This is the Impact Assessment for applying a time limit to people's eligibility for Employment Support Allowance.

http://www.dwp.gov.uk/docs/esa-time-limit-wr2011-ia-revised-apr2011.pdf

I see a problem with "To ensure that ESA is paid for a temporary period thereby creating a culture that does not allow people to stay permanently in the WRAG, that they are expected to move towards work or into the Support Group if there is deterioration in their functional impairment."

What about someone that has a static impairment (and I'm assuming was initially correctly placed in the Work Related Activity Group) , so won't be eligible for the Support group as their impairment isn't severe enough, but needs support to find work, and doesn't find work in the allotted 12 months? Are they considered miraculously no longer in need of support?
