42 U.S.C. § 12112: Disability Discrimination in Employment
42 U.S.C. § 12112 is a central provision of Title I of the Americans with Disabilities Act (ADA). It bars covered employers from discriminating against qualified people with disabilities in hiring, workplace conditions, advancement, and other employment decisions. The law also addresses reasonable accommodations, disability-related questions, and medical examinations. Knowing what the statute covers—and how its rules work in practice—can help employees and employers identify potential violations and respond appropriately.
What 42 U.S.C. § 12112 Covers
Section 12112(a) makes it unlawful for a covered entity to discriminate against a qualified individual on the basis of disability in connection with an application, hiring, advancement, discharge, compensation, training, or other terms, conditions, and privileges of employment. It is part of Title I of the ADA, the federal law’s employment-discrimination title.
The provision is broader than a ban on refusing to hire someone because of a disability. It can apply to decisions about work assignments, pay, benefits, leave, promotion, training, discipline, and workplace access. It also addresses policies and procedures that may exclude people with disabilities, even when discrimination is not expressed in a job posting or stated as the reason for a decision.
The statute’s definition of “disability” comes from 42 U.S.C. § 12102. It generally includes a physical or mental impairment that substantially limits one or more major life activities, a record of such an impairment, or being regarded as having one. The ADA Amendments Act of 2008 directed that the definition be interpreted broadly. Certain conditions are excluded from coverage, and the legal analysis depends on the facts of the particular situation.
Which Employers and Workers Are Covered
Title I generally applies to private employers, employment agencies, labor organizations, and joint labor-management committees with 15 or more employees. The ADA’s definitions and coverage rules also address state and local government employers. A separate federal-sector provision governs disability discrimination in federal employment, and federal employees generally follow a different administrative complaint process.
Title I does not cover every work arrangement. For example, the statute excludes the United States government from the definition of “employer” for this title; federal workers have protections under other federal laws. Bona fide private membership clubs that are exempt from taxation under the relevant provision of the Internal Revenue Code are also generally excluded from the ADA’s employer definition, except for labor organizations. State and local laws may cover smaller employers or provide additional protections.
Coverage depends on the relationship and circumstances, not simply on the label used by a company. Workers classified as independent contractors may not be employees under Title I, but misclassification can be a separate legal issue. Applicants are protected during the hiring process when the law applies, and an individual does not need to disclose a disability simply to receive ADA protection.
Who Is a “Qualified Individual”
A qualified individual is someone who meets the job’s legitimate skill, experience, education, and other job-related requirements and can perform the position’s essential functions, with or without reasonable accommodation. This standard applies to applicants as well as employees.
Essential functions are the fundamental duties of the job, rather than marginal tasks. Evidence can include the employer’s judgment, a written job description prepared before hiring, how much time the job requires for a task, the consequences of not performing it, and how the work is distributed among employees. A job description is relevant evidence, but it does not automatically settle whether a function is essential.
An employer may set legitimate performance and qualification standards, provided they are job-related and consistent with business necessity when required by the ADA. A person need not be able to perform every task in the exact way the employer traditionally expected if an effective, reasonable accommodation would enable performance of the essential functions.
Prohibited Forms of Employment Discrimination
Section 12112 identifies conduct that can constitute discrimination. Its examples are not limited to direct refusal to hire. The statute prohibits actions such as:
- Unequal opportunities: Limiting, segregating, or classifying an applicant or employee in a way that adversely affects employment opportunities because of disability.
- Contractual arrangements: Participating in a contractual or other arrangement that has the effect of subjecting a qualified person to discrimination.
- Standards and criteria: Using qualification standards, tests, or selection criteria that screen out or tend to screen out people with disabilities, unless the criteria are job-related and consistent with business necessity and the job cannot be performed with a reasonable accommodation.
- Accommodation failures: Failing to make a reasonable accommodation for known limitations of a qualified applicant or employee, unless the employer can show undue hardship.
- Association discrimination: Excluding or denying equal jobs or benefits because of a known relationship or association with a person with a disability.
- Administration methods: Using qualification standards, employment tests, or other selection criteria that screen out people with disabilities, unless the applicable statutory conditions are met.
Section 12112 also addresses the operation of workplace facilities. A covered employer must not use standards, criteria, or methods of administration that discriminate on the basis of disability, nor deny a qualified person equal jobs or benefits because facilities are inaccessible or unusable. Accessibility duties may apply to physical spaces, workplace systems, and other aspects of employment.
Reasonable Accommodation and the Interactive Process
A reasonable accommodation is a change to the application process, work environment, or usual way a job is performed that enables a qualified person with a disability to apply for a job, perform essential functions, or enjoy equal employment benefits. The ADA does not require an employer to remove an essential function or lower a uniformly applied production standard.
