You made the right decision all those years ago, Neil.
Meanwhile, I wouldn't worry too much about our brothers (and sisters) working for the largest employer in Western Europe. Many are (and have always been) paid far in excess of their true worth anyway.
And don't forget, they have job security and a pension at the end of it. Those who are "dissatisfied" with their Pay Banding should be grateful for all that, I would have thought. That is, be thankful they have a job (and a comfortable job, at that).
It's a matter of horses for courses (as I say), and I have no problem with that. But although some may bitch and moan about the "threat" (real or imagined ... and mostly the latter) from private contractors, most NHS techs would not last a month out there (here) in the cold. And it is
a bit cold today.
