You suspect you're being paid less than a coworker doing the same job. Maybe someone mentioned a number in passing. Maybe you saw a job posting with a pay range that's higher than your current salary. Maybe you've just had the feeling for a while that something isn't right.
Most employees stop there — suspicion without evidence is hard to act on. But California law gives you more tools than you probably realize. You can check your employer's own pay data, pull pay scales from public job postings, and build a documented file before you ever make a formal complaint. This guide walks through how to do all of it.
Section 1: Your Legal Rights as a Starting Point
Before you start gathering evidence, it helps to know what rights you already have. Three California laws create the foundation for a pay equity audit.
The right to see pay scales (SB 1162)
Since January 1, 2023, any California employer with 15 or more employees must include a pay scale — a salary range — in every job posting. That includes postings on LinkedIn, Indeed, Glassdoor, ZipRecruiter, and the company's own careers page.
This is one of the most powerful tools available to employees. You don't need to ask HR. You don't need a lawyer. You just search.
How to use this:
- Go to your employer's careers page and search for your job title or similar titles.
- Search LinkedIn Jobs, Indeed, or other job boards for your employer's name plus your role.
- Screenshot and save every posting you find, with the date visible.
- If the posted pay range is higher than your current salary — especially for a role you're already doing — that's a data point.
- Repeat the search for similar employers in your industry. If competitors are paying 15–25% more for the same job, that's additional context.
Employers who fail to include pay scales can be fined. But the bigger point for employees is that you can use these postings as benchmarks right now, for free.
The right to discuss your pay (Lab. Code §§232, 232.5)
California law prohibits employers from stopping employees from discussing wages with coworkers. You cannot be fired, disciplined, or threatened for asking a coworker what they make or sharing your own salary (Lab. Code §232). This protection also covers other conditions of employment like hours and benefits (§232.5).
This is how many employees first discover a pay gap. A casual conversation. A question over lunch.
How to do this without creating drama:
- Share your own information first. "I just got my review. They offered me X — does that seem right to you?"
- You don't need to push anyone to disclose. Even knowing that someone is "paid more" without a number is useful for a complaint.
- Keep notes of what you learn, even informal ones. Date, who, what was said.
Your employer's employee handbook cannot legally prohibit these conversations. If your employer punishes you for discussing wages, that's a separate violation.
The salary history prohibition (AB 168)
California employers cannot ask for your prior salary during the hiring process (Lab. Code §432.3). More importantly, they cannot use your prior salary as the sole justification for paying you less than a coworker.
If you were hired at a lower salary based on your previous employer's pay — and your salary has never been corrected — you may have a live violation. This is especially common when someone moves from a lower-paying industry or region, or when women are hired into male-dominated fields.
Ask yourself:
- Did anyone ask about your prior salary during hiring, or was it on an application?
- Was your starting offer based on "what you were making before"?
- Have you stayed at or near that starting salary while coworkers have seen larger increases?
If the answer is yes to these, that pattern matters.
Section 2: How to Use the CRD Pay Data Reports
This is the step almost no guide covers — and it's the single most powerful public tool available to California employees.
Since 2021, California employers with 100 or more employees have been required to file annual pay data reports with the California Civil Rights Department (CRD). These reports break down the employer's median pay by:
- Sex (male, female, non-binary)
- Race/ethnicity (10 categories)
- Job category (10 EEO-1 categories like "professionals," "sales workers," "operatives")
The reports are public and searchable.
How to search the CRD database:
- Go to https://calcivilrights.ca.gov/paydatareporting/
- Click on "Pay Data Reports" or "Employer Search" — the database is available there.
- Search for your employer by name.
- Download or view the report. Look at the median pay columns for your job category (EEO-1 category).
What to look for:
- Find the EEO-1 job category that matches your role. "Professionals" covers most white-collar roles. "Operatives" covers production and assembly. "Sales workers" is self-explanatory.
- Compare the median pay for men vs. women (or by race/ethnicity) in your category.
- If the median for your demographic group is meaningfully lower than for others doing the same category of work, that's a documented gap — reported by your employer, to the government.
- Compare that median to your actual salary. If you're earning below the median for your group, you're on the low end of your employer's own reported data.
The reports don't show individual names or salaries. But they show systemic patterns. If your employer's own CRD filing shows women in your job category earn 18% less than men, that's evidence you didn't have to gather yourself.
Screenshot the report. Save it. Note the filing year.
Section 3: The "Substantially Similar Work" Standard — What Counts as a Valid Comparison
Many employees assume they can only compare themselves to someone with the exact same job title in the same department. That's wrong.
California's Equal Pay Act (Lab. Code §1197.5) uses the "substantially similar work" standard. The comparison is based on three factors:
- Skill — the knowledge, ability, and training required to do the job
- Effort — the physical or mental exertion required
- Responsibility — the degree of accountability and decision-making involved
If two people are doing work that requires the same level of skill, effort, and responsibility, they should be paid the same regardless of their job titles, departments, or even locations within the same company.
Examples of valid comparisons:
- A female project manager in marketing and a male project manager in engineering — same scope, same headcount managed, same budget authority. Different titles, same work.
- A female warehouse team lead and a male warehouse supervisor — both directing a crew of 8, both responsible for shift output, both doing physical loading work. One has "supervisor" in the title. That alone doesn't justify a pay gap.
- A male customer service manager and a female operations coordinator — if both are managing the same number of direct reports, handling similar complexity, and using the same systems, the title difference doesn't matter.
What you don't need:
- You don't need to know the exact salary of the person you're comparing yourself to. The complaint process triggers an investigation that can compel records.
