Can my employer refuse an accommodation?

A refusal that may be a substitution

Start here, because it’s an outcome that can be misread as a dead end.

Enforcement guidance from the EEOC, the US Equal Employment Opportunity Commission, which enforces federal workplace disability law, is explicit: the employer may choose among reasonable accommodations as long as the chosen accommodation is effective. As part of the interactive process, the employer may offer alternative suggestions and discuss how well they’d remove the barrier. And if there are two possible reasonable accommodations, one costing more or being more burdensome than the other, the employer may choose the less expensive or burdensome one, as long as it’s effective.

Effective, in the guidance’s terms, means it removes a workplace barrier and thereby provides an equal opportunity to apply for a position, to perform the essential functions of a position, or to gain equal access to a benefit or privilege of employment.

That is the effectiveness test for the substitute, and it puts the argument somewhere specific. If you asked for a private office and were offered noise-cancelling headphones, the question isn’t whether you got what you asked for. It’s whether the headphones remove the barrier. If the barrier was unpredictable interruption rather than volume, they don’t, and that’s the ground to make the case on.

Which is why it pays to describe the barrier, not only the fix. A request framed purely as an object gives an employer an object to swap. A request that names what’s going wrong and why gives you a standard to hold the substitute against.

What undue hardship means, and what it doesn’t

In the US framework this is the actual limit, and the guidance is unusually clear that it’s the only one: the sole statutory limitation on an employer’s obligation to provide reasonable accommodation is that no change is required if it would cause undue hardship.

The definition has more in it than people expect. Undue hardship means significant difficulty or expense, and focuses on the resources and circumstances of the particular employer in relation to the cost or difficulty of providing the specific accommodation. It refers not only to financial difficulty but to accommodations that are unduly extensive, substantial or disruptive, or that would fundamentally alter the nature or operation of the business.

Two things follow that are worth holding onto.

It’s relative to the employer. The same accommodation can be a hardship for one organisation and unremarkable for another, because the test looks at that employer’s resources and circumstances. Employer size and resources are among the factors in that case-specific assessment.

It has to be assessed case by case. The guidance says so directly. A blanket policy that a category of adjustment is never provided isn’t the individualised assessment the standard describes.

The guidance also notes that the undue hardship standard under the ADA, the Americans with Disabilities Act, differs from the one courts apply under Title VII of the Civil Rights Act for religious accommodation. If you’ve read about undue hardship in another context, it may not be the same test.

How the UK frames the same limit differently

The UK reaches a comparable place by a different route, and the structural difference matters if you’re trying to work out what your employer has to justify.

Section 20 of the Equality Act 2010 sets out the duty in three requirements. The first is the one most workplace adjustments run through: where a provision, criterion or practice puts a disabled person at a substantial disadvantage compared with people who aren’t disabled, the duty is to take such steps as it is reasonable to have to take to avoid the disadvantage. The second covers physical features, and the third auxiliary aids.

There’s no separate undue-hardship exemption. The limit lives inside the word reasonable, so cost, disruption and practicality are weighed as part of deciding what steps are required rather than raised afterwards as a defence to a duty that otherwise applied.

In practice both systems ask a similar question about proportion. What differs is the structure: in the US the duty is stated and then limited by a named exemption, while in the UK the limit is built into the duty itself.

The UK duty also has a trigger condition worth knowing before you read a refusal as unlawful. Acas, the UK’s public workplace advice service, states that employers must make reasonable adjustments when they know, or could reasonably be expected to know, that someone is disabled. Acas lists the duty as covering employees and workers, contractors and self-employed people hired to do the work personally, and job applicants.

The US side has its own scope conditions. Title I protects a qualified individual with a disability, and the provisions the EEOC enforces apply to employers with 15 or more employees, with federal employees and some others covered through different or overlapping routes. “The only statutory limit is undue hardship” is true of the duty once it applies. It isn’t a statement that every employer owes every requested change to everyone.

The one thing that isn’t negotiable in the UK

Section 20 of the Equality Act contains a provision worth knowing verbatim, because it comes up and people don’t expect it.

A person subject to the duty to make reasonable adjustments is not, subject to express provision to the contrary, entitled to require the disabled person to pay to any extent that person’s costs of complying with the duty.

In plain terms, an employer under the UK duty can’t hand you the bill for complying with it. That covers the employer’s costs of making the adjustment; it isn’t a promise to reimburse anything a reader might buy or commission independently. If a conversation drifts toward you covering the cost of an adjustment the employer is obliged to make, that’s the provision to go and read.

The same section adds that where the requirement concerns providing information, reasonable steps include making sure the information is provided in an accessible format.

What an employer doesn’t have to provide

Separately from undue hardship, US guidance describes categories that fall outside the obligation from the start. A refusal on these grounds isn’t the employer overreaching.

Personal use items. An employer doesn’t have to provide, as a reasonable accommodation, personal use items needed for daily activities both on and off the job. The guidance names prosthetic limbs, wheelchairs, eyeglasses and hearing aids as examples, on the basis that they’re needed away from work too. It also says an employer isn’t required to provide personal amenities such as a hot pot or refrigerator where those aren’t provided to employees without disabilities.

There’s a real exception attached, and it’s the one to reach for: items that might otherwise be considered personal may be required as reasonable accommodations where they’re specifically designed or required to meet job-related rather than personal needs. So the argument isn’t about the object. It’s about whether the need it meets is a need of the job.

Essential functions and production standards. The guidance says an employer isn’t required to eliminate an essential function of a job, and isn’t required to lower production standards, whether qualitative or quantitative, that are applied uniformly to employees with and without disabilities. It adds that an employer may do either if it wishes, but isn’t obliged to.

The important half of that passage is the next sentence: an employer may have to provide reasonable accommodation to enable an employee with a disability to meet the production standard. Not being required to lower the bar is a different thing from not being required to help you reach it, and those get run together in practice.

Where this bites for neurodivergent readers is in how “essential function” gets defined. Whether something is genuinely essential to a role, or merely how the role has always been done, is a question about the job rather than about you, and it’s a fair one to ask.

What to do with a no

First, establish which kind of no it was, because three different refusals need three different responses.

A swap. You’ve been offered something else. The question is whether the substitute removes the barrier. If it does, you have your accommodation in a form you didn’t choose. If it doesn’t, say specifically why not, in terms of the barrier rather than the preference.

A hardship claim. The employer says it costs too much or disrupts too much. Under the US standard that’s a case-by-case assessment against their own resources, and it’s a claim with a shape you can ask about.

A refusal of standing. The employer disputes that the duty applies at all, usually over documentation or over whether you meet the definition. In the UK that definition is section 6 of the Equality Act 2010, which turns on whether an impairment has a substantial and long-term adverse effect on normal day-to-day activities rather than on what it’s called. That’s a different argument from either of the above, and it’s the one where the paperwork question bites.

Then find the people whose job this is. An employment adviser, a union representative, an occupational health service, or a disability rights organisation in your country can tell you what your system provides and what the timelines are. If your employer has an internal escalation or grievance route, check its deadlines, and keep a written record of the request, the response and any alternatives discussed.

What this page can’t do is tell you whether your employer was within its rights, because that depends on your jurisdiction, your employer’s policy, your role and the specific facts. What it can do is stop you accepting a swap you didn’t examine, or treating a substitution as the end of the conversation when the guidance treats it as the middle of one.
