U.S. employment law guide
The employment provisions of the Americans with Disabilities Act are primarily found in Title I. They protect qualified applicants and employees from disability discrimination and may require a covered employer to provide an effective reasonable accommodation—unless doing so would cause an undue hardship.
Short answer: Title I is the part of the ADA that directly governs employment. It generally applies to private employers and state or local government employers with at least 15 employees, as well as employment agencies, labor organizations, and joint labor-management committees. Title V contains related provisions, including the ADA’s anti-retaliation rule. Federal executive-branch employees are protected under Section 501 of the Rehabilitation Act rather than ADA Title I, although substantially the same employment standards apply.
Which title of the ADA covers employment?
Title I covers employment. It prohibits a covered entity from discriminating against a qualified individual on the basis of disability in job applications, hiring, advancement, discharge, compensation, training, and other terms, conditions, and privileges of employment. The authoritative starting points are the text of ADA Titles I and V, 42 U.S.C. Chapter 126, Subchapter I, and the EEOC’s implementing rules in 29 C.F.R. Part 1630.
| ADA title | Main subject | Employment relevance |
|---|---|---|
| Title I | Employment | The primary workplace title: recruitment, hiring, pay, promotion, leave, accommodation, discipline, termination, and employment benefits. |
| Title II | State and local government services, programs, and activities | May matter for public entities, including some employment-related questions. The governing procedure and available claims can be complex; public employees should not assume Title II replaces the Title I or Rehabilitation Act process. |
| Title III | Public accommodations and commercial facilities | Covers customer or public access to many private businesses—not the employer-employee relationship. A store may have Title III duties to customers even if it is too small for Title I. |
| Title IV | Telecommunications | Not the principal source of workplace discrimination rights. |
| Title V | Miscellaneous provisions | Includes protection against retaliation and interference with ADA rights. It works alongside Title I in employment cases. |
The Department of Justice provides a broader overview in its Guide to Disability Rights Laws. For workplace issues, however, the EEOC’s disability-employment resources are usually the most directly relevant agency guidance.
Who and what does Title I cover?
Covered organizations
For a private employer, the usual federal threshold is 15 or more employees for each working day in at least 20 calendar weeks in the current or preceding calendar year. The weeks do not have to be consecutive. EEOC summarizes this test on its private-employer coverage page.
Title I also reaches covered state and local government employers, employment agencies, labor organizations, and joint labor-management committees. The statute excludes the United States itself, wholly owned federal corporations, Indian tribes, and qualifying tax-exempt private membership clubs from its definition of “employer.” Other statutes or sovereign laws may still apply.
Covered employment actions
Protection is not limited to firing. It can apply to recruiting, online applications, interviews, testing, conditional offers, hiring, assignments, schedules, workplace access, training, pay, benefits, promotions, discipline, layoffs, termination, references, and employer-sponsored social activities. It also prohibits certain discriminatory standards and tests, harassment based on disability, and discrimination because of a known association with a person with a disability.
Applicants are protected too. You do not have to become an employee before Title I can apply. A qualified applicant may request an accessible application, a sign-language interpreter, extra time made necessary by a disability, or another adjustment to the hiring process.
Who is protected?
The ADA definition of disability has three paths:
- an actual physical or mental impairment that substantially limits one or more major life activities;
- a record or history of such an impairment; or
- being subjected to a prohibited action because of an actual or perceived impairment that is not both transitory and minor.
Major life activities include activities such as seeing, hearing, sleeping, walking, lifting, reading, concentrating, communicating, and working, as well as major bodily functions such as immune, neurological, respiratory, circulatory, digestive, and endocrine functions. An episodic condition or a condition in remission can qualify if it would be substantially limiting when active. With limited exceptions, mitigating measures such as medication, hearing aids, prosthetics, or learned adaptations are not used to erase disability coverage. See the EEOC’s ADA Amendments Act Q&A.
Important distinction: a person relying only on the “regarded as” path can be protected from discriminatory action, but the employer is not required to provide an accommodation on that basis alone. Accommodation generally requires coverage under the actual-disability or record-of-disability path and a disability-related need.
The legal definitions that decide many ADA cases
Statutory definition: an individual who, with or without reasonable accommodation, can perform the essential functions of the employment position the person holds or wants.
The EEOC regulation adds a first step: the person must satisfy the position’s legitimate skill, experience, education, and other job-related requirements. In practice, the analysis is: (1) do you meet the valid prerequisites, and (2) can you perform the essential functions, with or without accommodation? See 29 C.F.R. § 1630.2(m).
