The California Equal Pay Act (CEPA) is one of the most robust pay equity laws in the nation. It mandates that employers pay employees equally for substantially similar work, regardless of their gender, race, or ethnicity.
If you are being paid less than a colleague of a different background who performs the same essential duties, you may have a legal claim for back pay and liquidated damages.
1. What Is the California Equal Pay Act?
CEPA (Labor Code § 1197.5) bans paying employees less than others of another sex (including non-binary genders), different race, or different ethnicity for substantially similar work.
Substantially similar work is evaluated as a whole based on:
- Skill — required education, training, experience, and ability.
- Effort — physical or mental exertion needed.
- Responsibility — level of accountability and duties.
This must occur under similar working conditions, such as:
- Temperature, ventilation, or air quality.
- Noise, hazards, fumes, or dust exposure.
- Work hours or shift patterns.
- Proximity to (or isolation from) coworkers.
The law covers all forms of compensation (“wages”), including salary, bonuses, overtime, stock options, profit sharing, benefits, vacation/holiday pay, allowances, and reimbursements.
2. When Are Pay Differences Allowed?
Employers can justify pay differences if they prove the gap:
- Is not based on sex, race, or ethnicity.
- Is tied to the job and a legitimate business need.
- Comes from one or more of these factors:
- Seniority system.
- Merit system.
- System measuring earnings by quality or quantity of production.
- Bona fide factors like education, training, or experience.
If a non-discriminatory alternative could achieve the same business goal without the pay gap, the justification fails.
Example: A long-time employee with 20 years of experience might earn more than a new hire doing the same job, even if different genders or races—because seniority and experience are valid.
Employers sometimes misuse these exceptions; if you suspect bias, seek advice.
3. Does Past Salary History Matter?
No—employers generally cannot ask about or rely on your prior salary history to set your pay.
Exceptions:
- Publicly available salary info (via public records laws).
- Your salary expectations (they can ask).
You can voluntarily share past salary info if it helps negotiate a better offer.
Violations (wrongfully asking or using history) can lead to civil penalties of $100–$10,000 per violation.
4. Can You Ask About Pay Information?
Yes—and the law encourages it for transparency.
- Employers with 15+ employees must include a good faith estimate of the salary or hourly wage range in job postings (upon hire expectation).
- After an initial interview, if you reasonably request the pay scale for the role, they must provide it.
- You can ask coworkers about their pay (or discuss your own), and employers cannot retaliate for this.
Transparency helps everyone negotiate fairly and spot disparities.
5. How to Bring a Claim
If you’re paid less due to sex, race, or ethnicity for substantially similar work (or face retaliation), options include:
Option A: File with the California Labor Commissioner (DLSE)
- Simpler, faster, often no-cost.
- Use the EPA-1 form and email to DLSE.
- Your identity stays confidential unless needed for investigation.
- DLSE investigates; if a violation is found, they can demand double back pay + interest, or sue on your behalf.
Option B: File a lawsuit in court
- No need to go through DLSE first.
- Burden-shifting process:
- You show a pay gap for substantially similar work (no need to prove intent).
- Employer proves a lawful reason (e.g., seniority).
- You can then show the reason is a pretext for discrimination.
- Many cases settle via demand letters before court.
If discrimination involves other protected categories (e.g., age, religion), file with the California Civil Rights Department (CRD) instead/under FEHA.
6. Time Limits (Statute of Limitations)
As of 2026 updates (SB 642):
- File a civil claim within 3 years after the last date the violation occurred.
- Each unequal paycheck counts as a new violation.
- You can recover for the full period of violations (up to 6 years max).
Employers must keep wage records for your employment + at least 3 years.
Act quickly—consult an attorney to avoid missing deadlines.
7. What Compensation Can You Recover?
Successful claims often include:
- Unpaid wage difference (back pay).
- Double the unpaid amount (liquidated damages).
- Interest.
- Attorney fees and costs (in lawsuits).
If DLSE finds a violation but the employer refuses to pay, they can sue for you.
8. What If You’re Retaliated Against?
CEPA protects you from adverse actions (e.g., firing, demotion, suspension, reduced hours/pay) for:
- Filing a claim.
- Discussing/asking about wages (yours or coworkers’).
- Helping others with claims.
- Enforcing CEPA rights.
Since 2024 (SB 497), there’s a rebuttable presumption of retaliation if discipline/discharge happens within 90 days of protected activity—the employer must prove it wasn’t retaliatory.
File retaliation claims with DLSE (within 1 year) or sue (within 1 year). Remedies can include back pay, benefits, interest, reinstatement, and more.
Document everything: emails, memos, witnesses.
9. How Does the Fair Pay Act Fit In?
The 2016 California Fair Pay Act strengthened CEPA by:
- Shifting from “equal work” to “substantially similar work” (job titles don’t matter—duties do).
- Allowing statewide comparisons (not just within one site).
This helps ensure fair pay across locations (e.g., rural vs. urban, accounting for cost-of-living differences only if justified).
10. Do Pay Gaps Still Exist?
Yes. Recent data shows women in California earn about 84–87 cents for every dollar men earn (full-time, year-round). The gap is wider for:
- Women of color.
- Mothers.
- LGBTQ+ women.
Largest gaps appear in fields like engineering, law, firefighting, maintenance, and professional services.
Progress continues, but enforcement and transparency are key.
Quick Tips If You Suspect a Violation
- Gather evidence: pay stubs, job descriptions, performance reviews, coworker pay info (if available).
- Don’t sign anything waiving rights without review.
- Contact an employment attorney early—many handle these on contingency.
- Resources: DLSE website (dir.ca.gov/dlse), CRD, or legal aid.
- Contact the Law Offices of Daniel An, PC for a free consultation.
California’s laws are among the strongest for pay equity—knowing them empowers you to demand fair treatment.
