The Americans with Disabilities Act prohibits discrimination on the basis of disability in employment, public accommodations, transportation, communication, and services provided by state and local government. Title I of the ADA addresses employment discrimination against people with disabilities. Among other things, the ADA prohibits an employer from rejecting an applicant solely because of the need to provide that applicant with a reasonable accommodation. At the same time, the ADA requires that an employer maintain confidentiality about the applicant or employee's medical condition or medical history obtained during acceptable inquiries, including those inquiries needed to design appropriate accommodations.