Regulatory definition: the fundamental job duties of the position—not its marginal functions. A duty may be essential because the position exists to perform it, few employees can share it, or it requires specialized expertise.
Evidence can include the employer’s judgment, a written job description prepared before recruiting, the time spent on the duty, the consequences of not performing it, a collective bargaining agreement, and the experience of past or current workers in similar jobs. A job description matters, but a label alone is not conclusive; the real work and all available evidence matter. See 29 C.F.R. § 1630.2(n).
A reasonable accommodation is a modification or adjustment that enables a qualified person with a disability to participate in the application process, perform the position’s essential functions, or enjoy equal benefits and privileges of employment. Examples in the statute and regulation include accessible facilities, job restructuring, modified or part-time schedules, reassignment to a vacant position, equipment or device changes, adjusted tests or policies, and qualified readers or interpreters. See 29 C.F.R. § 1630.2(o) and EEOC’s enforcement guidance.
An employer need not provide an accommodation that would cause significant difficulty or expense. This is an individualized assessment—not a synonym for inconvenience. Relevant factors include the accommodation’s net cost, available outside funding or tax benefits, the resources and size of the facility and employer, the structure of operations, and the effect on business operations. If one option creates undue hardship, the employer and worker should consider another effective option. See 29 C.F.R. § 1630.2(p).
How the definitions work together
Consider a delivery driver whose position genuinely requires operating a vehicle for most of each shift. Driving is likely an essential function because it is the reason the job exists. Temporarily assigning a marginal paperwork duty to someone else may be reasonable; permanently removing all driving probably changes the job itself. But if a vacant dispatcher role is available and the driver is qualified for it, reassignment may need to be considered as an accommodation of last resort.
Now consider an accountant whose job description lists “lifting 25 pounds,” but no one in that role has lifted files or equipment for years. The label is evidence, but the actual work, time spent, operational consequences, and experience of other accountants may show that lifting is marginal rather than essential.
Your ADA rights from application through employment
Before a conditional job offer
An employer generally may not ask whether you have a disability, ask questions likely to reveal a disability, or require a medical examination before making an offer. It may ask whether you can perform specific job functions and may ask you to describe or demonstrate how you would perform them, with or without reasonable accommodation. Review the EEOC’s Job Applicants and the ADA and pre-employment medical inquiry guidance.
After a conditional offer
An employer may ask disability-related questions or require a medical exam if it does so for all entering employees in the same job category. A decision based on the results still must comply with the ADA. For example, an exclusionary medical standard may need to be job-related and consistent with business necessity, and the employer may need to consider reasonable accommodation.
After employment begins
Disability-related inquiries and medical examinations generally must be job-related and consistent with business necessity. A request for accommodation can justify limited questions or documentation about the disability and the functional need when those are not obvious. Medical information generally must be kept confidential and in separate medical files, with narrow exceptions. The EEOC explains the rules in its employee medical inquiries guidance.
Protection from retaliation and interference
An employer may not retaliate because a person requested an accommodation, opposed disability discrimination, filed a charge, or participated in an EEO proceeding. Protection can apply even if the underlying discrimination claim ultimately fails, provided opposition activity was based on a reasonable, good-faith belief. Coercing, intimidating, threatening, or interfering with the exercise of ADA rights can also violate the law. See the EEOC’s retaliation guidance.
Association is different from accommodation. The ADA can prohibit an employer from refusing to hire someone because their child has a disability. But the association provision generally does not require a modified schedule so the person can provide caregiving. Employer policies, state law, the FMLA, paid-leave laws, or another statute may provide separate rights.
What reasonable accommodation can look like
Accommodation is individualized. The same diagnosis can create different limitations in different jobs, and the same adjustment may be effective for one worker but not another.
Accessible interview
A deaf applicant requests a qualified sign-language interpreter for a panel interview. If effective and not an undue hardship, the employer generally provides and pays for the interpreter; it should not require the applicant to bring a family member.
Modified communication
An employee with a cognitive disability can perform the job but needs written priorities after meetings and a checklist for multi-step tasks. Changing the communication method may remove the barrier without changing performance standards.
Equipment or workspace
A worker with limited dexterity requests speech-recognition software and an alternative keyboard. Another employee may need a stool, screen magnification, improved lighting, or a quieter workspace.
Schedule or leave
An employee receiving cancer treatment requests a later start on treatment days or a finite period of unpaid leave. Leave can be an ADA accommodation even when ordinary leave policy or FMLA eligibility does not cover the absence, unless it creates undue hardship.
