You see a job posting and the salary range looks great. You apply, get hired, and then a coworker doing the same work mentions they make more. Maybe a lot more. For years, California workers had some tools to push back on that, but those tools had limits. As of January 1, 2026, a new law called Senate Bill 642 changes the picture in some important ways.
SB 642, called the Pay Equity Enforcement Act, amends two key California laws: Labor Code section 1197.5 (the Equal Pay Act) and Labor Code section 432.3 (the Pay Transparency Law). The changes affect what counts as equal pay, what employers must put in job postings, and how long an employee has to bring a claim. Here is a plain-English breakdown for both employees and employers.
What SB 642 Changes About Equal Pay
California has had an Equal Pay Act on the books since the 1940s. The basic idea is simple. Employers cannot pay employees of one sex less than employees of another sex for doing substantially similar work, unless the difference is based on a real factor like seniority, merit, productivity, or experience. Senate Bill 642 keeps that core rule and updates a few important pieces of Labor Code § 1197.5.
From "Opposite Sex" to "Another Sex"
The old version of section 1197.5 talked about pay disparity between employees of "the opposite sex." Section 1197.5 now reads "another sex." It looks like a small edit, but it matters. The new wording is meant to cover nonbinary employees and people whose gender identity or gender expression does not fit a male-female framework. If two people are doing substantially similar work, the protection applies regardless of where they fall on the gender spectrum.
A Much Broader Definition of "Wages"
Here is one of the biggest practical changes. Section 1197.5 expands what counts as "wages" for purposes of the Equal Pay Act. The amended statute lists, as examples, salary, overtime pay, bonuses, stock, stock options, profit sharing and bonus plans, life insurance, vacation and holiday pay, cleaning or gasoline allowances, hotel accommodations, reimbursement for travel expenses, and other benefits.
Under the older rules, a worker who suspected pay discrimination often had to look only at base pay. The new definition covers a much wider slice of the compensation package. That matters because pay gaps frequently hide in bonuses, equity grants, and perks rather than in the base salary number on an offer letter.
One technical point worth flagging: this expansive definition of wages only applies to section 1197.5. It does not change what counts as wages under other parts of the Labor Code, such as the rules on final paychecks or wage statements.
More Time to Bring a Claim
Section 1197.5 also gives workers more time. Under the older rules, the basic limit on filing an equal pay claim was two years, with three years allowed for a willful violation. The amended statute sets a flat three-year statute of limitations, running from "the last date the cause of action occurs" rather than from the first.
The recovery period also stretches. An employee can recover for the entire time the violation existed, capped at six years. The statute makes clear that a new cause of action arises each time the worker is affected by the pay decision, including each paycheck that reflects the disparity. In practical terms, an ongoing pay gap may keep restarting the clock with each payday.
What SB 642 Changes About Pay Transparency
California's Pay Transparency Law, in Labor Code section 432.3, already required employers with 15 or more employees to include a pay scale in job postings. SB 642 sharpens what "pay scale" actually means.
Under the amended statute, a pay scale is a good faith estimate of the salary or hourly wage range that the employer reasonably expects to pay for the position upon hire. The key phrase is "upon hire." Some employers used to post wide ranges that reflected what the position could pay over a few years of pay raises and promotions. Under § 432.3(m)(1), the posted range is supposed to reflect what the company actually expects to pay a new hire on day one.
If you are a job seeker, that means the number in the posting should be closer to what a real offer looks like, not a far-off ceiling. If you are an employer, it means your job postings need a tighter, defensible range tied to the actual hiring decision, with documentation that supports it.
What This Means for California Employees
If you work in California, the amended §§ 1197.5 and 432.3 may give you stronger tools to address pay disparities. Some practical takeaways:
- Look at the full compensation picture. Equal pay analysis is no longer just about base salary. Stock, bonuses, profit sharing, and even travel-related perks may be relevant when comparing your pay to a coworker doing similar work.
- Pay disparity may not have a single start date. Because each affected paycheck can be its own violation under § 1197.5, an old pay decision that still produces unequal pay today may still be reachable.
- Job postings should reflect real numbers. If you see a California job posting from a covered employer and the range seems unrealistic or absent, you may have rights under section 432.3.
- Nonbinary workers are explicitly covered. The "another sex" language is broad on purpose. It is designed to reach pay gaps that cross gender identity lines, not just male-female comparisons.
- Keep records. Pay stubs, offer letters, equity grant documents, bonus statements, and job postings can all be useful evidence in an equal pay matter.
One thing the amendments do not do is guarantee any particular outcome. Equal pay cases still require evidence that the work is substantially similar, that there is a real disparity, and that the difference is not justified by a legitimate factor like seniority or merit. The new law makes the runway longer and the lens wider, but the basic analysis still applies.
What This Means for California Employers
Employers should treat the amended §§ 1197.5 and 432.3 as a reason to take a fresh look at compensation practices and job postings. Some areas worth reviewing:
- Run a pay equity review. The broader definition of wages means a pay equity audit should look at total compensation, including bonuses, equity, and perks, not just base salary. Many employers do this work under attorney-client privilege.
- Tighten job posting ranges. Postings should show a good faith range the company reasonably expects to pay upon hire. Wide-open ranges that span years of growth may not satisfy the new standard.
- Document the basis for pay decisions. Seniority, merit, productivity, education, and experience can still justify pay differences, but only if the employer can show that the factor was actually applied. Contemporaneous documentation matters.
- Update offer letter and posting templates. Standard templates should reflect the new "another sex" language, the broader wages definition, and the upon-hire pay scale rule. Old templates may quietly create exposure.
- Plan for a longer look-back. With a three-year statute of limitations and a six-year recovery window tied to each affected paycheck, the financial stakes of an unresolved pay gap can grow quickly.
How This Connects to Other 2026 California Pay Laws
SB 642 is part of a wider 2026 push. The state minimum wage moved to $16.90 per hour on January 1, 2026, and SB 464 (Ch. 760, approved October 13, 2025) amended Government Code § 12999, the pay data reporting statute, in three ways worth separating. It requires demographic information gathered by an employer or labor contractor to be stored separately from personnel records. It made the civil penalty for failing to file mandatory rather than discretionary: a court "shall" impose it on the department's request, where the statute previously said "may." And from January 1, 2027 it expands the required job categories from 10 to 23, which first bites on the reports due in May 2027. That last one is the real compliance work and it has a lead time, so an employer that reports pay data should be mapping its workforce to the 23 categories well before then. AB 692 took aim at training repayment and clawback agreements. SB 294 added new rights notice and emergency contact rules. Together, these laws shift more of the compensation and contract conversation into writing and out of informal practice.

How Wiser Workplace Can Help
Pay disputes are often emotional and personal. They can also be hard to talk about across a conference table because the numbers themselves feel private. Mediation gives both sides a confidential space to share the facts, hear each other, and explore a resolution before the dispute becomes a lawsuit.
Wiser Workplace offers a structured, confidential mediation process for California employment disputes, including equal pay and pay transparency issues. Employees can raise concerns without the cost of litigation, and employers can engage early before exposure stacks up under the longer § 1197.5 timelines.
