Part of the problem is the way the DRC are funded. They have about enough money to take 50-60 cases a year so with that limit they have to pick and chose which cases they take on. It's a very poor way for disabled people of all flavours to get justice and a number of employers realise this. As an ex-DRC employee I know that most of the staff there would love to be able to do just that, sort out all the injustice that is being inflicted across the UK. It was wearing to have to 'defend' a situation that you personally disagreed with whenever you encountered people's (quite understandable) anger at the lack of ability to engage in more cases.
