The ADA Covers More People Than Most Employers Realize

The Americans with Disabilities Act was signed into law in 1990, but its reach expanded dramatically when Congress passed the ADA Amendments Act of 2008 (ADAAA), effective January 1, 2009. The amendments were a direct response to two Supreme Court decisions — Sutton v. United Air Lines (1999) and Toyota Motor Manufacturing v. Williams (2002) — that courts had used to narrow the ADA's coverage so substantially that workers with cancer, diabetes, epilepsy, and HIV were being found not disabled enough to qualify for protection. The ADAAA reversed that trend, instructing courts to interpret "disability" broadly and to focus analysis on whether discrimination occurred, not on whether the claimant qualifies as disabled.

Three Paths to ADA Coverage

The ADA protects qualified individuals with a disability from discrimination in hiring, firing, pay, promotion, and all terms of employment. "Disability" is defined three ways:

  • Actual disability: A physical or mental impairment that substantially limits one or more major life activities (walking, seeing, hearing, breathing, concentrating, communicating, and dozens more recognized post-ADAAA)
  • Record of disability: A history or record of such an impairment — e.g., a cancer survivor who is now in remission
  • Regarded as disabled: The employer takes a prohibited action based on an actual or perceived impairment, even one that is not substantially limiting

The "regarded as" prong, significantly strengthened by ADAAA, does not entitle the individual to reasonable accommodation — only protection from discrimination. A job applicant rejected because the employer mistakenly believed they had a communicable disease has a "regarded as" ADA claim, but cannot demand an accommodation on that basis.

Coverage TypeAccommodation RightsADAAA Change
Actual disabilityFull accommodation rightsMitigating measures (medication, prosthetics) ignored when assessing limitation
Record of disabilityFull accommodation rightsClarified to include conditions that are episodic or in remission
Regarded as disabledNo accommodation rightsLowered bar — employer only needs to perceive an impairment, not a substantially limiting one

The Interactive Process Requirement

When an employee requests an accommodation — or when the employer knows a disability may be affecting performance — the law requires both parties to engage in an "interactive process." No script is required. The interactive process is a good-faith dialogue to identify the employee's limitations, explore potential accommodations, and evaluate whether proposed accommodations are effective and feasible.

Employers cannot skip it. Courts have held that an employer who ignores an accommodation request or refuses to engage in the interactive process may be liable for ADA violations even if a reasonable accommodation would have been available. The burden-shifting framework:

  • Employee requests accommodation or limitation becomes apparent
  • Employer must respond in good faith and seek information from the employee
  • Medical documentation supporting the limitation may be requested if the disability is not obvious
  • Employer proposes accommodation; employee can counter-propose alternatives
  • Final decision rests with employer, but must choose an effective option if one exists

Reasonable Accommodation in Practice

Reasonable accommodations modify the work environment or how a job is done. The word "reasonable" does not mean minimal — courts look at whether the accommodation enables the employee to perform the essential functions of the job. Common examples span a wide range:

Accommodation TypeExampleNotes
Schedule modificationFlexible start time for employee with multiple sclerosis experiencing morning fatigueMust not eliminate essential attendance requirements
Remote workTelecommuting for employee with mobility impairmentPost-COVID courts increasingly view as viable; depends on job duties
Equipment/technologyScreen reader for visually impaired employee; ergonomic workstationEmployer bears the cost
Leave of absenceExtended leave beyond FMLA entitlement as ADA accommodationMust have definite return date; indefinite leave rarely required
Job restructuringReassigning marginal (non-essential) functions to another employeeCannot eliminate essential functions entirely
ReassignmentTransfer to vacant position the employee is qualified forLast resort; employer not required to bump another employee

The Undue Hardship Standard

Employers need not provide an accommodation that causes "undue hardship" — significant difficulty or expense given the employer's resources, nature of operations, and other factors. Undue hardship is a high bar. A Fortune 500 company claiming financial hardship for a $500 accommodation will not prevail. Relevant factors include:

  • Cost of the accommodation and the employer's financial resources
  • The number of employees and the size of the facility
  • The nature of the business and its operations
  • The impact on the facility's operations and other employees

The EEOC considers tax credits and deductions available to employers for accommodation costs. Small employers face a lower threshold for undue hardship than large corporations.

The Direct Threat Defense

An employer may refuse to hire or may remove an employee who poses a "direct threat" to the health or safety of themselves or others — but only if the threat cannot be eliminated or reduced to acceptable levels by reasonable accommodation. The Supreme Court's decision in Chevron U.S.A. Inc. v. Echazabal (2002) confirmed that a direct threat to the employee's own health counts, not just threats to others.

Courts require the direct threat assessment to be:

  • Based on individualized assessment, not generalizations about a condition
  • Based on the most current medical knowledge and the best available objective evidence
  • Considering the imminence, duration, likelihood, and severity of potential harm
  • Not based on unfounded fear, employer discomfort, or stereotypes about disability
