People who have health issues - whether physical or mental - can have others advocate on their behalf Yes... often the same people who are/were assessors, or even the 'job coach' who never seems to tell you what you need to know!
An anecdote, if you will: I am a fully functioning adult, left my job, set up my own business. I researched JSA and then the support for new businesses. I understood it all, knew what he correct timings were and what the various sign on options were.
Go tot eh Job Centre, went through 3 hours of extensive Q+A session and... because I answered "I will need some bookeeping packages, haven't used them before" I was sent on the IT course! Now... I had only just finished telling them exactly how IT literate I am (used to work in IT) but once that button is pressed, you have to go - or you get sanctioned! So off I went...
... the woman patrolling the room (she couldn't teach anyone as the list of things we had to do was about 5 things long, do A, do B etc) was an ex colleague... a real IT teacher... she fell about laughing t see me. Then reality hit, those tasks should have taken about 5 minutes for me to do. Half an hour later I finally got the machine to admit it really could send and email, and I could escape. Those machines were out of the ark, if they were your only experience of computing you wouldn't bother.
THEN... I signed on.. he asked me if I had been seeking work. I looked puzzled, no, I was setting up my own business, JSA for 6 months then NEA, as I was entitled to. No, no, no... you MUST look for work - or you will be sanctioned. That continued until, rather than be sanctioned, I signed off!
Later I signed back on again, to get the NEA, as you have to be on JSA to get the advice etc. Oh god! Another chocolate teapot was the NEA specialist! I complained, he continued to get it all wrong (despite the tick list he was working from he couldn't understand why I couldn't give him my business plan in week 1, it is there at week 3....) and threatened, yet again, to sanction me.
Thankfully I think others noticed how much trouble he was causing and his replacement was fully competent.
So... if I with degrees, research skills and a clear plan, had so much trouble getting the people who are supposed to support you to actually do a competent job how does someone who has no bloody idea get the right information?
The system is ludicrous. Even the motivated, pleasant, competent staff can't always help you though it as it is designed to put barriers in your way! We should ALL be ashamed of how our society treats the truly needy!
