What is disability under ADA?
The ADA only applies to persons who meet the definition of “disabled” under the Act. A person is considered disabled, and so protected under the ADA, if he or she either actually has, or is thought to have, a physical or mental impairment that substantially limits what the ADA calls a “major life activity.” Major life activities include walking, talking, seeing, and learning. If an employee has impairment that substantially limits his or her ability to perform one or more of these activities, the employee is considered disabled under the ADA.
