What Is the Interactive Process Under the ADA?

The interactive process under the ADA is the informal, back-and-forth conversation an employer and an employee (or job applicant) are expected to have when a disability calls for a workplace change, with the goal of identifying a reasonable accommodation that lets the person do the job. The phrase does not appear in the statute itself. It comes from the EEOC’s regulation at 29 CFR § 1630.2(o)(3), which says a covered employer may need to “initiate an informal, interactive process with the individual with a disability” to pin down the person’s limitations and the accommodations that could address them.¹

The underlying duty comes from Title I of the ADA, which bars covered employers from discriminating against qualified individuals with disabilities in hiring, pay, advancement, discharge, and other terms of employment.² Title I reaches employers with 15 or more employees for each working day in at least 20 calendar weeks in the current or preceding year.³ If your employer is smaller than that, the ADA’s accommodation rules do not apply, though a state law may. Federal employees are covered by the Rehabilitation Act rather than Title I.

What Triggers the Process

The conversation usually starts when an employee tells the employer that a medical condition is making some part of the job difficult. There are no magic words. You do not have to say “reasonable accommodation,” cite the ADA, or put anything in writing. Telling your supervisor that your condition is getting in the way of a specific task is enough to trigger the employer’s duty to engage.⁴ A family member, doctor, or other representative can make the request for you.

Employers can also start the conversation on their own. If a manager sees an employee visibly struggling and has reason to believe a disability is involved, the employer should raise the question rather than wait for a formal request. Ignoring obvious signs does not shield the employer from liability.

What the Conversation Should Cover

The process is not a rigid checklist, but a real back-and-forth generally moves through the same stops:

Acknowledge the request promptly. Sitting on it can itself violate the ADA.
Talk through how the disability affects specific job tasks. The focus belongs on what is hard and what might help, not on the diagnosis.
If the disability or the need for accommodation is not obvious, the employer may ask for reasonable medical documentation confirming the disability and describing functional limitations. Documentation supports the conversation; it does not replace it.⁴
Brainstorm options together. The employer should ask the employee for ideas, since the person living with the condition often has the clearest sense of what would work.
Choose an effective accommodation and put it in place.
Check back later. If the accommodation stops working or circumstances change, re-engage.

How Fast the Employer Has To Move

The ADA does not set a number of days. The EEOC’s guidance is to act expeditiously, and unnecessary delay in responding to or providing an accommodation can itself amount to a denial.⁴ Context matters. The EEOC has said that leaving a request for an accessible parking space untouched for two months is a violation, while a three-month wait for specialized adaptive equipment was acceptable because the employer ordered it immediately and no other vendor carried it. The factors are why the delay happened, how long it lasted, what the employer did during it, and whether the accommodation was simple or complex to arrange.

Interim Accommodations

When the final accommodation will take time, the employer should consider something temporary in the meantime. The EEOC’s internal procedures flag two situations for interim measures: when there is already enough information to believe the employee will qualify while final medical documentation catches up, and when the accommodation has been approved but cannot be delivered right away, such as while equipment is on order.⁵ Communication during any wait matters a great deal.

The Question the Whole Process Is Trying To Answer

Every interactive process circles one question: can this person perform the essential functions of the job with or without a reasonable accommodation? Essential functions are the core duties that define why the position exists. If a job exists to answer phones, answering phones is essential. If a receptionist occasionally sorts mail but the role was not created for that, sorting mail is a marginal duty that can be reassigned.⁶ Employers are not required to strip essential functions out of a job, but they can redistribute marginal ones or change how they are done.

Reasonable accommodations themselves cover a wide range: making facilities accessible, restructuring jobs, changing schedules, providing equipment, modifying policies, and reassigning the employee to a vacant position. The statute uses “may include,” so the list is not closed. Telework, extra leave beyond company policy, and temporary job coaches can qualify depending on the circumstances.³

Whose Preference Wins

You can suggest any accommodation you think would work, and the EEOC says your preference should get “primary consideration.” The employer has the final say, though, as long as the choice is effective. If two options both solve the problem and one costs less, the employer can pick the cheaper one.⁴ What the employer cannot do is pick a cheaper option that does not actually let you do the job. An accommodation that fails in practice is not effective, and the conversation has to restart.

Reassignment to a vacant position is treated as the accommodation of last resort. It comes into play only after both sides have concluded that no accommodation would let the employee do the current job, or that every option would be an undue hardship. The employer does not have to bump anyone else out of a role or create a new one, and the employee must be qualified for the vacancy.⁴

When the Employer Can Say No

An employer does not have to provide an accommodation that would cause an undue hardship, which the statute defines as significant difficulty or expense. The assessment looks at the nature and cost of the accommodation, the financial resources of the facility, the number of employees there and the impact on operations, and the overall size, resources, and structure of the employer. What is an undue hardship for a 20-person shop may be entirely manageable for a Fortune 500 company.³ The burden of proof is on the employer, and vague claims about cost or inconvenience are not enough.

An employer can also decline an accommodation if the employee poses a “direct threat” to the health or safety of others that cannot be reduced through accommodation. That call has to rest on an individualized assessment using current medical evidence, not stereotypes about a condition.⁷

When the Process Breaks Down

The interactive process is a shared obligation, and courts look at who caused the breakdown. This is where most accommodation claims turn.

An employer that ignores a request, drags its feet, or flatly refuses without exploring alternatives is exposed. Good-faith effort during the interactive process is a statutory defense against compensatory and punitive damages under 42 U.S.C. § 1981a, and skipping the conversation throws that defense away.⁴

Employees have obligations too. If the employer reasonably asks for medical documentation and the employee will not provide it, the employer may be justified in denying the request. If an employee needs an accommodation to do essential functions and refuses an effective one the employer offers, the employee may no longer be “qualified” for the job, which can give the employer grounds for further action, including termination.⁴

Both sides should document as they go. The EEOC recommends that employers keep a record of what was requested, what the employer did in response, what was said in discussions, whether medical documentation was requested and provided, and the reasons behind the final decision.⁴ If you are the employee, keep copies of your request (if it was verbal, follow up with an email confirming what you asked for), any medical documentation you submitted, and the employer’s responses. If things fall apart, those records are what you will have.

Confidentiality of Medical Information

Any medical information the employer collects during the process has to be treated as a confidential medical record and stored separately from the general personnel file. It can be shared only with supervisors and managers who need to know about work restrictions, first aid and safety personnel if the condition may require emergency treatment, and government officials investigating ADA compliance.⁷ Sharing a diagnosis with coworkers who do not need the information violates the ADA even if the accommodation itself was handled well.

If the Process Fails

If you believe your employer violated the ADA, you cannot go straight to court. You have to file a charge of discrimination with the EEOC first.⁸ You generally have 180 calendar days from the discriminatory act to file, extended to 300 days if a state or local agency enforces a similar law, which is the case in most states.⁹ These deadlines are strict, and missing them usually ends the claim.

After the EEOC investigates, it will issue a Notice of Right to Sue. You can also request one before the investigation finishes if you want to move to court sooner. Once you have the notice, you have 90 days to file suit.⁸
