When Employers Use Market Rate Surveys to Justify Wage Gaps

You ask why a teammate at the same level is paid more. HR says the quiet part politely: “The market rate.” A glossy survey appears — a spreadsheet of percentiles, boxes shaded green — and suddenly the conversation ends. In New Jersey, that answer is not the end of the story. 

Under the state’s equal pay laws, market data is not a free pass to pay protected groups less for substantially similar work. Employers must meet strict, fact-based requirements — and many “market” explanations don’t pass legal muster.

Let’s unpack how market surveys are supposed to work, where they fail under New Jersey law, how “substantially similar work” is judged, what a lawful pay difference actually looks like, and when it’s time to talk to an equal pay act lawyer in New Jersey. 

“Market Rate” And How It Affects The New Jersey Wage Gap

In 2023, women working full time earned about 83 cents for every dollar paid to men, slipping slightly from 2022’s narrowest gap on record: 84 cents on the dollar. That national “market rate” still reflects generations of unequal pay patterns that have yet to disappear — but it’s still one of the most common excuses to justify unequal pay.

In pay-setting, “market” often refers to third-party surveys (think compensation vendors, industry salary reports, and benchmarking tools). Companies use those to set ranges and to place people within a range based on experience, performance, and location. That’s fine in theory. But under New Jersey’s equal pay framework, the market cannot be used to legitimize a discriminatory gap. 

If a survey bakes in historical bias — for example, lower pay for women or people of color in a field — then relying on that survey carries the bias forward. New Jersey law explicitly requires more than “the market says so”. 

The federal enforcement community has said the same thing for years. The EEOC has long rejected the “market rate” defense when it perpetuates sex-based or other protected-class differentials. Job content, not external pricing alone, controls — a principle that aligns with New Jersey’s broader standard.

New Jersey’s Legal Framework: Where State And Federal Law Overlap

Two layers matter most in New Jersey:

Diane B. Allen Equal Pay Act

Diane B. Allen Equal Pay Act, an amendment of the New Jersey Law Against Discrimination, It is unlawful to pay a worker who is a member of a protected class less than a comparable worker outside that class for substantially similar work — evaluated as a composite of skill, effort, and responsibility. 

Employers cannot forbid or retaliate against workers who talk about their salaries with co-workers and discuss bonuses or benefits. These conversations often reveal patterns of unequal pay that might otherwise remain hidden. 

If those discussions raise concerns about fairness or compliance, speaking with an NJ-based attorney familiar with the Equal Pay Act can help you understand whether the pay differences violate state or federal law — and what steps to take next to protect your rights.

Federal Law (Equal Pay Act and Title VII)

The EPA requires equal pay for substantially equal work between men and women; Title VII bars pay discrimination across protected categories when tied to discriminatory motive or disparate impact. These federal protections sit alongside New Jersey’s broader, “substantially similar work” standard.

New Jersey’s statute and official guidance make something else very clear: employers bear the burden to justify a pay difference once a worker shows they’re paid less for substantially similar work. Simply pointing to “market data” or engaging in title inflation (for example, giving one employee a slightly grander title to justify higher pay for essentially the same duties) doesn’t meet the legal standard.

When “The Market Rate” Justifies The Wage Gap In New Jersey — And When It Doesn’t

Under the New Jersey Equal Pay Act, wage differences between employees performing substantially similar work are legal only in very limited situations. This applies not only to base salary, but also to unequal bonus pay, incentive programs, and other forms of compensation. Once a disparity is shown, the employer carries the burden of proving that the difference is lawful.

Valid Defenses: Seniority or Merit Systems

The first lawful defense is a seniority or merit system: one that is clearly defined, consistently applied, and genuinely tied to performance or tenure. A vague or informal system will not meet the legal standard.

The Second Option: Five Conditions To Meet

If no valid seniority or merit system exists, the employer must satisfy all five strict requirements to justify the pay gap. They must show that:

1. The pay difference is based on legitimate, bona fide factors such as education, training, experience, or productivity.
2. The factor is not based on or perpetuating bias related to sex or another protected trait.
3. The factor is applied reasonably and consistently.
4. The factor or combination of factors accounts for the entire wage difference.
5. The factor is job-related and based on a legitimate business necessity, and there is no alternative practice that would achieve the same purpose without creating the pay gap.

Missing even one of these requirements defeats the employer’s defense, and the New Jersey Equal Pay Act sets a high legal bar for justifying pay disparities. 

The Garden State recognizes that generic explanations like “the market rate is higher” or “men in this role earn more elsewhere” do not satisfy the Equal Pay Act’s requirements. Employers must provide detailed, factual, and lawful reasons for any pay differences.

If you suspect pay discrimination or unjustified wage gaps, you may have grounds for a legal claim. Speaking with an experienced equal pay act attorney in New Jersey can help you understand what evidence matters most and how to pursue fair compensation safely.

How Market Surveys Often Fail Under New Jersey Law

Here’s where “market” explanations tend to collapse under the state’s test:

• Perpetuating Historical Bias. If a survey reflects inherited industry gaps (for example, women historically paid less for the same role), using it to justify a current difference perpetuates discrimination — which state guidance forbids.
• Not Accounting For The Entire Gap. Many survey defenses explain a portion of the difference (like a location uplift), but not all of it. New Jersey requires that one or more bona fide factors explain the entire differential, not only the part.
• Not Job-Related Or Applied Reasonably. A national benchmark may price an “industry average” that doesn’t match your actual job content and responsibility. If the benchmark ignores your composite of skills and duties, it’s not job-related in the way the law requires.
• “Business Necessity” Without Alternatives. An employer must show that the chosen factor is grounded in legitimate business necessity and that no less discriminatory alternative would meet the same purpose. Many market-based decisions fail this step because alternatives (structured range placement, standardized mid-point rules, or equity adjustments) exist.
• Inconsistent Use Of Data. If the same survey supports higher offers for one group and lower for another — or the company “adjusts” the methodology case-by-case — that inconsistency undercuts the claim that market is a bona fide, reasonably applied factor.

New Jersey law prohibits retaliation because you raised concerns about compensation or asked why pay differs for substantially similar work. If a “market” conversation is followed by write-ups, lost opportunities, or chilled reviews, that’s a separate violation with treble damages exposure in appropriate cases.

What Counts As “Compensation”: Broader Than Base Pay

New Jersey’s Equal Pay Act treats all forms of compensation as part of the equation. That means the law covers not only base salary and overtime, but also bonuses, equity grants, stock options, differentials, benefits, and more.

If an employer equalizes one part of pay — such as base salary — but quietly leaves unequal stock options, bonuses, or benefits in place, they’re still in violation of the law. An employer cannot also lower anyone’s pay to comply; instead, they must raise the lower rate to close the gap.

The Equal Pay Act requires broad comparison across all of an employer’s operations or facilities, not only within your department or location.

How New Jersey’s Salary-History Ban Fits In

The state’s salary-history law bars employers from screening applicants based on prior pay or requiring that prior pay meet a threshold. While employers can still talk ranges and expectations, they can’t legally anchor your pay to your old number. That matters because “market” explanations frequently smuggle in salary history; in New Jersey, that approach is risky at best and unlawful at worst.

Market Data Is A Tool, Not A Defense

Comp surveys can help build fair pay programs. They can also be used to freeze inequity in place. New Jersey law draws the line: if two employees perform substantially similar work, pay should be equal — unless the employer proves a narrow, valid reason that is job-related, explains the entire gap, and doesn’t perpetuate bias. 

“The market says so” isn’t enough. If you’re hearing that line, you’re right to ask more questions.
