Final answer:
The statement from the options provided that is not true of the Americans with Disabilities Act (ADA) is that the ADA covers only qualified employees and not qualified applicants, as the ADA also protects qualified job applicants from discrimination.
Step-by-step explanation:
The statement which is not true of the Americans with Disabilities Act (ADA) is: D) The ADA covers only qualified employees and not qualified applicants who are able to perform the essential job functions. In reality, the ADA also protects qualified applicants from discrimination on the basis of disability during the hiring process. The ADA defines a disability as a physical or mental impairment that limits one or more major life activities, and an employer must make reasonable accommodations for qualified individuals with disabilities. This includes both applicants and employees.
The ADA does indeed not protect employees who currently use illegal drugs as per statement A). It requires reasonable accommodations as stated in B), and the Act considers drug and alcohol addiction as medical conditions when it comes to past addiction and recovery, thus statement C) is also true. Hence, only statement D) is not true regarding the ADA.
