Mrz,
I have a pension very similar to yours - because, like you, I was working during the period of defined benefit (final salary) pension schemes. My husband, sadly, although he worked through this period has always worked in companies with defined contribution (money purchase) schemes
The point I have repeated several times is that the way pensions in the private sector work HAS CHANGED since you and I worked there. People of my age who remain in the same company will have a proportion of their pension as defined benefit, and from the date that closed (my company's closed about 4 years ago) will have a defined contribution portion. So yes, I have simplified my point - people whose working lives have spanned both types of scheme will have a fixed and a 'purchase annuity' part of their pensions. Is that clearer?
Anyone who joins a private company now, or who moves jobs into a new private company, with a vanishingly small number of exceptions, will join a defined contribution pension scheme, with the amount of their pension unknown at the end of it.
The TPS remains a defined benefit scheme for everyone (from NQTs all the way up) even with the new proposals, with the amount of pension known at the end of it.
Where do you stand on the moral point about the luxury of striking over pensions at a time when many people are struggling to retain their jobs?
