How easy to say women should work full time until they are 66 or 67.
Yes if you're sitting behind a desk all day. Not if you're in one of many other manual jobs which are incredibly tiring.
People who were contracted out will see on their pension forecast that their years have been reduced by that number of years. You can click through from there to see how many years, and what the impact has been - it is often quite a lot.
As I said, but maybe wasn't clear enough, the money will have been added to your occupational pension, and you will probably be better off, but if you thought you would get a full state pension on top of the occupational one, you will be mistaken. Your SP will be significantly reduced unless you can afford to buy back the years, at a current cost of about £800 a year (slightly more, I think). You can pay in instalments, or wait until your pension is due, but the price rises every year.
