Final answer:
The Americans with Disabilities Act (ADA) sets guidelines for companies working with individuals with disabilities and requires reasonable workplace accommodations, enforced by the U.S. Equal Opportunity Employment Commission.
Step-by-step explanation:
The organization that establishes guidelines for companies that work with individuals with disabilities is the Americans with Disabilities Act (ADA). The ADA is a law passed in 1990, which prohibits discrimination against those with disabilities and requires employers of more than fifteen people, as well as governmental organizations, to make reasonable accommodations for disabled persons in the workplace.
Entities like the U.S. Equal Opportunity Employment Commission enforce these regulations, and resources such as the Job Accommodation Network (JAN) provide guidance for employers on accommodating employees with disabilities.
