I'm in the process of preparing a workshop on the Americans with Disabilities Act Amendments Act which, I assure you, is much more interesting than it sounds.
What is fun is to crawl into the reasoning behind the Act and the conflict between Congress and the U.S. Supreme Court (as well as lower courts), then translate what managers need to know into plain language. Fun but tricky because there are plenty of side roads to be avoided; ones that could lead to glazed expressions and points of no return.
Always in the back of my mind is the cynical guy who sits in the back of the room, folds his arms, and wonders, "Why should this matter to me?" If I can capture the interest of that guy, all else follows.
