What Counts as Comparable Work

The three factors, and what each is asking

Skill asks what the job requires in ability, experience, training and education — but requires of the job, not of the person holding it. Somebody with a doctorate performing work that needs none brings the qualification with them; it does not become a requirement of the role because they happen to have it. This is the distinction that catches people most often, because it feels natural to compare two people rather than two jobs.

Effort covers the physical and mental exertion the work actually demands. It is measured by what the job involves rather than by how hard somebody finds it, and mental effort counts equally with physical. A role requiring sustained concentration and judgment can involve as much effort as one requiring lifting, and the law does not rank them.

Responsibility asks about accountability — the consequences of an error, the degree of supervision received, and whether the person makes decisions that bind the organization. A difference in responsibility is one of the most common and most legitimate reasons two similar-looking jobs are paid differently, and it is also one of the easiest to assert without evidence. An employer saying one role carries more responsibility should be able to name what that responsibility is and what happens when it goes wrong.

Working conditions and establishment

Beyond the three factors, the jobs must be performed under similar working conditions, which covers the physical surroundings and any hazards involved. Outdoor work in extreme weather is a different working condition from an office; exposure to hazardous materials is a difference; ordinary variations in desk arrangements are not. The factor exists to stop genuinely different environments being compared, not to let an employer distinguish two office jobs by their furniture.

They must also be at the same establishment, which usually means the same physical place of business rather than the same company. That limit matters and it has been narrowed by several states, which now allow comparisons across locations within a county, a region, or the whole employer. If your comparator works at a different site, whether you can use them is a state-law question before it is anything else. Establish that first, because it can rule a comparator in or out before any of the three factors matter.

What does not count, and why that surprises people

Job titles carry no weight. Two people titled Analyst can be doing entirely different work, and a Coordinator and a Manager can be doing the same. A title is a claim about a job rather than a description of it, and the law looks past it in both directions.

The written job description carries very little weight either, and this is the one that genuinely surprises employers. A description written three years ago that no longer matches the work does not define the job for this purpose; the work as actually performed does. That cuts against an employer relying on paperwork and equally against an employee relying on it.

Nor does the comparison require the jobs to be identical. The standard is equal work rather than the same work, meaning substantially equal in skill, effort and responsibility. Minor differences in tasks do not defeat a comparison, and an employer arguing that two jobs differ has to show the difference is substantial rather than merely real.

Picking a comparator

The choice of comparator is the single most consequential decision in a pay equity question, and it is worth taking real time over rather than reaching for the obvious candidate. The right comparator makes a weak-feeling situation concrete, and the wrong one makes a strong situation collapse on a single distinguishing fact. You need a specific person of the opposite sex, at the same establishment or within whatever range your state allows, whose job is substantially equal to yours on all three factors.

A useful test is to write out both jobs as they are actually performed — the recurring tasks, the decisions each person makes alone, who they supervise, what happens if they get something wrong — and then look for the differences yourself before anybody else does. If you can find a substantial difference in responsibility, so can the employer, and it is better to know that at the start than after raising it. Doing the employer’s work first is uncomfortable and it is the only way to find out whether you have something.

Where several possible comparators exist, the strongest is usually the one most similar on responsibility rather than the one paid most. A comparison against somebody paid far more but carrying genuinely greater accountability is weaker than a comparison against somebody paid moderately more doing genuinely the same work. Size of the gap is not the same thing as strength of the claim, and people reliably confuse the two.

Building the comparison

Document both jobs rather than just your own, because the comparison is the claim. Keep your own records of what you actually do — recurring responsibilities, projects owned, decisions made without approval, people supervised — and gather what you legitimately can about the comparator’s role from ordinary sources: the posting it was advertised under, the organizational chart, published team descriptions. None of that requires anybody’s cooperation and all of it is the sort of thing employees see in the normal course of work.

Legitimately is the operative word. Information learned in conversation with colleagues is fine, and discussing pay with coworkers is protected for most private-sector employees. Accessing systems you have no business in is a different act with its own consequences, and it can damage a claim that would otherwise have been strong.

Contemporaneous notes matter more than reconstructions. A dated record of what you were doing in a given month is worth considerably more than a recollection assembled after a dispute begins, and it costs a few minutes a week to keep. Start it now rather than when you need it, because the value of the record is entirely in its having existed before the question arose.

Where state law widens the comparison

The federal standard is equal work. Several states have adopted substantially similar work, which is a looser test allowing comparison between jobs that are alike without being equivalent. A smaller group has gone further to comparable work, permitting comparison between different jobs judged to be of comparable value to the employer.

That progression matters more than any other detail here, because it changes who counts as a comparator. Under a comparable-work standard, roles in different departments doing entirely different tasks can be compared if their value to the organization is comparable — which is a much larger claim and a considerably harder one to evaluate. The first is settled by task lists; the second needs a job evaluation framework, which is why comparable-work claims are harder to bring and harder to defend.

So the first thing to establish is which standard applies where you work. A comparison that fails under the federal test may succeed under your state’s, and no national article can tell you which situation you are in, this one included. It is one lookup on your state labor department’s site and it should come before anything else here.

This is general information about how the comparison is structured rather than legal advice about your job. Whether two specific jobs are substantially equal is a fact-intensive question that turns on details, and an employment lawyer or your state agency is the place to test it — there are also deadlines, so asking early costs nothing and waiting can cost the claim.
