"you assess them continuously wherever possible."
A-bloody-men
I'm lucky to to know anybody who suffered and much of that (certainly here) has to be down to those in charge and the fact that there are enough around with a bit of clout to tell them when they are nausing up without having to wait for the next election - the difference that a PR system and an openly critical popular press makes is almost palpable sometimes
Lessons to be learned maybe
