Mr. David Moloney:

The 2011 policy replaces an earlier policy which would, in the main, have given one ten years added service and put one into pension payment immediately. The 2011 policy was created in the context that people were not happy that people before preserved retirement age were immediately put into significant pensions. The policy decision was taken that instead of giving added years, alternative posts would be offered up to pension age. That is why it might appear to be more frequent; this policy is only in place since 2011.
