Do Employers Have to Make Reasonable Accommodations? The ADA Duty

In most cases, yes. Under the federal Americans with Disabilities Act (ADA), an employer with 15 or more employees generally must provide a reasonable accommodation to a qualified worker with a disability - unless doing so would cause the business a significant difficulty or expense, known as "undue hardship." The duty is real, but it has limits and a specific process, and that is exactly where most disputes begin.

This article explains the federal baseline, when a refusal crosses the line into illegal discrimination, and the practical steps to protect yourself. It is general information, not legal advice for your specific situation.

The Federal Baseline: The ADA

The Americans with Disabilities Act, enforced by the U.S. Equal Employment Opportunity Commission (EEOC), is the main federal law requiring private employers to accommodate disabilities. Title I of the ADA covers employment. A nearly identical duty applies to federal-sector and many federally funded employers under the Rehabilitation Act of 1973.

Three threshold facts decide whether the ADA duty applies to you:

• Employer size. The ADA covers private employers, as well as state and local governments, with 15 or more employees. Smaller employers are not covered by the federal ADA - but many states extend protection to much smaller workplaces (this varies by state).
• You have a "disability" as defined by law. This means a physical or mental impairment that substantially limits a major life activity (such as walking, seeing, concentrating, sleeping, or the operation of a major bodily function). It also covers a record of such an impairment, or being regarded as having one. After the ADA Amendments Act of 2008, this definition is meant to be interpreted broadly. Conditions like diabetes, epilepsy, depression, PTSD, cancer, and many others can qualify.
• You are "qualified." You must be able to perform the essential functions of the job - the core duties - with or without a reasonable accommodation. The point of an accommodation is to let a qualified person do those essential functions.

What Counts as a Reasonable Accommodation?

A reasonable accommodation is a change to the job, the workplace, or the way things are usually done that lets a worker with a disability perform the job or enjoy equal benefits of employment. Common examples include:

• Modified or part-time schedules, or adjusted break times (for example, for medical treatment or to manage symptoms).
• Leave for treatment or recovery, even unpaid leave, as an accommodation.
• Physical changes such as accessible workstations, ergonomic equipment, ramps, or assistive technology.
• Reassignment to a vacant position the employee is qualified for, when they can no longer do their current job.
• Allowing a service animal, permitting telework where feasible, or providing readers or interpreters.
• Adjusting how a job is performed, or reallocating marginal (non-essential) tasks.

Importantly, the employer does not have to provide the exact accommodation you request. It must provide an effective one. If two options both work, the employer may generally choose the less expensive or easier one.

The ADA also does not require an employer to: eliminate an essential function of the job, lower production or performance standards that apply to everyone, tolerate misconduct (even disability-related misconduct), or provide personal-use items like everyday eyeglasses or a wheelchair for use off the job.

The "Interactive Process": The Step Most Disputes Hinge On

Once you ask for a change at work because of a medical condition, the law expects both sides to engage in an "interactive process" - a good-faith, back-and-forth conversation to identify the limitation and find a workable accommodation. You do not need to use the words "ADA" or "reasonable accommodation" or even "disability." Simply telling your employer you need an adjustment for a medical reason is usually enough to trigger the employer's duty to respond.

During this process, the employer may ask for reasonable medical documentation confirming the disability and the need for accommodation - but only when the disability or need is not obvious. An employer that ignores a request, drags its feet indefinitely, or refuses to discuss alternatives may be violating the ADA, even if an accommodation would ultimately have been hard to find. A breakdown in the interactive process caused by the employer is itself a frequent basis for liability.

When Does Refusal Become Illegal?

An employer's denial is generally lawful only if providing the accommodation would impose an undue hardship - meaning significant difficulty or expense judged against the employer's size, resources, and operations. "It's a little inconvenient" or "we've never done that" does not meet that bar. A refusal is more likely to be illegal when the employer:

• Never responds to or discusses the request at all.
• Denies the request without offering any alternative and without showing real hardship.
• Demands excessive or unnecessary medical information, or discloses your medical information to coworkers.
• Punishes, demotes, fires, or otherwise retaliates against you for asking. Retaliation for requesting an accommodation is independently illegal under the ADA - even if the underlying accommodation request turns out not to be required.

How the ADA Interacts With Other Laws

Your situation may be covered by more than one law at the same time:

• The Family and Medical Leave Act (FMLA), enforced by the U.S. Department of Labor Wage and Hour Division, can provide job-protected unpaid leave for a serious health condition at employers with 50 or more employees, for eligible workers. Leave can be both an FMLA right and an ADA accommodation.
• The Pregnant Workers Fairness Act (PWFA), enforced by the EEOC, requires covered employers to reasonably accommodate known limitations related to pregnancy, childbirth, and related conditions - a separate, often easier-to-meet standard than the ADA.
• State and local disability laws. Many states and cities require accommodations from smaller employers, define disability more broadly, or give workers more time to file and stronger remedies. This varies by state, so check your state's fair employment or civil rights agency.

Practical Steps to Protect Yourself

Whether you are a worker seeking an accommodation or an employer trying to do this right, documentation and process matter enormously.

If You Are the Employee

• Put your request in writing. A short, dated email stating that you need an adjustment at work for a medical condition creates a clear record of when the duty was triggered.
• Be specific about the limitation, not just the diagnosis. Explain what you struggle with (for example, "I can't stand for long periods") and suggest an accommodation if you have one in mind.
• Keep records. Save emails, notes from meetings (with dates and who was present), denials, and any medical paperwork you provide.
• Get supporting documentation from your provider if asked - focused on your limitations and needs, not your entire medical history.
• Stay engaged. Respond to the employer's questions and proposed alternatives. Courts look closely at who caused any breakdown in the interactive process.

If You Are the Employer

• Treat any request for a work change tied to a medical condition as a possible accommodation request, and respond promptly.
• Engage in the interactive process and document your good-faith efforts and the options you considered.
• Keep all medical information confidential and stored separately from regular personnel files.
• Only claim undue hardship when you can actually show significant difficulty or expense - and consider less costly alternatives first.

How to File a Complaint

If your employer refuses to accommodate or retaliates against you, you can file a Charge of Discrimination with the EEOC. Filing is free, and you do not need a lawyer to start. There is a strict deadline: under federal law you generally have 180 days from the discriminatory act to file with the EEOC, extended to 300 days in states that have their own anti-discrimination agency. Because the exact deadline depends on your state, do not wait - confirm your timeline as early as possible.

You can begin online through the EEOC's public portal, by phone, or at a field office. Many states also let you file with a state fair employment agency, which can have different (sometimes longer) deadlines. After investigating, the EEOC may attempt to resolve the matter or issue a "right to sue" notice that lets you take the case to court. Filing a charge with the EEOC (or the appropriate state agency) is usually a required step before you can sue under the ADA.

The bottom line: covered employers do have a genuine legal duty to accommodate qualified workers with disabilities, the process is supposed to be collaborative, and refusing without real hardship - or punishing you for asking - is where a denial turns into an illegal act you can challenge.

The law behind your rights at work

The ADA requires reasonable accommodation and an interactive process; the EEOC enforces it.

Key federal laws:

• Americans with Disabilities Act (ADA), 42 U.S.C. § 12101 et seq.

Where to get help or file a complaint:

• U.S. Equal Employment Opportunity Commission (EEOC) — file a charge

Your state and city matter. Federal law is the floor — many states and cities require higher pay, more leave, and broader protections. Always check your state’s rules (and any local ordinances) in addition to the federal laws above. This is general legal information, not legal advice.
