These were first discussed and planned for implementation back in the 1990s. I was aware because at the time I was getting phone calls from private pension companies trying to get me to sign up, and then lose interest when they found out how old I was!
I do remember it being in the newspapers, and again later when the rate at which it was to be implement speeded up. (Early 2000s?)
So the info was out there but very haphazard. ie any of the Governments during that time could have made sure all employers sent out infor with pay packets or whatever. And equally private pensions schemes should surely have made their customers aware.
And in fact the DWP or whatever it was then could easily have sent out letters directly to those concerned. And/or local MPs or councils.
So I was aware of it, but can easily see how others might not. If you weren't at work, or weren't scanning newspapers for small bits of info it could be missed.
So if you had planned retirement based on some final pension payout it could have been a bit of a shock - to put it mildly.
Not forgetting that if it also meant you had left your job the prospects of a woman in her 60s getting a new job is not going to be good.
And as mentioned above more likely than a man to not have a consisted history of paying NI because of taking time of for maternity and childcare.
Also if you are then put in the position of having no work but still being too young to get your pension, if you have got "assets" ie a pension pot of whatever size, the amount of benefits you can claim will be reduced.
And for some it has probably comes as a shock to find out how little the Government think someone needs to survive for week, ie not just food, but service bills, and so on. Around £75pw. And if you have a partner who still has an income even less.
