Final answer:
The Americans with Disabilities Act (ADA) prohibits discrimination in employment based on disability and requires employers to make reasonable accommodations for workers with disabilities.
Step-by-step explanation:
The Americans with Disabilities Act (ADA) is important for licensees to understand because it prohibits discrimination in employment based on disability and requires employers to make reasonable accommodations for workers with disabilities. This means that licensees need to be aware of their responsibilities in providing accessible services and facilities for disabled customers or employees. For example, licensees may need to install ramps, provide braille instructions, or make other modifications to ensure that their premises are accessible.
