Then the department where he worked was disbanded and everybody was laid off. All his coworkers got unemployment benefits, but he couldn't, because he was disabled. So he had to get disability instead. So he applied, and was told that this wasn't a new disability, so he had to apply for something for inborn disabilities, which was a slightly different agency. So he did, and was told that that was only for people who have never been able to work, and since he had had a job, it didn't apply to him.
Personally I think everybody who manages to work and make money despite their disability, should just be able to keep everything without losing their disability pay. We should be rewarding them, but instead we're punishing them.
