How to Request a Reasonable Accommodation at Work – The Complete Script and Letter Template
Marcus Torres had worked as a customer service supervisor at a regional insurance company for six years when his multiple sclerosis began producing significant fatigue — not the kind that responds to coffee, but the kind that makes a standard 8:00 to 5:00 schedule genuinely difficult to manage. His neurologist recommended a flexible start time, ideally between 9:30 and 10:00 a.m., which would allow him to complete his morning medication and PT routine without rushing. Marcus mentioned this to his direct manager informally one morning. The manager said she’d “look into it.” Three weeks passed. Nothing happened. Marcus didn’t follow up because he wasn’t sure he was entitled to anything specific, didn’t want to seem like he was making demands, and had no idea there was a legal process with specific steps and timelines.
Four months later, his performance review cited “attendance irregularities.” He had been arriving at 9:45 a.m. because he physically could not arrive earlier without medical consequence.
What Marcus didn’t know was that a casual mention to a supervisor is not a reasonable accommodation request under the ADA. The law provides specific rights — but those rights don’t activate on their own. There is a process, and understanding it changes what you’re entitled to ask for, how to ask for it, and what your employer is required to do in response.
For a broader foundation on your workplace disability rights, our ADA rights at work guide covers what the ADA protects, who it covers, and what employers can and cannot do.
What a Reasonable Accommodation Actually Is — and What It Isn’t
Under 42 U.S.C. §12111(9), a reasonable accommodation is any modification or adjustment to a job, work environment, or the way work is performed that enables a qualified individual with a disability to enjoy equal employment opportunity. The statute provides three categories:
- Modifications to job application processes — for the hiring stage
- Modifications to work environment or job performance — the most common category for current employees
- Modifications that enable equal enjoyment of benefits and privileges of employment — training programs, break rooms, company events
Common examples include schedule modifications (Marcus’s situation), remote work, modified equipment, leave of absence beyond what FMLA provides, reassignment to a vacant position, and restructuring of non-essential job functions.
What reasonable accommodation is not: a guarantee of the exact accommodation you request, a right to a promotion, a right to the elimination of essential job functions, or a right to an accommodation that creates undue hardship for the employer. The word “reasonable” carries genuine legal weight — and it is tested against the employer’s size, resources, and the nature of the job.
The undue hardship standard is set out in 42 U.S.C. §12111(10): an accommodation is unreasonable if it requires significant difficulty or expense in relation to the employer’s financial resources, workforce size, and the nature of the operation. A Fortune 500 company denying a $400 ergonomic chair as undue hardship would face a very different EEOC analysis than a 12-person small business making the same argument.
Who Is Protected — and Who Is Not
The ADA applies to employers with 15 or more employees under 42 U.S.C. §12111(5). If your employer has fewer than 15 employees, federal ADA protections do not apply — though many states have equivalent laws covering smaller employers. California’s FEHA covers employers with five or more employees. New York’s Human Rights Law covers employers with four or more.
To qualify for reasonable accommodation, you must be:
- An individual with a disability (a physical or mental impairment that substantially limits a major life activity, a record of such impairment, or being regarded as having such an impairment — 42 U.S.C. §12102)
- Qualified for the job — meaning you can perform the essential functions of the position, with or without accommodation (42 U.S.C. §12111(8))
The ADA Amendments Act of 2008 (ADAAA) significantly broadened the definition of disability. Conditions like cancer in remission, epilepsy, major depression, diabetes, and HIV now generally qualify without extensive legal argument. Temporary conditions — a broken leg healing over six weeks — may not qualify depending on circumstances, though some temporary conditions do rise to the level of disability under the amended definition.
One important clarification: you do not have to use the phrase “reasonable accommodation” or cite the ADA to trigger the interactive process. The EEOC Enforcement Guidance (Guidance Number 915.002) is explicit on this point. If you tell your employer you need a schedule change because of a medical condition, that communication is sufficient to initiate the employer’s obligation to engage in the interactive process — even if you never say the words “ADA” or “accommodation.”
