The Lilly Ledbetter Rule in NJ Pay Discrimination: Why Every Unequal Paycheck Restarts Your Filing Window

Unequal pay isn’t always obvious. Employees often have little information about what coworkers earn, making the disparities difficult to identify. The Lilly Ledbetter rule recognizes that discrimination can continue over time. 

Many claims come to light long after the original compensation decision was made. Our legal team at Brandon J. Broderick frequently speaks with employees who had no reason to suspect they were being paid unequally. Sometimes a disparity becomes apparent years later through promotion records or changes in the workplace. 

Employers focus on when the decision occurred, while the Lilly Ledbetter rule focuses on the continuing effect of that decision. Each discriminatory paycheck creates a new violation and restarts the filing period for challenging unequal wages.

This article explains how the Lilly Ledbetter rule applies, why each unequal paycheck matters, how courts evaluate continuing compensation disparities, and when to consult an equal pay lawyer in New Jersey.

What the Lilly Ledbetter Rule Means for New Jersey Workers

Many workplace disputes stem from a specific event that an employee immediately recognizes. Pay discrimination is different because decisions occur out of view. Employees may not learn that they are being paid less than a comparable coworker until years later.

Lilly Ledbetter worked for Goodyear Tire & Rubber Co. for nearly two decades. Near the end of her career, she learned she had been paid substantially less than her male counterparts performing similar work. She filed a discrimination claim under Title VII of the Civil Rights Act of 1964. The case eventually reached the U.S. Supreme Court in 2007.

In Ledbetter v. Goodyear Tire & Rubber Co., the Supreme Court held that the filing deadline began when the employer made the original pay decision. Later paychecks reflecting that decision didn’t restart the filing period. Because the original decisions occurred outside the filing period, her claim was barred.

Many lawmakers and legal scholars argued the ruling ignored how compensation discrimination often works. Employees rarely receive notice that a coworker earns more. Some companies discourage salary discussions. Others maintain payroll systems that are difficult for workers to understand.

Congress responded by passing the Lilly Ledbetter Fair Pay Act of 2009. President Barack Obama signed it into law as the first bill of his administration. The law changed how filing deadlines operate. Instead of focusing solely on the original decision, federal law treats each biased check or unequal bonus as a new violation.

These differences tend to build over time. A lower starting salary leads to lower raises, smaller merit increases, reduced retirement contributions, and lower overall compensation. What begins as a single pay decision can affect earnings for years afterward.

Several events trigger a new filing period under federal law. This includes:

• Making a discriminatory decision
• Maintaining a biased compensation practice
• Issuing a check affected by an earlier unfair decision

Federal protections apply through several statutes, including Title VII, the Age Discrimination in Employment Act, and the Americans with Disabilities Act. According to the EEOC, a discriminatory paycheck starts a new filing period. An equal pay attorney in New Jersey can help evaluate filing deadlines and potential claims once the disparity is uncovered. 

How New Jersey Equal Pay Law Treats Filing Deadlines 

In 2018, New Jersey enacted the Diane B. Allen Equal Pay Act, one of the strongest equal pay laws in the country. The legislation amended the New Jersey Law Against Discrimination.

Many discussions focus on sex discrimination. New Jersey's law reaches further. Pay disparities based on protected characteristics covered by the LAD fall within the statute. Protected categories include race, national origin, age, disability, pregnancy, sexual orientation, gender identity, marital status, and several others.

Another important difference involves the comparison standard. Federal claims often involve employees performing substantially equal work. New Jersey uses a broader standard: substantially similar work when viewed as a composite of skill, effort, and responsibility. 

Different job titles do not automatically mean the jobs are truly different. Employers aren’t allowed to assign different labels to comparable positions. Confidential salaries also make disparities harder to spot. Workers have no way of knowing how their compensation compares to others. 

Compensation receives a broad reading as well. Benefits, bonuses, commissions, incentive payments, stock awards, and other forms of remuneration may become part of the comparison.

Under the statute:

• Employers carry the burden of explaining wage differences.
• Legitimate factors must fully account for any wage gap.
• Reducing another employee’s salary doesn’t fix an unlawful disparity. 
• Employees at different locations may still be compared when the same compensation practices apply across the organization.