Possible accommodations vary by job and individual. Examples may include accessible equipment or facilities, modified schedules, reassignment to a vacant position, changes to training materials, a qualified reader or interpreter, or adjustments to how a task is performed. These are examples, not guaranteed solutions; an accommodation must be effective and reasonable in the specific circumstances.
An employee or applicant generally needs to let the employer know that an adjustment is needed for a reason related to a medical condition. The request does not have to use the words “ADA” or “reasonable accommodation.” When the need or an effective option is unclear, the employer and individual may exchange information to identify a workable accommodation. The EEOC commonly describes this as an interactive process, although the statute’s central requirement is to provide reasonable accommodation unless doing so would cause undue hardship.
An employer may choose among effective accommodations. It generally does not have to provide the employee’s preferred option if another effective accommodation is available. Reassignment may be considered as an accommodation when an employee cannot perform the current job’s essential functions, but the statute does not require promotion or creating a new position.
Undue Hardship and Safety Rules
An employer may decline a particular accommodation if it would impose an undue hardship. Under 42 U.S.C. § 12111(10), that means significant difficulty or expense, considered in light of factors such as the accommodation’s cost, the employer’s financial resources and size, the facility’s resources, and the effect on operations. A generalized claim that an accommodation is inconvenient or expensive is not, by itself, the statutory test.
Employers may also apply legitimate safety requirements. The ADA permits a qualification standard that excludes a person who poses a direct threat—a significant risk of substantial harm to the health or safety of that person or others—that cannot be eliminated or reduced through reasonable accommodation. The assessment must be individualized and based on objective evidence, not assumptions or stereotypes about a diagnosis.
Medical Questions, Examinations, and Confidentiality
Section 12112(d) places limits on disability-related questions and medical examinations. Before a conditional job offer, an employer generally may not ask an applicant whether they have a disability or ask questions likely to reveal one. It may ask whether the applicant can perform job-related functions, with or without reasonable accommodation, and may ask about qualifications relevant to the position.
After a conditional offer, an employer may conduct a medical examination or make disability-related inquiries if it does so for all entering employees in the same job category. For current employees, medical inquiries or examinations generally must be job-related and consistent with business necessity. The statute also permits certain voluntary wellness-program inquiries and examinations within applicable legal limits.
Medical information obtained under the ADA generally must be kept confidential and stored separately from ordinary personnel records. The law allows limited disclosures, including to supervisors and managers who need to know about restrictions or accommodations, to first-aid and safety personnel when appropriate, and to officials investigating ADA compliance. Applicable privacy and employment rules may add further requirements.
How to Raise a Workplace Disability Concern
Employees and applicants who believe an employer has violated the ADA can document the relevant events and consider making a clear written request for accommodation, where appropriate. Useful records may include job requirements, accommodation communications, relevant policies, performance reviews, and the dates and reasons given for employment decisions. Medical information should be shared only as needed to explain a limitation or support a request.
Many private-sector and state or local government Title I claims begin with a charge filed with the U.S. Equal Employment Opportunity Commission (EEOC). The filing deadline is generally 180 days from the alleged discriminatory act, but it may extend to 300 days where a state or local agency enforces a law prohibiting the same type of discrimination. Deadlines and procedures can depend on location and claim type, so waiting can put a claim at risk. The EEOC provides information on filing and charge processing at eeoc.gov/filing-charge-discrimination.
Federal employees and job applicants generally must contact an agency equal employment opportunity counselor within 45 days of the matter at issue, subject to limited exceptions. Their procedures differ from the standard EEOC charge process. A person considering a claim may wish to consult an employment attorney or a legal-aid organization about deadlines, evidence, and available options.
Potential Remedies and Related Protections
Depending on the claim and circumstances, remedies may include hiring, reinstatement, promotion, back pay, front pay, reasonable accommodation, and other equitable relief. Compensatory and punitive damages may be available in certain intentional-discrimination cases, subject to statutory rules and limits. Under 42 U.S.C. § 1981a, the combined cap on compensatory and punitive damages varies with employer size, from $50,000 for employers with 15–100 employees to $300,000 for employers with more than 500 employees. These caps do not apply in the same way to back pay and other equitable relief.
The ADA also separately prohibits retaliation and interference under 42 U.S.C. § 12203. It protects people who oppose unlawful practices, participate in ADA proceedings, or exercise rights under the law from specified retaliatory conduct. Retaliation is a separate legal issue from whether the original discrimination claim succeeds.
These provisions describe general federal law, not a determination of any individual claim. The governing facts, court decisions, agency rules, and state or local protections can affect how 42 U.S.C. § 12112 applies in a particular workplace.