The Interactive Process — What Employers Are Required to Do
Once an accommodation request is made, the ADA triggers what courts and the EEOC call the “interactive process” — a good-faith discussion between employer and employee to identify and implement an effective accommodation. Neither side gets to dictate the process or unilaterally declare it over.
Under 29 CFR §1630.9 and the EEOC Enforcement Guidance, an employer who fails to engage in the interactive process in good faith risks liability even if the requested accommodation would have been denied as unreasonable. The process itself is legally required — not just the outcome.
Practically, the interactive process looks like this:
- Employee notifies employer of a need related to a medical condition (written or oral — both count)
- Employer may request medical documentation sufficient to confirm the disability and the functional limitations (not a full medical history — just what’s needed to evaluate the request)
- Employer and employee discuss possible accommodations
- Employer identifies effective options and implements one — not necessarily the one the employee preferred
The employer can choose among effective accommodations. If two accommodations would equally enable the employee to perform essential job functions, the employer may choose the less expensive or less disruptive option — even if the employee prefers the other.
What the employer cannot do: ignore the request, refuse to provide any documentation guidance, unilaterally declare the requested accommodation impossible without evaluating alternatives, or retaliate against the employee for making the request. Retaliation for requesting accommodation is separately prohibited under 42 U.S.C. §12203.
How to Make the Request — Step by Step
This is where most people go wrong. Informal mentions to managers, hoping something will happen, is not the interactive process. Here is how to do it correctly.
Step 1: Put it in writing.
You have the right to make an accommodation request verbally, and the employer must respond. But a written request creates a paper trail, gives you a date, and prevents “I didn’t know you needed anything” from becoming an excuse. Send it to HR — not just your manager — by email, so you have a record.
Step 2: Identify your limitation, not your diagnosis.
You are not required to disclose your specific diagnosis. You are required to identify the functional limitation that is creating the work barrier. “I have a condition that limits my ability to stand for extended periods” is sufficient. “I have lupus and here is my full rheumatology history” is more than the law requires.
Step 3: Name the accommodation you’re requesting.
Be specific. “I’m requesting permission to work from home on Mondays and Wednesdays” is a clear request. “I need some flexibility” is not. The more specific your request, the clearer the employer’s obligation becomes.
Step 4: Offer to provide documentation.
Medical documentation can be requested by the employer when the disability is not obvious or already known. Getting ahead of this by offering to have your physician provide documentation speeds the process and demonstrates good faith.
Step 5: Follow up in writing if there is no response.
If you submit your request and hear nothing for ten business days, send a written follow-up referencing your original request and asking for a timeline. This creates a record that the employer failed to engage — which is relevant if the matter eventually reaches the EEOC.
The Request Letter — Template
Below is a template letter. Adapt every bracketed section to your specific situation. Do not submit a generic letter.
[Your Name] [Your Job Title] [Date]
To: [HR Director/Manager Name], Human Resources CC: [Direct Supervisor Name] Re: Request for Reasonable Accommodation Under the ADA
Dear [HR Director Name],
I am writing to formally request a reasonable accommodation under the Americans with Disabilities Act (ADA), 42 U.S.C. §12101 et seq., in connection with a medical condition that affects my ability to [briefly describe the work function affected — e.g., “maintain a standard 8:00 a.m. start time” / “sit for extended periods” / “work in the open office environment without sound mitigation”].
I am a qualified individual for my position as [Job Title] and I am able to perform all essential functions of this role with the accommodation described below.
Accommodation Requested: [Be specific. Examples:]
- A modified start time of [9:30 a.m.] in place of my current scheduled start of [8:00 a.m.]
