It's always looked a really odd campaign to me. As far as I can see, the oldest women affected when it changed in 1995, 44 at the time, and that group would have expected to retire at 60, but would now retire at 61.
Anyone losing the full five years would have been 40 or under. It's hard to believe that something so momentous passed anyone by for around two decades.
The 2011 changes brought the move to 65 forward by 2 years, to 2018, but the group affected were contacted directly to let them know it was happening, and would have had 7 years notice of a 1 year change.
I also, never understood the poverty situation if people were having to retire later. Is the argument that they gave up work at 60 without realising the pension wouldn't come?
Am I missing something obvious?
