It's not ghettoising though is it smallwhitecat, it's giving people opportunities to do things if they so choose that they would not have had a chance to do otherwise, like working. Obviously the preference is for everyone to work together, with working conditions reflecting their ability.
Put it this way, have you ever had any concessions made for you during pregnancy for example? I know I have, but then I do a very physical job and wasn't able to do those parts of my job for a while. I'm very grateful my employer was good enough to adapt the job to suit my situation, albeit temporarily.
Remploy have provided people who would otherwise fail to get a job on the open market with employment. It's not ghettoisation, it's providing realistic solutions.
Not having any experience of disabilities, I never know if I sound really patronising saying the above. I mean, who am I to know? It makes sense to me whenever discussing abilities or otherwise in many contexts - education, employment etc - that it makes sense to adapt conditions to help people work better with their disabilities. If you extrapolate the argument further, the logical conclusion would be to get rid of all schools that exclusively teach disabled children. And surely that's wrong too? Not all children can be taught in mainstream schools and really need extra help. Isn't the same true for those who want to work?
Or am I missing the point totally?
