ADA Interactive Process Flow Chart: Steps, Hardship, EEOC Deadlines

The ADA interactive process steps are a structured back-and-forth between an employer and an employee designed to find a workable accommodation for a disability: the employee raises a need, the employer gathers medical information, both sides brainstorm options, the employer evaluates them against undue hardship, and the chosen accommodation gets implemented and followed up on. Federal law treats a failure to engage in this conversation as a form of discrimination on its own, separate from whether an accommodation is ultimately provided.¹ That makes the process itself the thing to get right.

Who Has to Follow the Process

Title I of the ADA applies to private employers with fifteen or more employees for each working day in at least twenty calendar weeks during the current or preceding year, and to state and local governments regardless of size.² Federal employees have similar protections but under the Rehabilitation Act, not the ADA. The law protects “qualified individuals”: people who can perform the core duties of the job with or without a reasonable accommodation.

Step 1: The Request That Starts It

The process begins when an employee tells the employer they need some kind of change at work because of a medical condition. No specific language is required. The employee does not need to say “ADA,” “reasonable accommodation,” or any legal term. A plain statement that a health condition is making it hard to do part of the job is enough.³ Something like “my back injury makes it painful to sit at my desk all day” qualifies. A family member calling to explain a hospitalization qualifies too.

Employers also have to start the conversation on their own when they have direct knowledge that a disability is interfering with an employee’s work. Waiting for paperwork is not an option if the need is obvious. Once either side raises the issue, the clock is running, and unnecessary delays in responding can create liability by themselves.

Step 2: Medical Documentation

After a request, the employer can ask for medical documentation to confirm the employee has a disability under the ADA’s definition: a physical or mental impairment that substantially limits one or more major life activities.⁴ The doctor does not need to disclose a specific diagnosis. What matters is the functional gap: which job tasks are affected, and how severely.

Good documentation is concrete. If a job requires lifting thirty pounds and the employee’s current limit is ten, that’s what the paperwork should say. Both sides then have something to work with.

Who Pays

If the employer accepts the employee’s own doctor’s note, the employee typically covers that cost. If the employer requires a visit to a health professional of the employer’s choosing, the employer pays for it.³

Confidentiality

Any medical information collected has to be stored in a separate file, apart from the regular personnel record, and treated as confidential.¹ Only narrow disclosures are allowed:

Supervisors and managers may be told about necessary work restrictions and the accommodation itself, but not the diagnosis.
First aid and safety personnel may be told if the disability might require emergency treatment.
Government investigators looking into ADA compliance may request relevant information.

Casually mentioning a condition to coworkers falls outside those categories and violates the statute. This is one of the most commonly missed pieces of the process.

Step 3: Identifying Accommodations

With medical information in hand, both sides match the employee’s restrictions against the core duties of the job. The written job description matters, but only as evidence of what’s essential, not the last word.² What the employee actually does day-to-day is what counts.

The EEOC recognizes several broad categories of reasonable accommodations:

Making facilities accessible, through ramps, accessible restrooms, or adjustable desks.
Job restructuring, such as reassigning marginal duties to another employee.
Modified schedules, including flexible start times, compressed workweeks, or extra breaks.
Equipment changes, like ergonomic chairs, screen-reading software, or amplified phones.
Policy adjustments, such as allowing a service animal, modifying a dress code, or permitting telework.
Reassignment to a vacant position, as a last resort.

This is a brainstorming phase. The employee usually knows best what would help; the employer usually knows best what is operationally feasible. An employer who simply says “we can’t do that” without exploring alternatives is inviting a claim.³

Interim Accommodations

The process can take time, especially when documentation goes through multiple rounds or when specialized equipment has to be ordered. During that gap, employers should consider whether a temporary fix is feasible. The EEOC’s own internal procedures require interim accommodations when the available evidence makes it reasonably likely the employee will ultimately qualify, and many courts view the same approach favorably for private employers. A short-term schedule change or a loaner piece of equipment keeps the employee productive and shows good faith.

