There will be alot more to come when they have finished with the redundancies fiasco. Many are waiting to see if they can go with the additional cash buffer and are busy organising their lives to go. If that option isn't available, then they will go anyway.
I remember back in the 80s when Thatcher had to give us a 15% pay rise to retain/recruit. I can see that coming again in the nest few years when they realise what they have done to the forces morale and desire to stay in the job.