- You don't need someone in the same department, building, or even city (as long as they work for the same employer).
What the employer can claim in defense:
The law allows four justifications for pay differences: seniority, a documented merit system, a production-based pay system, or a "bona fide factor other than sex" (such as education, training, or experience). Critically, the entire pay differential must be justified — not just a portion. If your employer's justification explains a 5% difference and the actual gap is 18%, they're still in violation for the remaining 13%.
Section 4: Building Your Pay Equity File
Before you send a demand letter or file a complaint, you want documentation. This is your pay equity file. You're assembling the evidence; someone else does the investigation.
What to gather:
- Your current job title, salary, hire date, and most recent performance reviews
- Any salary adjustment history (raises given, and when — or raises skipped)
- Your original offer letter and any email from the hiring process discussing salary
- Pay scales from your employer's current job postings (screenshot + URL + date)
- Pay scales from 2–3 competitor employers in the same industry (for benchmarking)
- Your employer's CRD pay data report — downloaded from calcivilrights.ca.gov
- Names, titles, departments, and general job descriptions of coworkers doing substantially similar work (you don't need their salaries — just enough to identify them as comparators)
- Any conversations about wages with coworkers (notes: date, what was discussed, general information only — you don't need exact numbers)
- Any HR communications about pay, raises, or pay band structure
- Any salary history form or application question that asked for prior pay
What you're building: A documented picture showing (1) what you earn, (2) what the posted market rate is, (3) what your employer's own CRD data shows about pay gaps, and (4) who else is doing similar work. That's enough to support either a formal demand or a CRD complaint.
You don't need a smoking gun. You need a documented pattern.
Ready to Put It in Writing?
Once your pay equity file is complete, a written demand to your employer is the first formal step. A demand letter documents the gap, puts the employer on notice, and creates a record before any government complaint is filed.

Section 5: What to Do When You Find a Gap
You've gathered your file. You've compared your salary to the pay scale, the CRD data, and what you know about coworkers. The gap is real. What now?
Step 1: Internal demand letter
A demand letter to your employer is the first move. It puts them on formal notice that you believe a pay violation exists, states the basis for that belief, and asks for correction by a specific date.
This matters for several reasons:
- It creates a written record before any government complaint.
- It gives the employer a chance to correct the problem without a formal investigation.
- If the employer ignores it or retaliates, that response (or non-response) becomes evidence.
The letter should state: your current salary, the comparable role or pay scale, the approximate gap, the legal basis (Lab. Code §1197.5 and/or FEHA §12940), and a deadline for response (typically 30 days).
The Demand Letter Packet ($109.65) is the right document for this step.
Step 2: If the employer doesn't respond or denies the adjustment
If the employer denies the pay adjustment, ignores the letter, or retaliates — your next move is a formal complaint with the California Civil Rights Department (CRD).
How to file a CRD complaint:
- Go to calcivilrights.ca.gov and file online.
- The CRD will open an investigation and can compel your employer to produce pay records.
- You will be asked to describe the basis for the complaint — your pay equity file is your preparation for this.
- CRD can pursue remedies including back pay, interest, and penalty damages on your behalf.
The Civil Rights Complaint Packet ($143.65) helps you organize and prepare your complaint documentation for CRD submission.
Step 3: Civil lawsuit (if CRD doesn't resolve it)
California's Equal Pay Act allows a private right of action directly in Superior Court — no CRD exhaustion required. If you sue and win, you can recover:
- The wage differential (back pay for the period you were underpaid)
- An equal amount as liquidated damages (automatic double recovery)
- Interest
- Attorney fees and costs
FEHA gender discrimination claims also support a civil lawsuit after receiving a right-to-sue notice from CRD.
Section 6: The Deadlines You Can't Miss
Pay equity law has two different deadlines depending on which legal theory you're using. Mixing them up is a costly mistake.
Equal Pay Act deadline: 2 years
Under Lab. Code §1197.5(h), you must file an Equal Pay Act claim within 2 years of the violation. This applies to a direct Equal Pay Act claim — either through a CRD complaint or a private lawsuit.
The good news: each underpayment paycheck is a new violation. The continuing violation doctrine means the 2-year window resets with each paycheck. But the lookback period for damages is still limited to 2 years — you can't recover underpayments from 5 years ago just because the violation is ongoing.
Practical rule: If you think you've been underpaid for 3 years, you can only recover 2 years of back pay under the Equal Pay Act.
FEHA gender discrimination deadline: 3 years
A FEHA sex/gender discrimination claim — filed through the CRD as a discrimination complaint rather than an Equal Pay Act complaint — has a 3-year deadline (Gov. Code §12960).
Many equal pay situations qualify under both the Equal Pay Act and FEHA. The practical difference: FEHA's 3-year window gives you one more year if the Equal Pay Act clock has run out. FEHA also opens the door to additional remedies including emotional distress damages and punitive damages in some cases.
The key distinction
| Claim | Deadline | Path |
|---|---|---|
| Equal Pay Act (Lab. Code §1197.5) | 2 years | CRD or direct lawsuit |
| FEHA gender discrimination (Gov. Code §12940) | 3 years | CRD complaint first; then right-to-sue |
If you're close to the 2-year mark on the Equal Pay Act, don't wait. Each paycheck starts a new clock, but the lookback window for what you can recover is finite.
Taking the Next Step
A pay equity audit isn't complicated when you know what to look for. California law has built-in tools — public CRD reports, mandatory pay scales in job postings, wage discussion protections — that most employees don't use because nobody told them they exist.
If your audit shows a real gap, the next step is a written demand for correction. That puts your employer on notice and creates the record you need before any government complaint.