- Permission to use a standing desk or alternate seating in my workspace
- The ability to work remotely on [specific days] each week
- [Other specific accommodation]
Reason for Request: I have a medical condition that [briefly describe the functional limitation without disclosing diagnosis if preferred — e.g., “substantially limits my ability to manage fatigue in early morning hours” / “limits my ability to remain seated for extended periods without pain”]. My treating physician has recommended [the accommodation or the functional limitation it addresses].
I am prepared to provide medical documentation from my healthcare provider confirming my functional limitations and the basis for this request. Please let me know what documentation format your organization requires.
I am committed to the success of my role and welcome the opportunity to discuss this request further. I am available for an interactive process discussion at your convenience.
Please confirm receipt of this request and provide a timeline for your response.
Respectfully,
[Your Name] [Your Contact Email] [Your Phone Number]
The Verbal Script — For the First Conversation
Some people prefer to begin with a conversation before sending a formal letter. Here is a script for that conversation:
“I wanted to talk with you about something formal. I have a medical condition that’s been affecting [specific work function]. I’m not asking you to solve it right now — I want to submit a formal accommodation request in writing to HR so we can go through the ADA process properly. I wanted to give you a heads-up first. I’ll be sending the written request this week.”
This script accomplishes three things: it signals seriousness, it avoids an impromptu decision from a manager who may not know the law, and it frames the written request as the starting point — which it should be.
What Happens If the Employer Says No
An employer can legally deny your specific requested accommodation if it constitutes undue hardship or if an equally effective alternative exists. An employer cannot legally deny all accommodation without engaging the interactive process.
If you receive a denial, your next steps depend on how the denial was communicated:
| Situation | Recommended Response |
|---|---|
| Employer offers an alternative accommodation | Evaluate it — if it addresses your limitation, it may be legally sufficient even if not your preference |
| Employer denies without explaining why | Request in writing the specific basis for the denial |
| Employer claims undue hardship | Ask for documentation of the hardship analysis |
| Employer ignores the request | Send a written follow-up and set a 10-day response deadline |
| Employer denies after bad-faith process | File an EEOC charge within 180 days (or 300 days in states with EEOC work-sharing agreements) |
Filing an EEOC charge does not immediately result in a lawsuit. The EEOC investigates, may attempt mediation, and issues a “right to sue” letter if the matter is not resolved — which you need before filing a federal ADA lawsuit. EEOC charges for accommodation violations are filed under 42 U.S.C. §12117. There is no filing fee.
One practical note: many accommodation disputes are resolved without EEOC involvement once the employee demonstrates knowledge of the process. An employer who learns that you know the specific statute, the interactive process requirements, and the EEOC filing timeline may engage more seriously with your request than they did initially.
What Examiners and EEOC Investigators Actually Look For
When an accommodation dispute reaches the EEOC, investigators evaluate the record of both parties. Specifically:
Documentation of the employee’s request: Was it made in writing? What date? What specifically was requested?
Evidence of the employer’s response: Did they engage? Did they request documentation? Did they propose alternatives? Did they explain their reasons?
The interactive process: Was there a good-faith dialogue, or did one party shut it down?
Comparator evidence: Are non-disabled employees permitted to do informally what the disabled employee is asking for formally? (A common pattern: an employer denies flexible scheduling as an ADA accommodation while already allowing informal schedule flexibility for other employees.)
Retaliation timing: Did a negative performance action, demotion, or termination follow the accommodation request within a timeframe suggesting connection?
This is why the paper trail matters. An employer who gave you a negative performance review three weeks after your written accommodation request faces a much harder EEOC defense than one who denied the request, documented the undue hardship analysis, and offered an alternative.
Edge Case: When Your Job Duties Change Before the Request Is Resolved
This situation arises more often than most guides acknowledge. You submit an accommodation request, and while the employer is “evaluating” it, they restructure your role — adding responsibilities that make the accommodation seem less feasible, or moving the position to a different location.
