Answer:
The Act that protects disabled employees from discrimination at work is the Americans with Disabilities Act of 1990.
Step-by-step explanation:
The Americans with Disabilities Act (ADA) protects: physically disabled employees, e.g. use a wheelchair or have Down Syndrome. It also protects employees against discrimination based on past disabilities, e.g. employee that had cancer and was cured.
The Vocational Rehabilitation Act of 1973 included some parts that protected disabled employees but those parts were replaced by ADA in 1990, and now it focuses on sick employees, e.g. HIV positive, and not disabled employees.
