Many disabled workers face disability discrimination at work. This kind of discrimination can appear in many ways, including failure of the employer to make reasonable accommodations for the disabled employee. The Americans with Disabilities Act (ADA) is a set of laws that was passed in 1990 to provide comprehensive protection of the rights of the disabled. The ADA sets guidelines for employers, one of which is the right of disabled employees to reasonable accommodation. A disabled employee has the right to request an accommodation, and the employee must put forth reasonable effort to meet the request. If the accommodation is impossible, the employer can relocate the employee in a vacant position within the company.
