Age Discrimination in Employment Act: Employer Guide

Age discrimination almost never announces itself. Nobody writes down that they want a younger candidate. What they write is high energy, or digital native, or looking for somebody at the start of their career, and every one of those phrases has been read back to an employer in a claim.

The other thing worth knowing before anything else is that the coverage threshold is different from the one you probably have in mind. Title VII starts at fifteen employees. This statute starts at twenty, which means there is a band of businesses covered by one and not the other, and a much larger band covered by state law regardless.

This covers who is protected, what the statute reaches, the language that produces most claims, and the six conditions a severance waiver has to meet before it waives anything. I build the people and records tooling for businesses without an HR department at FirstHR. This is general information rather than legal advice, and severance waivers in particular are worth a lawyer's eye.

What the ADEA Is

The Age Discrimination in Employment Act is the federal statute protecting workers aged 40 and over from employment discrimination on the basis of age. It works much like the other federal discrimination statutes, with two important structural differences.

The first difference is the threshold, at twenty employees rather than fifteen. The second is that the protected class runs in one direction: it protects older workers, so a claim by a younger worker who was passed over in favour of an older one generally does not arise under this statute (Equal Employment Opportunity Commission).

Who It Covers

Coverage has an employer side and an employee side, and small businesses get caught by the employer side less often than by state law.

The final row is the one that matters most for the readers of this page. Concluding that you have eleven employees and are therefore fine answers the federal question and frequently answers nothing about your actual exposure, because many state statutes reach much smaller employers.

What It Prohibits

The prohibition covers the same broad territory as the other discrimination statutes: hiring, firing, pay, promotion, assignments, training, benefits, and any other term or condition of employment (29 U.S.C. 623).

Two specifics are worth calling out because they are less obvious. Age-specific advertising is restricted directly, which is why a job advert stating a preference or a limit based on age is a problem on its own terms rather than only as evidence of a discriminatory decision. And retaliation against somebody who complains or participates in an investigation is separately prohibited, with the same characteristic that it can succeed where the underlying complaint fails.

The Coded Language Problem

Almost no age claim rests on somebody saying they wanted a younger person. It rests on phrases everybody uses without thinking, quoted back from an email or a message thread.

What makes these particularly damaging is where they are usually found. Not in a formal document, which somebody reviewed, but in an internal message written quickly, which nobody reviewed and the author had forgotten about entirely. Discovery does not distinguish between the two.

The fix is not a vocabulary ban, which manifests as people using the same reasoning with different words. It is describing what the job actually needs. If the role requires somebody comfortable learning new software quickly, say that, because it is both accurate and something a candidate of any age can demonstrate.

Age in Hiring

Hiring is where the most avoidable exposure sits, because so much of it is created by form fields nobody examined.

The last row is worth pausing on because the underlying concern is often legitimate. If you genuinely worry that somebody will leave for a bigger role in six months, that is a fair question to ask directly. Writing overqualified in a rejection note is not asking it; it is recording a conclusion in a word that a jury understands as a synonym for old.

Severance Waivers

This is the most technical part of the statute and the part where a small employer is most likely to spend money and get nothing for it. A general release does not waive an age claim. Six conditions must all be satisfied.

The asymmetry at the end of that list is the point to absorb. Where a waiver fails to meet the requirements, the age claim survives and the employee generally keeps the severance you paid, which means a defective agreement is worse than no agreement (EEOC guidance on waivers).

Group Layoffs and the Disclosure

Where severance in exchange for a release is offered to two or more employees aged 40 or over as part of an exit incentive or termination programme, additional obligations attach, and they are more demanding than employers expect.

The consideration period rises from 21 days to 45. And the employer must disclose the class of employees covered by the programme, the eligibility factors, any applicable time limits, the job titles and ages of everybody selected, and the ages of everybody in the same decisional unit who was not selected.

That last item is the one that produces resistance, because it hands an older worker exactly the information needed to see whether the selection had an age pattern. That is its purpose. The practical implication runs backwards into the selection itself: if you would be uncomfortable disclosing the age profile of who was picked and who was not, that discomfort is worth resolving before the decisions are made rather than at the point of disclosure.

State Law Goes Further

State age discrimination laws are where most small businesses actually sit, and they differ from the federal statute in three ways that matter.

Coverage thresholds are frequently much lower, and several states apply from the first employee, which removes the twenty-employee shelter entirely. Some state laws protect against age discrimination without the 40-and-over floor, meaning a younger worker can bring a claim that would not exist federally. And remedies differ, with some states offering damages that are not capped in the way federal remedies are.

The practical upshot for a business under twenty employees is to build the practices anyway. They are cheap, they improve hiring, and the state exposure is real even where the federal statute does not reach you. The detailed regulatory framework for the federal side is set out in the implementing regulations (29 CFR Part 1625).

What to Actually Do

Six practices, none of which cost anything, and most of which improve hiring on their own merits.

Where Small Employers Get This Wrong

Six patterns, and only one of them involves anybody intending to discriminate.

Using a general release and assuming it covers age is first. It does not, and a defective waiver leaves you having paid severance for nothing.

Assuming the fifteen-employee threshold applies is second. This statute starts at twenty, and state law frequently starts far lower than either.

Coded language in adverts and messages is third, and it is the source of most claims. Nobody writes it intending an age preference and everybody reads it as one.

Raising retirement unprompted is fourth. It is usually meant kindly and it is quoted back in full.

Paying severance before the revocation period expires is fifth, which converts a valid agreement into one that was not yet binding when you performed.

And treating a reduction as age-neutral because the criteria were neutral is last. Criteria that are neutral on their face can still land disproportionately on older workers, which is a disparate impact question rather than an intent question, and it is examined through exactly the disclosure the group waiver rules require you to produce.
