An equal pay claim starts with a comparator — a specific person of the opposite sex doing substantially equal work who is paid more. Two federal routes exist and their timing differs sharply: the Equal Pay Act allows you to go straight to court within two years, or three where the violation is willful, while a Title VII claim requires an EEOC charge first, generally within 180 days and 300 in some states. Each discriminatory paycheck restarts the clock, which is the provision that saves most claims.
Start with the comparator, not with the feeling
An equal pay claim is a comparison rather than an assertion, so the first question is not whether your pay feels wrong but who specifically you are comparing yourself to. You need a named person of the opposite sex, at the same establishment or within whatever range your state allows, doing work that is substantially equal in skill, effort and responsibility.
That requirement disappoints people and it is worth understanding rather than resenting. Without a comparator there is nothing for an employer to justify, and the whole burden-shifting structure that makes these claims viable never engages. A general sense of being underpaid is a market question with a market answer, and it is a different question from this one entirely. Both are worth answering, and confusing them wastes months, because the evidence that settles one does nothing for the other.
So the honest first step is to work out whether you have a comparator at all. If you do, you have the beginnings of something specific. If you do not, the useful route may be a benchmarking conversation rather than a legal one, and that is not a lesser outcome — it is frequently the faster way to more money. Benchmarking data is available today, requires nobody’s permission, and produces a conversation about a raise rather than a dispute about a violation.
Document both jobs
Because the comparison is the claim, documenting only your own role does half the work. Keep contemporaneous notes on what you actually do — recurring responsibilities, decisions you make without approval, who you supervise, what happens if you get something wrong — and gather what you legitimately can about the comparator’s role from ordinary sources like the posting it was advertised under or the organizational chart. Those sources are ordinary, publicly visible inside most organizations, and carry none of the risk attached to going looking somewhere you should not be.
Contemporaneous is the word carrying the weight. A dated record made as you go is worth considerably more than a reconstruction assembled once a dispute has started, and it takes a few minutes a week. Keep it somewhere that belongs to you rather than on a company system you might lose access to at exactly the moment you need it. People who leave a job abruptly frequently lose everything stored on a company laptop or account within the hour, and that is precisely when the record matters most.
Be careful about how information is obtained. Discussing pay with colleagues is protected for most private-sector employees and is a perfectly ordinary source. Accessing payroll systems you have no business in is a different act with its own consequences, and it can undermine a claim that would otherwise have been strong.
Two routes, two clocks
The Equal Pay Act route lets you file directly in court without going to an agency first, and the limitation period is two years from the violation, extended to three where the violation is found to be willful. That directness is its main advantage, and it is why the EPA route is often the faster one in practice. It also means the decision to file is yours alone rather than depending on an agency’s assessment of your charge.
The Title VII route runs through the Equal Employment Opportunity Commission and requires a charge to be filed before any court claim. The deadline is generally 180 days, extended to 300 in states with their own fair employment agency, and it is much shorter than most people assume. Somebody who spends three months hoping a situation resolves itself has spent most of a 180-day window without realizing there was one.
The provision that rescues a great many claims is that each discriminatory paycheck restarts the clock. A pay difference set years ago is not time-barred simply because the original decision was old, because every subsequent paycheck carrying that difference is treated as a fresh violation. That is the single most useful thing to know here, and it is why a long-standing difference is still worth raising.
State law adds further routes with their own deadlines, and several state periods are longer than the federal ones. Where more than one route is available, they are not mutually exclusive, and which combination fits depends on facts specific to you. That is one of the main things an early conversation with an adviser settles, and it is settled in minutes rather than hours.
Raise it internally first, in writing
Most of these situations resolve without any legal process, and starting there costs nothing while preserving every other option. Nothing about raising a question internally forecloses a claim later, and a great many pay differences turn out to be errors nobody had examined. A short factual message asking how pay was set for your role, and how it compares to the range for the position, is an ordinary request that a well-run employer answers directly.
Keep it about the role rather than about the comparator at this stage. “I’d like to understand how my pay was set relative to the band for this position” opens a conversation; naming a colleague and a figure opens a dispute, and you can always escalate later while you cannot easily de-escalate. Once a colleague’s name and salary are in an email, the conversation has a different character for everybody in it, permanently.
Put it in writing even if you also raise it verbally. That fixes the date you raised it, which matters for retaliation purposes, and it gives whoever handles it something concrete to act on rather than a recollection of a corridor conversation. It also means that if the person you spoke to leaves, the request survives them.
Retaliation
Retaliation for raising a pay complaint is unlawful under both the Equal Pay Act and Title VII, and the protection covers internal complaints as well as agency filings. It also generally covers participating in somebody else’s claim, which matters where several people are affected by the same practice. Pay differences of this kind are rarely individual, so the person who raises it first is frequently not the only person affected.
A retaliation claim is separate from the underlying pay claim and carries its own deadline, often a shorter one. So note the date you raised the issue and note anything that changes afterwards — hours, assignments, a sudden performance conversation, exclusion from something you were previously part of. That record converts an impression into something anybody can evaluate.
When to get advice
Get advice early rather than when you have decided to act, because the deadlines are the thing that most often decides the outcome and they run whether or not you have made up your mind. An initial conversation with an employment lawyer is frequently free, and many state agencies will discuss a question without any obligation to file anything.
Bring three things to that conversation: your own contemporaneous record, what you know about the comparator’s role and how you know it, and the dates — when the difference began, when you learned of it, when you raised it. Those three are what any adviser needs first, and having them ready turns a vague conversation into a useful one.
This is general information about how these routes work rather than legal advice about your situation. Which route fits, which deadline applies and whether two jobs are substantially equal all turn on specific facts, and the cost of asking early is nothing while the cost of asking late can be the entire claim.
Common questions
What does an equal pay claim need to start?
A comparator — a named person of the opposite sex, at the same establishment or within whatever range your state allows, doing work substantially equal in skill, effort and responsibility.
What if I have no comparator?
Then the burden-shifting structure never engages and there is nothing for an employer to justify. A benchmarking conversation may be the faster route to more money, which is not a lesser outcome.
How long do I have under the Equal Pay Act?
Two years from the violation, or three where it is found to be willful. You can file directly in court without going to an agency first.
How long under Title VII?
Generally 180 days, extended to 300 in states with their own fair employment agency — and a charge must be filed with the EEOC before any court claim.
Is an old pay difference time-barred?
Generally not. Each discriminatory paycheck restarts the clock, so a difference set years ago is still actionable because every subsequent paycheck carrying it is treated as a fresh violation.
Should I raise it internally first?
Usually yes. Keep it about the role rather than naming a colleague — that opens a conversation rather than a dispute, and you can escalate later but cannot easily de-escalate.
Am I protected from retaliation?
Yes, under both statutes, covering internal complaints as well as agency filings and participation in somebody else's claim. Retaliation is a separate claim with its own, often shorter, deadline.
What should I bring to a lawyer?
Your contemporaneous record, what you know about the comparator's role and how you know it, and the dates — when the difference began, when you learned of it, when you raised it.
