The Americans with Disabilities Act (ADA) prohibits discrimination on the basis of disability in all employment practices. It is necessary to understand several important ADA definitions to know who is protected by the law and what constitutes illegal discrimination.  See the federal government’s website ADA.gov for general information on the ADA.

The Equal Employment Opportunity Commission (EEOC) has provided definitions under the ADA as follows:

• Individual with a Disability

An individual with a disability under the ADA is a person who has a physical or mental impairment that substantially limits one or more major life activities, has a record of such an impairment, or is regarded as having such an impairment. Major life activities are activities that an average person can perform with little or no difficulty such as walking, breathing, seeing, hearing, speaking, learning, and working.

• Qualified Individual with a Disability

A qualified employee or applicant with a disability is someone who satisfies skill, experience, education, and other job-related requirements of the position held or desired, and who, with or without reasonable accommodation, can perform the essential functions of that position.

• Reasonable Accommodation

Reasonable accommodation may include, but is not limited to, making existing facilities used by employees readily accessible to and usable by persons with disabilities; job restructuring; modification of work schedules; providing additional unpaid leave; reassignment to a vacant position; acquiring or modifying equipment or devices; adjusting or modifying examinations, training materials, or policies; and providing qualified readers or interpreters. Reasonable accommodation may be necessary to apply for a job, to perform job functions, or to enjoy the benefits and privileges of employment that are enjoyed by people without disabilities. An employer is not required to lower production standards to make an accommodation. An employer generally is not obligated to provide personal use items such as eyeglasses or hearing aids.

• Undue Hardship

An employer is required to make a reasonable accommodation to a qualified individual with a disability unless doing so would impose an undue hardship on the operation of the employer's business. Undue hardship means an action that requires significant difficulty or expense when considered in relation to factors such as a business' size, financial resources, and the nature and structure of its operation.

• Prohibited Inquiries and Examinations

Before making an offer of employment, an employer may not ask job applicants about the existence, nature, or severity of a disability. Applicants may be asked about their ability to perform job functions. A job offer may be conditioned on the results of a medical examination, but only if the examination is required for all entering employees in the same job category. Medical examinations of employees must be job-related and consistent with business necessity.
