I worked at York University before coming to this position, or at least on my road here. I saw students graduate side by side, people like Noel and me—a huge age difference here, but nevertheless—and I would graduate with a self-declared disability and Noel would graduate without one. Otherwise, we had the exact same degree, the exact same experience.
The barriers that young kids—recent grads with disabilities—face are higher, so really, it's about workplace accommodation. What we found is that once that workplace accommodation is made, it changes the cultures of organizations permanently. Again, going back to your first question on people with disabilities, assuming there is a match between the employee and the employer, the retention tends to be higher.
And your last question...?
