We have a problem in some companies whereby, as you mentioned, Conductor, Parkies get fired from their jobs or at least get tested endlessly;' they are not judged on their ability to do the job, they are judged on some childish and dubious neuro tests.
Some PWP are working to have witnesses when that day comes. Genevieve baked cakes and took them to all her neighbours; told them she has PD but did not dwell on it. Now the neighbours say hello; she has a better chance of survival as her condition worsens. She has revealed herself to people around her, starting by her helping them.
JimmyBear went into town and raised money.... for cancer.
A few got together and went to a town hall meeting, just to discuss what everybody else was discussing. With walkers, slurred speech, trembling hands. Talking about the budget for repairs to the old library. Everybody could see the symptoms, but that's not what the PWP talked about.
So there are witnesses in the local community who know that we have PD and also they witness to what extend we are still functional.
We had a guy, Eric, fired from his job at the first diagnosis, when nobody could even detect the symptoms - Eric was doing his job perfectly. Well, amazing event - people in town helped Eric get another job, and fired off nasty letters to the boss who had fired the PWP. They had all seen Eric around and figured he was competent and got a raw deal. PWP worked together to get Eric's story out and into the town, but it was average everyday citizens who stepped in to help out. (In the '60's we called that "co-opting the straights".)
