All U.S. businesses are subject to The Americans with Disabilities Act (ADA). The act prohibits discriminating against people with disabilities, including the Deaf and hard-of-hearing. Companies with 15 or more employees must provide equal opportunity to apply for, interview for, and maintain a job. That includes supplying an ASL interpreter if a Deaf candidate or employee requests it. Businesses may enlist their own ASL interpreter staff or outsource through a reputable third-party, such as Sorenson.