If the job restructuring appears designed to circumvent the accommodation request, that can constitute retaliation under 42 U.S.C. §12203. The EEOC Enforcement Guidance specifically addresses interference with accommodation rights. Document any changes to your role or responsibilities that occur after the accommodation request is submitted, with dates.
This rule technically exists in the statute but in practice is difficult to prove without contemporaneous documentation. The strength of a retaliation claim in this context depends heavily on the timing and the internal communications you can access — which is one reason employment attorneys sometimes advise making accommodation requests with strategic timing awareness.
What Marcus Did Next
Marcus consulted an employment attorney after receiving his performance review. He learned that his informal verbal mention to his manager may have initiated the interactive process — but with no documentation, his employer could plausibly deny that any accommodation request had been made. He submitted a formal written request that week, referencing the EEOC enforcement guidance and citing 42 U.S.C. §12111(9). HR responded within five business days. The schedule modification — a 9:30 a.m. start — was approved within three weeks.
The performance notation about “attendance irregularities” was removed from his file as part of the resolution.
Marcus had the right to that accommodation from the beginning. What he lacked was the knowledge that the informal mention wasn’t enough, and that the law had a specific process with specific employer obligations attached to it.

Frequently Asked Questions
Can my employer require me to disclose my specific diagnosis in order to process my accommodation request?
No. Under the EEOC Enforcement Guidance (Guidance Number 915.002), an employer may request documentation that confirms the existence of a disability and describes the functional limitations — but is not entitled to a full medical history or a specific diagnosis. You can instruct your physician to document your limitations without naming the underlying condition. What the employer needs to evaluate is what you cannot do and what accommodation would address it — not the name of your condition.
How long does an employer legally have to respond to an accommodation request?
What if I need an accommodation for a mental health condition rather than a physical disability?
Mental health conditions that substantially limit major life activities — including depression, anxiety disorders, PTSD, bipolar disorder, and OCD — qualify as disabilities under 42 U.S.C. §12102 and the ADA Amendments Act of 2008. The accommodation process is identical. Common mental health accommodations include schedule modifications, reduced interruptions, remote work, modified supervisory communication, and leave for treatment. Mental health conditions are among the most commonly cited conditions in EEOC accommodation charges, and courts have repeatedly upheld them as qualifying disabilities. If you're also navigating disability benefits related to mental health, the SSI vs SSDI guide explains how work and disability income intersect.
Can my employer reassign me to a different position as my accommodation instead of modifying my current role?
Yes — under the EEOC Enforcement Guidance, reassignment to an equivalent vacant position is a form of reasonable accommodation and is actually considered the accommodation of last resort when no modification of the current position is feasible. The employer must reassign you to a vacant position for which you are qualified — they are not required to create a new position, bump another employee, or give you a promotion. The new position must be equivalent in pay, status, and benefits where possible. Under 42 U.S.C. §12111(9)(B), reassignment is explicitly listed as a reasonable accommodation.
What if I'm a federal employee — does the ADA apply to me?
Federal employees are not covered by the ADA. Instead, federal employees have parallel protections under Section 501 of the Rehabilitation Act of 1973 (29 U.S.C. §791), which applies the same reasonable accommodation standards. The process differs in one important way: federal employees must exhaust the Equal Employment Opportunity (EEO) counseling process within their agency before filing a formal complaint, under 29 CFR Part 1614. The initial counseling contact must be made within 45 days of the discriminatory act — a shorter window than the ADA's 180-day EEOC filing deadline.
Can an employer withdraw an approved accommodation later?
An employer can modify or withdraw an accommodation if circumstances change — for example, if the job's essential functions change significantly, if the accommodation is shown to create undue hardship that wasn't apparent initially, or if the employee's condition improves such that the limitation no longer exists. The withdrawal must go through the interactive process again — the employer cannot unilaterally revoke an approved accommodation without good-faith discussion of alternatives. If you receive notice that an accommodation is being withdrawn, respond in writing and request a meeting to restart the interactive process.
