New Jersey Pay Equity Expert Witness

NEW JERSEY PAY EQUITY LITIGATION & COMPLIANCE

New Jersey pay equity: broader comparisons and substantial remedies.

The Diane B. Allen Equal Pay Act covers substantially similar work across protected classes and permits comparisons across an employer’s operations and facilities. It provides a six-year back-pay lookback for qualifying continuous violations and treble monetary damages in specified proceedings. New Jersey also has pay-transparency and state-contractor reporting requirements. Grahall provides statistical analysis and expert-witness support for employers and counsel.

The Diane B. Allen Act, in Practice

New Jersey requires equal pay for substantially similar work, assessed through skill, effort and responsibility, across classes protected by the Law Against Discrimination. Comparisons may draw on all of an employer’s operations and facilities. Permitted differentials include seniority or merit systems, or bona fide factors satisfying the statute’s requirements, including reasonable application, job-relatedness, business necessity and explanation of the entire difference. An available alternative business practice can defeat the business-necessity justification. Employers may not reduce pay to comply.

The six-year back-pay lookback is not the filing deadline. A timely claim may recover up to six years for continuous discrimination; DCR complaints generally must be filed within 180 days and court actions within two years of the most recent discriminatory payment, subject to applicable doctrines. After a jury finds a covered unequal-pay or retaliation violation, the judge must award three times the monetary damages. DCR may award treble damages but is not required to. Trebling is not ordinary damages plus another three times that amount. Other relief may also be available.

Transparency and Reporting

Since June 1, 2025, the posting law generally covers employers with at least 10 employees over 20 calendar weeks that do business, employ people or take applications in New Jersey. Employees outside New Jersey count toward the threshold. Covered postings must disclose pay and a general description of benefits and other compensation; covered employers also must make reasonable efforts to notify employees of promotional opportunities, subject to statutory exceptions. Civil penalties are up to $300 for a first violation and up to $600 for each later violation. Multiple postings for the same opening are not automatically separate violations.

A separate law requires wage and demographic reporting for qualifying-services and public-works contracts with the State or its instrumentalities, not merely every public contract. Qualifying-services reporting covers all employees; public-works reporting covers employees connected to the contract. Contracts with municipalities and counties are excluded from this particular requirement. Local posting rules may impose additional obligations.

Where New Jersey Disputes Are Fought

• Superior Court LAD actions — jury trials, fee shifting, and the treble multiplier make individual claims economically viable and class claims severe.
• Multi-site comparisons — the all-operations rule may broaden relevant comparisons, but it does not itself establish class certification or make every employee an appropriate comparator.
• Agency matters — Division on Civil Rights complaints and Department of Labor posting enforcement.

How Grahall Helps in New Jersey

• Counsel-directed pay equity audits — testing pay across all locations against the substantially-similar standard, with the entire-differential defense in mind, before a posting or complaint exposes it.

  Privilege and work-product protection are not automatic. Counsel should assess the governing jurisdiction, engagement purpose, disclosure duties and possible waiver before work begins or findings are shared. The expert’s analysis and conclusions remain independent.

• Transparency readiness — defensible ranges and benefits descriptions for postings under the 2025 law, scoped correctly for national advertising that reaches New Jersey.
• Public-contract reporting support — the analytics behind gender and race pay data filings, with a pre-submission read of what the numbers signal.
• Litigation support and expert testimony — comparator construction across operations, regression analysis under the entire-differential standard, class certification statistics, six-year and trebled damages quantification, and rebuttal of opposing experts, for either side.

New Jersey Questions We Hear Most

How is treble damages different from other states?

Treble damages means three times the monetary damages, not back pay plus an additional three times back pay. Following a jury finding of a covered unequal-pay or retaliation violation, trebling is mandatory; in DCR proceedings it is discretionary. The recovery period and available additional relief depend on the claim and facts. No separate willfulness finding is specified for this trebling rule.

Our offices pay differently by location — is that a problem here?

It can be. New Jersey permits comparisons across an employer’s operations and facilities. A geographic differential must satisfy the applicable statutory defense; location does not automatically justify it. Legal analysis of job comparability and permitted factors should guide the statistical review.

Does the posting law reach employers outside New Jersey?

It can. Coverage generally requires at least 10 employees over 20 calendar weeks and the specified New Jersey business, employment or application connection. The count includes employees outside the state. Covered national advertisements may be subject to the law, while staffing arrangements and certain promotional notices have exceptions. Map the employer and opportunity to the statutory requirements rather than assuming every advertisement is covered.
