Businesses have come to recognize the benefits of a diverse workforce. However, accessibility is often not integrated within the Inclusion, Diversity and Equity context, and is too often overlooked. The work of Hub 4 aims to understand how best to implement inclusion, diversity, equity, and accessibility (IDEA) in workplaces from inclusive and universal design perspectives. To achieve that goal, the Hub 4 team is working to assess IDEA activities across Fortune 100 companies through a website scan, validation survey, and focused interviews. Using a co-design process, the team is developing guidance on inclusive workplace practices and systems.
