eglnyt - you cant agree with anything can you!
I'll try to make it more obvious for you though - it is very likely that two people who have had careers identical in every respect except for a 'join' date, who have had the same salary for the last 20 years +, who at no point have had any differences to pensionable pay, could receive a different pension under this proposal even if they retire on the same day, and have accrued the maximum 2/3rds pension.
Its morally wrong - and it wouldnt be a defined benefit scheme. If you cant tell me what % of my final salary i will receive on retirement, you cannot call this a DB scheme any more.
ERIC, not biting on that one
