Increasing the PVR wait time (to 3 years for example) is a negative retention factor in itself and may encourage a catastrophic outflow at one time. There is only far that compulsion can be taken before the whole system falls to pieces.

Lots of people I know are biding their time and pensions are keeping them in for now - the theory has always been that those who have done 12-17yrs service generation will take our places when we get to the magical 16/22.
