How to Prove Discrimination in the Workplace in California

Getting passed over for a promotion you were clearly qualified for, being terminated shortly after disclosing a pregnancy, or watching a younger colleague get assigned the opportunities you'd been asking for can all feel like discrimination. In California, any one of those situations could cross the line into unlawful treatment, but what creates a viable case is whether the evidence behind it can meet a legal standard.

California's Fair Employment and Housing Act (FEHA) gives workers some of the broadest protections in the country, and employer decisions challenged under FEHA are evaluated under a higher standard than federal law alone would require. Even so, a workable case depends on what you'd need to show, what evidence strengthens or weakens your position, and where the process starts.

Who FEHA Protects and Which Employers It Covers

FEHA makes it illegal for employers with five or more employees to discriminate against job applicants and employees based on protected categories, and harassment based on a protected category is prohibited in all workplaces regardless of size. California protected categories under California law include race, national origin, religion, sex, pregnancy, age (40 and older), disability, sexual orientation, gender identity, marital status, and several others.

Under FEHA, California law covers employers with five or more employees and extends harassment protections to all workplaces regardless of size. FEHA also applies different and less stringent standards for meeting the criteria related to harassment, discrimination, and retaliation than its federal counterparts, which can work in your favor when evaluating whether a specific employment decision is actionable.

The Four Elements You Generally Have to Establish

To succeed on a disparate treatment case at trial, the plaintiff has the initial burden of establishing what California law calls a “prima facie” case. Prima facie translates to “on the face of it”, basically it’s a baseline showing of evidence that is sufficient to support an inference of discrimination. Per California's Civil Jury Instructions (CACI No. 2500), that generally means evidence that the plaintiff was a member of a protected class, was qualified for the position, suffered an adverse employment action, and that circumstances give rise to an inference of unlawful discrimination.

Translated into what that means practically, you'd generally need to show:

• You belong to a protected class under California or federal law
• You were qualified for your position or meeting your employer's legitimate performance expectations
• You experienced an adverse employment action such as a termination, demotion, pay reduction, denial of a promotion, or exclusion from opportunities
• Someone outside your protected class was favored over you, or your treatment was clearly connected to a bias against your protected characteristic

Once an employee presents a prima facie case, the burden is upon the employer to produce evidence of a non-discriminatory reason for the adverse action, at which point the burden transfers back to the employee to show that the employer's stated reason was in fact a pretext for a discriminatory motive (see CACI No. 2570).

Disparate Treatment vs. Disparate Impact

Disparate treatment occurs when an employer intentionally treats someone differently because of a protected characteristic, and disparate impact occurs when a neutral policy disproportionately harms a protected group. Most individual discrimination cases are related to disparate treatment, which requires showing discriminatory intent or motivation.

For example, a workplace policy that requires all employees to pass a physical fitness test could be challenged as disparate impact if it disproportionately screens out workers with certain disabilities, even if the policy makes no reference to disability at all.

Direct vs. Circumstantial Evidence

Direct

Direct evidence of discrimination is uncommon, with employers seldom admitting bias and usually just offering neutral explanations for their decisions. A documented comment from a decision-maker explicitly tying a termination to an employee's age or religion would qualify as direct evidence, and when direct evidence exists, the employee is not required to go through the multi-step burden-shifting analysis at all.

Circumstantial

Most workplace discrimination cases rely on circumstantial evidence showing a record of disparate treatment rather than direct statements admitting bias, and timing, disparate treatment, and pretextual reasoning can establish discrimination even when the employer never explicitly revealed bias.

Circumstantial evidence that may strengthen your case:

• Timing between a protected disclosure and an adverse action — a termination coming shortly after you requested a disability accommodation or announced a pregnancy, for example
• Comparative treatment showing that employees outside your protected class were treated more favorably in similar circumstances, by the same decision-maker
• Statistical evidence showing that employees in a certain age group, race, or gender were disproportionately affected by layoffs or disciplinary decisions
• Changes in how your performance was evaluated after a protected characteristic became known to your employer
• Comments or conduct that reflect bias, even if they weren't part of the formal employment decision

Identifying and Challenging Pretext

Pretext is the legal term for a false or insufficient reason an employer offers to justify an adverse employment decision. Employers in California are sophisticated enough to document performance issues, and a termination framed around attendance or conduct can be hard to challenge if supporting documentation exists on their side and you have none on yours.

