The Americans with Disabilities Act (ADA) as Amended by the ADA Amendments Act of 2008 (ADAAA): Disability Discrimination in Employment
The Americans with Disabilities Act of 1990  (ADA) is broad legislation designed to integrate people with disabilities into the mainstream of all aspects of society. The ADA is divided into five sections, called ”titles.“ Title I covers employment. Titles II, III, IV and V cover public services, public accommodations, telecommunications, and miscellaneous provisions.
The ADA's protection applies to _people with disabilities_. The ADA explicitly includes people with mental disabilities, including individuals with psychiatric impairments.
Title I of the ADA prohibits private employers with at least 15 employees, religious entities with at least 15 employees, state and local governments, employment agencies and labor unions from _discriminating_ against _qualified individuals with disabilities_ in job application procedures, hiring, firing, advancement, compensation, job training, and other terms, conditions, and privileges of employment. Federal sector employees are covered by the Rehabilitation Act , which has been amended to parallel the ADA.
To _discriminate on the basis of disability_ means to treat a person with a disability differently and adversely from other people who do not have a disability. A _qualified employee or applicant with a disability_ is an individual who, with or without _reasonable accommodation_, can perform the essential functions of the job in question.
Congress passed the Americans with Disabilities Amendments Act of 2008 (ADAAA)  specifically to overturn a series of Supreme Court decisions that made it difficult to prove an impairment is a “disability.” The ADAAA made significant changes to the definition of “disability” so that the ADA’s protection should now apply to a much larger number of people.
Under the ADA, a _person with a disability_:
1. Has a physical or mental impairment that _substantially limits_ one or more _major life activities_; _or_
2. Has a record of such an impairment; _or_
3. Is regarded as having such an impairment.
The ADAAA did not define “substantially limits” but it did specifically reject the Supreme Court’s rigid and limited definition. A better understanding of “substantially limits” will emerge over time.
The ADAAA greatly broadened the definition of “major life activities” to include “major bodily functions.” As of January 01, 2009, these definitions apply:
_Major life activities_ include, but are not limited to, use of the five senses, caring for oneself, interaction with others, performing manual tasks, seeing, hearing, eating, sleeping, walking, standing, lifting, bending, speaking, breathing, learning, reading, concentrating, thinking, communicating, and working.
_Major Bodily Functions_ include, but are not limited to, functions of the immune system, normal cell growth, digestive, bowel, bladder, neurological, brain, respiratory, circulatory, endocrine, and reproductive functions.
The ADAAA redefines and expands coverage under the “regarded as” prong of the definition of “disability.” To satisfy the “regarded as” standard an individual need only show that he or she was subjected to an action prohibited under the statute (e.g., termination; failure to hire) _because of_ an actual or perceived impairment. It is no longer necessary that the impairment be perceived by the employer to limit or “substantially limit” a major life activity.
Before the ADAAA, “mitigation measures” that increase the functioning of a person with an impairment were considered in determining whether a person met the definition of “person with a disability.” In other words, the determination of whether a person was substantially limited was made after the person received the benefit of the mitigating measure. For example, if a person with diabetes controlled his or her diabetes with Insulin, that person may not have been considered as having an impairment, because the Insulin removed the limitations which were present before the medication.
Now, after the ADAAA, the determination must be made regardless of the mitigating measures; that is, before those measures are used or applied.
_Additional protections of the ADA_
Under the ADA it is unlawful to retaliate against an individual for opposing disability discrimination in employment, or for filing a discrimination charge, testifying, or participating in any way in an investigation, proceeding, or litigation under the ADA.
The ADA also protects other individuals in certain circumstances, including family members who are associated with a person with a disability.
Importantly, the ADA requires covered employers to make _reasonable accommodation_ to the known physical or mental limitations of qualified individuals with disabilities, unless it results in _undue hardship_. _Undue hardship_ is defined as something requiring significant difficulty or expense with respect to the employer's size, financial resources, and the nature of its operations.
_Reasonable accommodation_ may include making existing facilities readily accessible; job restructuring; modifying work schedules; reassignment to a vacant position; acquiring or modifying equipment or devices; adjusting or modifying examinations, training materials, or policies; providing qualified readers or interpreters; and more.
The ADA also requires covered employers to provide qualified individuals with disabilities with equal access to all employment-related opportunities. This includes medical insurance, social activities, vending machines, rest rooms, and more.
In addition, the ADA limits the disability-related questions an employer can ask a job applicant before a job offer is made. Employers may not ask about the existence, nature, or severity of a disability, but can ask applicants about their ability to perform specific 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 similar jobs. Medical examinations of current employees must be job related and consistent with the employer's business needs.
Although an employer may not discriminate on the basis of disability, if an applicant or employee poses a direct threat to the health or safety of him or herself, or of others, an employer may treat that individual differently _due to the direct threat_. An employer’s _direct threat_ defense requires proof there is significant risk of substantial harm which cannot be reduced or eliminated by reasonable accommodation. An employer’s stereotyped assumption that people with disabilities are more prone to harm is not an excuse for discrimination.
To pursue a case under the ADA, a person must file a claim with the U. S. Equal Employment Opportunity Commission (EEOC) within 180 days of the date of discrimination or failure to accommodate, or within 300 days if in a state with a fair employment practices agency. A person cannot file a lawsuit until the EEOC has had the opportunity to investigate and resolve the claim, and issues a right-to-sue letter.
Claims of disability discrimination in employment may be filed at any EEOC field office. For the appropriate EEOC field office, call the EEOC at (800) 669-4000 (voice) or (800) 669-6820 (TTY).
Many states have laws that are similar to the ADA or are more favorable to people with disabilities. California and some other states provide more generous remedies, a longer time to file the claim, easier procedures, and more.
