It won't make any difference.
These people really see themselves as victims.
Public sector workers, under threat of redundancy, internally bullied by senior staff who hide behind frontline workers and can't make a reasoned decision to save their lives (because their decisions are all about money and that's, er, not legal), they believe everyone is out to get something they are not entitled to or to get something they are entitled to in priority to others.
This is how they justify it to themselves - the lying, the lack of integrity and transparency, the hounding or villifying of parents - they are protectors of public funds. A small pot of money which has to be carefully distributed and guarded against middle class know-it-alls who want a 'rolls royce' education off the state.
I was told once in a meeting with a vile head of SEN that 'those who shout loudest don't get' which is, of course, total bollocks because those who don't shout don't get either, so who is 'getting' anything?
They should turn their anger on the lack of funding not us. They should be marching about that not their own pensions. They should get another job where they don't have to end up knee deep in deceit. They should whistle-blow about lying managers.
But they won't. They take their money and keep their mouths shut. So there is no point appealing to their better nature. They are beyond that. We have been dehumanised as far as they are concerned.
