If you are a woman — or any person whose pay is lower than a colleague of a different gender doing the same job — California gives you not one, but two powerful legal shields: the Fair Employment and Housing Act (FEHA) and the California Equal Pay Act (CEPA). Each law approaches the same injustice from a different angle, and together they form one of the most comprehensive frameworks for wage equity in the United States.

Understanding the difference between these two laws is not just an academic exercise. It determines which agency you file with, what evidence you need, what defenses your employer can raise, and what damages you can win. This guide breaks it all down.

The Big Picture: Two Laws, One Goal

The California Equal Pay Act was originally enacted in 1949, making it one of the oldest equal pay laws in the country. In 2015, Governor Brown signed the California Fair Pay Act, which substantially strengthened it — replacing the "equal work" standard with the broader "substantially similar work" standard and eliminating the requirement that compared employees work at the same establishment.^[1]

FEHA, by contrast, is California's sweeping anti-discrimination statute, prohibiting employers from making adverse employment decisions — including compensation decisions — based on sex, gender, gender identity, gender expression, and a host of other protected characteristics. The California Equal Pay Act prohibits only sex-based, race-based, and ethnicity-based pay inequities; FEHA casts a much wider net.^[2]

Then, on October 8, 2025, Governor Newsom signed SB 642 — the Pay Equity Enforcement Act — into law, effective January 1, 2026. It amends CEPA to cover non-binary genders (replacing "opposite sex" with "another sex"), expands the definition of "wages" to include bonuses, stock options, and reimbursements, and extends the statute of limitations to three years.^[3] This is a seismic update for California workers.

What CEPA Requires You to Prove

Under the California Equal Pay Act, you do not need to prove that your employer intended to discriminate. The law applies strict liability: if two employees of different genders are doing substantially similar work — viewed as a composite of skill, effort, and responsibility — and one is paid less, the employer has violated the Act unless it can justify the gap.^[4]

Critically, "substantially similar work" does not mean the same job title. Job titles can be misleading, and the law deliberately looks past them to actual duties. A female "coordinator" and a male "manager" doing the same tasks are protected under CEPA.^[5]

The burden then shifts to the employer to prove the pay difference is based on a legitimate, non-discriminatory factor — such as a seniority system, a merit system, a system that measures production, or a bona fide business necessity. Crucially, these factors must account for the entire wage differential, not just part of it.^[1]

What FEHA Requires You to Prove

FEHA's approach to unequal pay is grounded in anti-discrimination law rather than wage law. Under FEHA, you must show that your employer paid you less because of your sex, gender, gender identity, or gender expression. Unlike CEPA, you do not necessarily need to identify a specific comparator employee who was paid more — you can build a case on circumstantial evidence of bias: performance reviews, promotion patterns, manager comments, and statistical analysis.^[2]

FEHA also provides much broader remedies. Because it is a discrimination law, it allows for emotional distress damages and punitive damages in cases of malicious or oppressive employer conduct — remedies not available under CEPA alone.^[6]

FEHA applies to employers with five or more employees, and covers a far broader set of protected characteristics: race, national origin, religion, disability, age, sexual orientation, gender identity, gender expression, marital status, and more.^[7]

Why Filing Both Claims Often Makes Sense

In many unequal pay cases, it makes sense to bring both an equal pay claim and a discrimination claim. The two laws have different requirements, different defenses, and different damages, and one may succeed where the other faces obstacles.^[2]

For example, if you cannot identify a specific comparator employee paid more than you (a CEPA requirement), FEHA's circumstantial evidence standard may still allow you to prevail. Conversely, if your employer argues there was no discriminatory intent (a FEHA requirement), CEPA's strict liability standard means intent is irrelevant. Bringing both claims creates two independent paths to recovery — and doubles the pressure on your employer to settle.

Both documented and undocumented immigrants are fully protected under both CEPA and FEHA. There is no immigration status requirement to file a wage or discrimination claim in California.^[2]

The Real-World Stakes: Recent Cases

California's equal pay laws are not just words on paper. In 2024, Disney agreed to pay $43.3 million to settle claims that it had underpaid female middle managers for a decade — one of the largest gender pay settlements in entertainment history.^[8] In the same year, Nike faced a class action from four women alleging systemic gender pay discrimination, and Penn State agreed to pay more than $700,000 after similar allegations.^[8]

These cases underscore a simple truth: large employers with sophisticated HR departments still violate these laws — and California employees are winning.

The Bottom Line

If you are being paid less than a colleague of a different gender for doing the same or substantially similar work, California law gives you two powerful legal weapons — and you can use both at once. The California Equal Pay Act does not require you to prove intent. FEHA does not require a comparator. Together, they cover nearly every scenario of gender-based pay discrimination.
