Divergent Perspectives: Can't is Not a Bad Word

So I am someone with ASD/ADHD and multiple chronic physical medical issues, fo me the workplace can be brutal. For many years I burned myself out trying to meet unreachable expectations all the while being told I could do things that I really couldn't. At some point I had to speak up and explain that there were some things that I couldn't do. It was very discouraging to see how difficult it is for a workplace to try to accommodate anything that doesn't meet their ideal. The companys themselves would probably have tried to accommodate the problems, but the managers and everyone in between, instead tends to push back in ways that are very problematic to actually making the needed changes for a workplace to be truly more accessible for different types of people.