Telework
Remote or hybrid work may be effective when essential functions can be performed from home. It is not automatic: the analysis depends on the job’s actual duties, on-site needs, effectiveness, and hardship. See EEOC telework guidance.
Reassignment
If no accommodation enables an employee to remain in the current job, reassignment to an existing vacant position for which the person is qualified may be required. The ADA generally does not require creating a job, displacing another employee, or promoting the worker.
What the employer usually does not have to do
- remove an essential job function or lower a uniformly applied production or quality standard;
- provide the employee’s preferred option if another accommodation is effective;
- create a new position, bump another employee, or provide a promotion as reassignment;
- provide personal-use items needed both on and off the job, such as ordinary eyeglasses or a prosthetic limb;
- accept a significant safety risk based on objective evidence when reasonable accommodation cannot reduce it;
- excuse indefinite inability to work or erase past misconduct automatically, although accommodation may be needed prospectively.
An employer cannot rely on generalized fear, customer preference, stereotypes, or a blanket “100% healed” rule. A claimed direct threat must involve a significant risk of substantial harm that cannot be eliminated or reduced by accommodation, based on an individualized assessment using current medical knowledge or the best available objective evidence.
How to request a reasonable accommodation: step by step
No special form or legal phrase is normally required. Under EEOC guidance, you can use plain English and need not say “ADA” or “reasonable accommodation.” A family member, health professional, or other representative may sometimes make the request for you. Still, a clear written request creates a useful record.
- Identify the workplace barrier. Focus on the job function, application step, schedule, policy, tool, or environment that is difficult because of a medical condition—not only the diagnosis.
- Check the employer’s process. Review the handbook or intranet for an accommodation coordinator, HR contact, or form. You may also tell a supervisor or another appropriate management representative; an internal procedure should not be used to ignore a clear request.
- Connect the need to the medical condition. Say that you need a change or adjustment at work because of a physical or mental condition. You do not need to disclose every detail of your medical history.
- Describe a workable solution. Suggest one or more options and explain how they would let you apply, perform essential duties, or access equal benefits. Ask to discuss alternatives if your first option is not workable.
- Make and preserve a written record. Record the date, recipient, request, follow-up, documents provided, and response. If you requested verbally, send a short confirmation email.
- Respond to a focused documentation request. If the disability or need is not obvious, the employer may request reasonable documentation establishing disability and functional limitations. The request ordinarily should not demand unrelated records or your complete medical file.
- Participate in the interactive process. Discuss essential functions, limitations, effectiveness, timing, and alternatives. Both sides should communicate promptly and in good faith. Unnecessary delay can itself create a problem.
- Confirm the decision and review effectiveness. Ask for the approved accommodation, start date, duration, confidentiality arrangements, and review date in writing. If it does not work or circumstances change, resume the interactive process.

How to raise a concern and file an EEOC charge
Do not wait for an internal process to finish. For most private-sector and state or local government claims, an EEOC charge generally must be filed within 180 calendar days of the discriminatory act. The limit may extend to 300 days where a state or local agency enforces a law prohibiting the same type of discrimination. Internal grievances, negotiations, union procedures, or accommodation discussions usually do not stop the federal filing clock. Confirm the deadline with the EEOC or a lawyer immediately.
Before filing
- Create a dated timeline of requests, meetings, statements, decisions, and adverse actions.
- Preserve job postings, job descriptions, policies, evaluations, schedules, emails, messages, medical-request letters, and accommodation proposals you lawfully possess.
- Write contemporaneous notes identifying who said what, when, where, and who witnessed it.
- Identify each discrete act—such as refusal to hire, denial of accommodation, demotion, or termination—and its date. Do not assume an older act becomes timely because its effects continue.
- Check the employer’s approximate size and whether a state or local fair employment law offers broader coverage.
- Consider a prompt internal report to HR, management, an EEO officer, or the union, but protect the external deadline.
Private-sector and state/local government process
- Confirm the correct deadline and agency. Read the EEOC’s filing-deadline guidance. A state or local Fair Employment Practices Agency (FEPA) may have different deadlines, cover smaller employers, and accept a charge for dual filing.
- Start intake. Use the EEOC Public Portal to submit an inquiry and schedule an interview, visit an EEOC field office, or write to the EEOC. Calling 1-800-669-4000 can start a discussion, but the EEOC states that it does not take a charge by telephone.
