I've been whistleblower before, @DoctorDonnaNoble it did no good what so ever. I've learnt whistleblowers are not in any way protected, not that it mattered to me, particularly, as I had another job lined up, but if I hadn't I would have been left unable to pay my mortgage. I've seen it happen to others.
I have been morally complicit in some schools, but not in others. I have stuck to the law and suffered for it, but in the end decided its not worth it. I'm changing schools again now, and have decided to stick to the law again in my next school, because honestly, i am an education professional, so it really seems pointless not to. I don't know how long I will last though!
I did actually raise the possibility of reporting something in an exam room just a few weeks ago, but the invigilators were split. Two agreed to, two said they would deny it. In the end, reporting it would have harmed a lot of children who had tried very hard, and I didn't go ahead.
Its odd that you pick out the invigilation thread, where as far as I remember, nothing I said on there was procedurally incorrect. Plenty of lying and cheating described in other threads though!
What do you men by "doing harm"? I am telling the truth. What is harmful about that? People should know what is going on, don't you think. Corruption is devastating to our whole way of life, integrity and culture. it needs stamping out. People need to understand the league tables and education system for what they actually are.
