inhibernation - moving away from London may not be an option you want to follow, but it's an option that many people in the private sector have had to take.
From what I understand, recruitment is an issue in areas such as London (and other expensive areas), and certainly cost of living is a problem. This is why I said up-thread that I think the Unions are focused on the wrong thing. They should be focused on salaries and funding into public services, not pensions.
As the risk of opening up the debate again, final salary pensions are unsustainable in this economy. What little money there is would be better spent on ensuring public sector workers are paid an appropriate salary for the work they do relative to the cost of living for the geographic location and to generally fund healthcare, education, social support etc, rather than focusing funding on a proportion of the population's pensions. That way it is an investment for everyone's future healthcare and education, and not just ensuring part of the population have a comfy retirement; the public sector may then get less than they expect in their pension, but the healthcare and social support would be bloody good (not that it's bad currently) and readily available, when and where it is needed; ie the pension may be less, but one aspect of a pensioner's cost of living would be lower.
I can't supply figures, stats or anything else to back this up, it's just a gut feel. And yes, I'm aware that some areas of public sector are paid more than private, so clearly these are not the areas I'm talking about.
There is a lot of mis-spend and poor management in the public sector (as in many private companies). I'm not pointing figures at individuals here; I'm talking about the system, the overly-bureaucratic processes and a culture that stifles effective change. I see the Unions as an example of this - hell bent on demanding their pensions, but not focusing on the issues that I believe are more relevant and more likely to have gained wider acceptance across the board.