- Do not confuse an inquiry with a charge. A charge is a signed statement alleging employment discrimination and asking the EEOC to act. Complete and sign the charge by the deadline. If time is short, tell the EEOC immediately and follow its expedited instructions.
- Give concrete facts. Include your contact information, the employer’s contact information and approximate employee count if known, what happened, when it happened, why you believe disability or protected activity was involved, and your signature. See How to File a Charge.
- Ask about dual filing. EEOC and many FEPAs have work-sharing agreements. Confirm whether your charge will be filed with both agencies and whether any separate state or local step is required. Use the EEOC FEPA directory.
- Follow the case and consider mediation. The employer will receive notice. Eligible cases may be offered voluntary mediation; otherwise the EEOC may investigate, request information, interview witnesses, or ask the employer for a position statement. Keep contact information current and meet response deadlines.
- Review the outcome carefully. If the EEOC finds reasonable cause, it generally attempts conciliation. If it does not find cause or closes the matter, it may issue a Notice of Right to Sue. The notice is not a ruling that discrimination definitely did or did not occur.
- Calendar the lawsuit deadline. An ADA plaintiff generally needs a Notice of Right to Sue before filing in federal court and usually has 90 days after receipt to sue. Read the EEOC’s lawsuit guidance and consult counsel promptly—well before the notice arrives if possible.
Federal employees and federal job applicants
The process is different. Federal executive-branch employment is governed principally by Section 501 of the Rehabilitation Act, not Title I as a direct cause of action. Generally, you must contact an EEO counselor at the employing or hiring agency within 45 days of the discriminatory matter or effective date of a personnel action. If counseling or ADR does not resolve the issue, the counselor provides notice explaining how to file a formal complaint; that complaint is generally due within 15 days after receiving the notice. Start with the EEOC’s federal-sector process overview.
Deadlines can turn on facts. Rules differ for a discrete act, an ongoing hostile environment, repeated accommodation denials, amended charges, and equitable extensions. Do not calculate a deadline from this article alone. Contact the EEOC, the relevant FEPA, or an employment lawyer as soon as possible.
Important limits: small employers and foreign jurisdictions
Employers with fewer than 15 employees
A small private employer is generally outside ADA Title I if it does not meet the statutory 15-employee/20-week test. That does not necessarily mean the worker has no protection:
- state, county, or city disability-discrimination laws may cover employers with fewer than 15 employees;
- a state or local government employer can present additional Title II or Rehabilitation Act issues, regardless of its size;
- an entity receiving federal financial assistance may have duties under Section 504 of the Rehabilitation Act;
- a federal contractor may have obligations under Section 503 of the Rehabilitation Act;
- leave, workers’ compensation, paid-sick-leave, pregnancy-accommodation, or other laws may apply independently;
- Title III may govern a business’s accessibility to customers or members of the public even when Title I does not govern its employment relationship.
Coverage disputes can also involve related companies, staffing arrangements, franchises, or employee classification. Do not assume a headcount from one office or one payroll answers the legal question.
Work in the United States for a foreign employer
According to the EEOC’s multinational-employer guidance, employees working in the United States or U.S. territories for covered employers are generally protected by federal EEO laws regardless of citizenship. A narrow treaty or other binding international agreement may affect a foreign employer’s obligations. EEO coverage does not itself confer immigration status or work authorization.
Work outside the United States
ADA coverage is not worldwide. In general:
- a U.S. citizen working abroad for a U.S. employer, or for a foreign company controlled by a U.S. employer, may be protected;
- a non-U.S. citizen working outside the United States and its territories is generally not protected by the federal EEO statutes administered by the EEOC, even if the employer is American;
- whether a foreign entity is controlled by a U.S. employer depends on factors such as interrelated operations, common management, centralized labor relations, and common ownership or financial control;
- an employer may have a “foreign laws” defense if complying with the ADA would cause it to violate the law of the country where the workplace is located.
For a remote employee, the relevant workplace, employer identity, citizenship, contract structure, and location of the challenged decision may all matter. Local disability, labor, privacy, and procedural laws may provide different or additional rights. Cross-border workers should consult counsel qualified in each relevant jurisdiction rather than assuming that a U.S. headquarters makes every overseas role subject to the ADA.
Related public-sector rule: federal agencies are covered by the Rehabilitation Act. State and local governments are covered by Title I when its requirements are met and may also have obligations under Title II or Section 504. Remedies and procedural routes can differ, including issues involving governmental immunity, so public employees should obtain case-specific advice.