Building a Counter-Narrative to the Employer's Stated Reason

A documented history of strong performance (prior reviews, letters of commendation, work output) can directly counter an employer's claim that a termination was performance-based. Under FEHA, it is the employer's honest belief in the stated reasons for a termination, and not the objective truth or falsity of the underlying facts, that is technically at issue — which means showing that the stated reason doesn't withstand scrutiny, or was applied selectively, carries significant weight.

Challenging an Employer's Stated Reason for an Adverse Action

An employee's burden is to prove by competent evidence that the employer's stated justification is mere pretext, in other words, that the reason offered for the adverse action was a coverup for a discriminatory motive. Pretext can be shown by demonstrating that the stated reason is factually false, that it was applied inconsistently against employees in your protected class versus others, or that it is insufficient to explain the adverse action given how the employer has handled comparable situations.

Employers sometimes replace a terminated employee with someone from the same protected class to obscure a discriminatory motive, and in those situations, evidence of how the decision was made, who was in the room, and what was communicated leading up to the termination can close that gap.

Building Your Record Before Any Formal Action

A discrimination case is largely built on documentation that existed before an attorney or an agency ever gets involved. Reconstructed timelines and summaries written from memory are considerably less persuasive to attorneys and fact-finders than records created as events unfolded.

At the Law Offices of Jeremy Pasternak, we've seen how the outcome of a case can depend on records the client kept before they ever called us, and how the absence of those records can create obstacles that are difficult to overcome.

• Emails, text messages, and workplace platform communications reflecting differential treatment or biased comments
• Written accommodation requests and your employer's responses to them
• HR complaints you submitted and any responses you received, or didn't receive
• Performance reviews spanning your employment history, particularly any that shifted after a protected characteristic became known to your employer
• Written warnings or performance improvement plans that appeared in close proximity to a protected disclosure or request
• Contemporaneous notes of conversations, including dates, times, and the names of anyone present
• Your complete personnel file, which California law requires employers to provide to current and former employees upon request

Colleague testimony can add meaningful support to a case, and when witnesses aren't available or willing to come forward, documentary evidence alone, including performance records, communications, and comparisons with similarly situated employees, can be sufficient to establish a viable case.

Filing with the Civil Rights Department Before Pursuing a Lawsuit

Before pursuing a lawsuit under FEHA, you are required to submit an administrative complaint with California's Civil Rights Department (CRD). Per the California Civil Rights Department, you have three years from the date of the discriminatory act to do so.

What Happens After You Submit a Complaint

Once a complaint is submitted, the CRD may request information from your employer, speak with witnesses, and review relevant documents. The CRD may also offer mediation as a path to resolution without further proceedings. If the investigation finds evidence supporting your allegations and the parties don't reach a settlement, the CRD's enforcement division reviews the case for potential litigation, and any remedies recovered go to the complainant.

Requesting a Right-to-Sue Letter

You can also request a right-to-sue letter from the CRD, which allows you to proceed with a private lawsuit rather than waiting on the agency's investigation. An attorney can help you evaluate which path makes the most sense given the specifics of your situation and how quickly you need to act.

The Employer's Advantage in a Discrimination Case

California employers with five or more employees are legally required to maintain employment records, conduct harassment prevention training, and document performance issues — and experienced HR departments use those requirements as a litigation roadmap. When an adverse employment decision is made, the documentation supporting it has frequently been in the works long before the decision itself.

The Asymmetry That Works Against You

Challenging a termination or demotion framed around performance or conduct becomes considerably harder when the employer's file is organized and yours isn't. A failure to report discriminatory treatment internally also gives an employer grounds to argue it had no notice of the problem, which can limit both liability and available remedies.
