The benefit Tara Flood is talking is Disability Living Allowance, an in-work benefit. It helps defray the extra costs incurred by being disabled.
She may well be working. But need to pay for equipment or people to allow her to do her job. She may also need assistance at home for basic stuff like washing, preparing food, etc. She can swim but she probably can't wipe her own arse, for example.
And one of the big problems with the new assessment is that the intention is to reassess everyone, and keep reassessing them. In this case, they will discover that her arms haven't grown back. Each and every time. And ATOS will pocket taxpayers money, each and every time.
For people whose conditions are similarly permanent but who struggle with constant pain and exhaustion, whose conditions are exacerbated by stress, the cost of each ATOS assessment will be to their health as well as to the taxpayer.
There is a winner here, but it ain't the disabled and it ain't taxpayer...
