Well said Dicky.
The whole process went wrong when they released the pay spines for each banding. As soon as this happened, every man and his dog tried to beef up there JD's to try and reach parity with their current renumeration. I saw people selling their soul's down the river. By definition, the JD's almost became personal 'dream' CV's. Now they have matched bands to existing salaries, the trusts could call peoples bluffs by trying to ensure the individuals concerned do what is in the hammed up JD's.
Watch this space.