New Jersey also places limits on employer defenses. A company cannot rely on business judgment alone. Any wage gap must be supported by legitimate factors such as education or seniority. They must relate to the position and account for the difference in wages.

In 2024, women working full-time earned median weekly wages equal to approximately 83% of men's median weekly earnings. National statistics don’t prove bias in any individual workplace, but they illustrate why pay equity remains an active issue across industries. 

Some disparities grow over time rather than staying the same. Annual raises are frequently calculated as a percentage of existing salary. Employees who start at a lower hourly rate will continue falling further behind. In many cases we build at Brandon J. Broderick, the original wage gap is only part of the claim. A compensation difference that appears small during the first year becomes substantial after several years of raises and bonuses. 

How Accrual Pay Works in New Jersey Discrimination Claims

A biased decision rarely affects only a single moment in time. Salary decisions continue influencing future raises or bonuses. When employees keep getting paid under the same structure, the disparity moves forward with each pay period. 

New Jersey’s Equal Pay Act addresses this issue. An unlawful employment practice occurs each time an employee is affected by a discriminatory compensation decision or practice. This approach mirrors the principles behind the federal Lilly Ledbetter Fair Pay Act. 

New Jersey adopted a generous approach to damages. Employees may recover back pay for up to six years preceding the filing of a claim if the violation remained continuous during that period.

Patterns of bias develop over time:

• An employee starts at a lower salary than coworkers performing similar work.
• Bonuses are calculated from existing hourly rates.
• Retirement contributions rise or fall with compensation.
• Promotions and future raises build on current earnings.
• Over time, the difference in compensation grows even though performance remains comparable.

Many employees don’t discover the disparity until years later. Without paycheck accrual rules, some claims would expire before workers ever had an opportunity to learn that the wage gap existed.

Common examples include:

• A female manager starts at a lower salary than male managers performing substantially similar work, and years of raises gradually widen the gap.
• A Black employee receives smaller compensation increases than similarly situated coworkers during multiple review cycles.
• A disabled employee remains in a lower pay range despite performing substantially similar duties to higher-paid colleagues.
• A pregnant employee misses a compensation increase and continues earning less long after returning to work.

In each situation, the effects of the original decision continue showing up in later paychecks and compensation.

Timing helps determine whether a claim is still eligible to proceed. Proving discrimination requires a separate analysis of the facts, compensation practices, and evidence. Throughout our work on equal pay claims, we regularly focus on two different questions: one concerns access to the claim, while the other concerns proving it. 

Continuing Pay Discrimination and Employer Defenses Under New Jersey Law

New Jersey's Equal Pay Act recognizes several legitimate explanations for compensation differences. A defense succeeds only when the factor explains the disparity. Employers must show more than a general preference or unsupported assumption. For example:

• Seniority systems.
• Performance-based merit increases.
• Specialized certifications or credentials.
• Relevant education levels.
• Experience directly related to the position.
• Geographic wage differences are tied to business necessity.
• Shift differentials for overnight or specialty schedules.
• Revenue-generation responsibilities.
• Highly specialized technical skills.

Courts look beyond labels and examine how decisions operate. An employer might point to experience as the reason for a wage gap. But that explanation does not carry much weight when employees have comparable qualifications and perform substantially similar work.

Pay history has become another major focus in many claims. Employers historically used prior salary information when setting wages. This sometimes allowed older disparities to follow employees throughout their careers. A lower salary in one position influenced the decisions in the next.

Transparency has also changed the conversation. Employees have greater access to information today than workers did during Lilly Ledbetter’s employment. Salary disclosure laws, public pay ranges, compensation reporting requirements, and more open workplace discussions about wages have made disparities easier to identify. 

Greater awareness has not eliminated workplace discrimination. The EEOC received 88,531 new charges in 2024. This represents an increase of roughly 9% from the previous year. During the same period, the agency secured nearly $700 million in monetary relief for workers. 

Not all those charges involved bias in compensation. The figures illustrate that discrimination claims remain common across the country.

Why the Lilly Ledbetter Rule Still Matters Today

Pay disparities are often hidden from the employees affected by them. Compensation decisions happen behind closed doors, and workers may learn about unequal pay years later.

When a disparity continues appearing in current wages, benefits, or other compensation, the law treats those continuing effects differently from many other workplace claims.