Step 4: Weighing Undue Hardship

Not every requested accommodation has to be granted. The employer can decline one that would impose an “undue hardship,” meaning significant difficulty or expense relative to the organization’s resources. The statute lists the factors:²

The nature and net cost of the accommodation.
The financial resources and number of employees at the specific facility.
The overall financial resources and size of the entire organization.
How the accommodation would affect the facility’s day-to-day operations.

A small business with twenty employees and tight margins is judged differently from a Fortune 500 company. “Expensive” alone is not automatically an undue hardship. Cost gets weighed against total resources. And if one option is too burdensome, the employer cannot stop there. The duty is to keep looking for an alternative that works.

Reassignment as a Last Resort

When no accommodation can keep the employee in their current role, the employer has to consider reassignment to a vacant position the employee is qualified for.³ One detail here is easy to miss: reassignment means the employee gets the vacant job if minimally qualified. The employer cannot make the employee compete against outside applicants for it.

Step 5: Implementation and Follow-Up

Once both sides agree on a solution, the employer should put it in writing: what changes are being made, when they start, and whether the arrangement is permanent or time-limited. That record protects both parties.

The EEOC does not set a specific number of days for implementation, but the expectation is that accommodations be provided as quickly as possible. Simple changes like adjusting a schedule or moving a workstation should happen within days. Equipment orders or software installations take longer, and the employer should communicate a realistic timeline and stick to it.

After the accommodation is in place, scheduled check-ins let both sides confirm it is actually solving the problem. Disabilities change over time. What works in January may not work in June. The interactive process is not a single event but a continuing duty that reactivates whenever circumstances change.

If the Employer Says No

Private employers are not required by Title I to issue a written denial, but the employee can ask for one, and it’s a reasonable request. A written explanation forces the employer to articulate specific reasons instead of a vague refusal.

A denial does not end the process either. If the specific accommodation requested is too costly or disruptive, the employer still has to keep working with the employee on an alternative. Closing the file after saying no is one of the fastest ways to turn a good-faith disagreement into a discrimination claim. The EEOC has stated that failing to participate in the interactive process after receiving a request can itself result in liability for failure to accommodate.³

Requests Made After a Bad Performance Review

Employees sometimes disclose a disability and ask for an accommodation only after receiving a poor review. That timing does not excuse the employer from the process. All the steps above still apply.¹

What the accommodation request does not do is erase what already happened. The employer does not have to retract prior warnings or undo earlier discipline. What changes is the path forward: the employer should let the accommodation take effect before evaluating whether performance improves. Disciplining someone for poor performance that a reasonable accommodation would have prevented is where employers get into legal trouble.

When the Process Breaks Down

Courts look at who caused the breakdown. In evaluating whether a delay was unreasonable, the EEOC considers the reason for the delay, how long it lasted, how much each side contributed to it, what the employer was doing in the meantime, and whether the accommodation was simple or complex.³

An employee who refuses to provide requested medical documentation, or ignores repeated attempts to schedule a meeting, weakens their own claim. An employer who sits on a request for months, shuffles it between departments, or keeps asking for information already provided has a hard time arguing good faith. The practical takeaway is the same for both sides: document everything. Save emails, note the dates of meetings, and keep copies of every form. If it lands in front of the EEOC, the paper trail decides who was cooperating and who was dragging their feet.

Deadlines to File With the EEOC

An employee who believes the employer failed to accommodate or refused to engage can file a charge of discrimination with the Equal Employment Opportunity Commission. The general deadline is 180 calendar days from the date the discrimination occurred, extended to 300 calendar days in states or localities with their own agency enforcing a similar anti-discrimination law, which covers most of the country.⁵

Weekends and holidays are counted, though if the last day falls on one, the deadline moves to the next business day. Pursuing an internal grievance, a union process, or mediation does not pause the clock. Missing the deadline usually kills the claim entirely, so anyone who suspects a violation should file early, even while still trying to work things out internally.
