Twenty-nine years ago, it was fine for your potential employer to ask if you had ever had back surgery, had filed a workers’ compensation claim, or had recently spent time in the hospital.If you were a wheelchair user and had business at the upstairs county courthouse, you had two choices: ask the guards to carry you up or drag yourself up on your stomach.And since there was also no requirement that sidewalks have curb cuts, you had to take your chances when you rolled yourself down the sidewalk and then hoped to get yourself and your wheelchair safely onto the street.This sad landscape changed forever in 1990, when the Americans with Disabilities Act (ADA) was passed. As discussed elsewhere in this website, the ADA requires non-discrimination and reasonable accommodation in areas like employment, state and local government and most private businesses that are open to the public.Of course, there are still massive violations of the ADA everywhere you look. The difference, however, is that there now is some legal apparatus to turn to for redress. And the more people do that, the more that things like elevators and curb cuts will become the norm.If you want some quick and thorough education about the ADA and other disability laws, go to https://adata.org. You will find a treasure trove of easy-to read explanations, as well as examples, recent court cases and even quizzes to test how much you have learned.And…it’s free!Happy Birthday, ADA!
