the gist:

An employee’s assessment, testing, admission, or acknowledgment of their own personal bias that was made in good faith and solicited or required as part of a bias mitigation training does not, by itself, constitute unlawful discrimination.

What could go wrong?

On the surface, SB 303 seems like another example of a law written with good intentions but may not produce the desired results. The language taken directly from the law states the intention to:

(1) Encourage employers to conduct bias mitigation training.

(2) Affirm that conducting a bias mitigation training does not, by itself, constitute unlawful discrimination.

Before I unpack that and the potential consequences of this bill, let’s acknowledge just how hard it is to write good public policy, good laws, or even language that keeps up with the times.

A Brief History of Unconscious Bias

For years, unconscious bias was often offered as professional development rather than compliance training, positioned as a way to grow leaders rather than manage risk. Yet without shared language or clear norms, those sessions could easily drift into risk management. One person’s attempt at honesty landed as another person’s harm. Leaders, wary of stirring things up, kept the work polite and abstract. What looked thoughtful on the surface rarely changed behavior, and in some cases, unstructured conversations did more damage than good by leaving frayed trust and unaddressed impact.

California lawmakers' intention is important as the Fresident has set a precedent of attacking any type of training or program that it views as “unlawful,” “wasteful,” or “discriminatory.” SB 303 seems to be California’s response to allow these critical conversations to continue. Bias mitigation work, when defined well, uncovers and discovers communication barriers that impede productivity. Cognitive biases are the central tenets of corporate work in the information age. Communication, procedural trust, workplace norms, and team dynamics are essential ingredients for every workplace. Social biases of all types are born out of the way our brains process information. Understanding its impact on decisions, communication, and relationships is central for each and every business to prevent bias from becoming institutionalized.

From Safe Harbor to Psychologically Safe Space

SB 303 was written to encourage and promote proactive conversations. Here is the core promise: An employee’s good-faith acknowledgment of their own personal bias, when solicited as part of a bias mitigation training, does not, by itself, constitute unlawful discrimination, i.e.what is said in the context of training cannot be used against the person who said it. 

This legal shift establishes a critical "safe harbor," signaling that awareness and introspection are no longer synonymous with legal liability. On the surface, it clears a path for employees to finally look inward without the fear that their honesty will be weaponized against them.

However, the efficacy of this law hinges on a single, high-stakes distinction: Admission vs. Aggression.

While SB 303 shields the act of uncovering a bias, it is not a permit for prejudice. Understanding the line between these two is essential for every leader and HR professional, particularly when navigating sensitive areas like age-related bias:

This "Unavoidable Moment in the Room" underscores that while the law reframes the value of honesty, it does not excuse the presence of harm. Without a deliberate, expertly facilitated structure, these "honest" moments can easily pivot from breakthrough to breakdown.

Effective bias mitigation training is invaluable precisely because it captures these cognitive shortcuts in a controlled environment. By surfacing these biases into the light of conscious awareness, they can be re-evaluated as faulty data, stripped of their power, and replaced with more intentional, professional decision-making that values experience and innovation equally.

Without a deliberate and structured setting for crucial conversations, unconscious biases will inevitably continue to govern decisions, relationships, and output. Bias mitigation training is invaluable because it provides a chance to be intentional in addressing these biases. This process can bring certain cognitive biases to conscious awareness, where they can be sincerely re-evaluated as shared understanding, identified as untrustworthy information, or eliminated as obstacles to better communication and stronger professional connections.

The truth is, even with SB 303, employers retain a mandatory duty to prevent and correct harassment.

This brings us to the moment that keeps HR directors up at night: when something unscripted, raw, or morally offensive is said during a session. Everyone freezes. People are watching to see what happens next.

SB 303 doesn't make this moment easier—it makes it manageable. If a comment lands and leadership allows it to stand, the risk for the organization increases, not decreases. Silence is not neutrality. Inaction is not safety. The pernicious characteristic of “bias” is not if the discomfort will arise but when. 

The Percipio Company empowers business leaders with the 21st-century skills necessary to navigate Tension and Accountability successfully. Expert facilitation is required to mitigate risk and understand power dynamics, and turn these moments into the growth opportunities.

At Percipio, we operate from a fundamental truth: If you have a brain, you have bias®. Workshops that never get uncomfortable are not doing the work. But discomfort without skill is reckless.

When an offensive statement occurs, our experienced facilitators treat it as a teachable disruption. They are trained to:

  1. Separate the person from the brain’s shortcut.
  2. Name the impact on the room.
  3. Recenter psychological safety on those who were affected.

Awareness and accountability move together. This is the craft of holding tension—the hardest part of the work. Too little tension and people disengage. Too much, and trust erodes. This sweet spot requires presence, experience, and judgment; it cannot be automated. Pre-configured Generative AI may be able to provide individual sounding boards & digital role play but work/life is not a dress rehearsal. Executives, Directors, Managers, and individual contributors all can be upskilled to be Inclusive Leaders.

This is why we don't rely on a single facilitator. Our bench of trusted advisors have spent decades navigating the stickiest moments that arise when bias mitigation is done well. They know when to slow down, when to interrupt, when to press, and when to protect. The Invitation: Treat Bias Mitigation as universal professional development for everyone in your organization. 

SB 303 makes honest conversations possible. It does not make them safe by default.

The organizations that succeed are the ones that treat bias mitigation as a leadership discipline, not a legal workaround. They prepare for the real moments, not just the planned ones. They realize that bias mitigation is not a one-and-done, checkbox measure. It’s part of a strategic plan that extends beyond the scope of a lunch-and-learn or half-day workshop.

If you are ready to do this work with the structure, fluency, and care your organization deserves, best not to do it alone.
