I retired officially at 55, thirteen years or so ago. (I was a midwife, it was allowed at the time. I think younger midwives/nurses must carry on for longer).
I had had enough, my health was suffering. Physically and mentally. Unsocial hours, long shifts, poor staffing levels, huge responsibility-it all add up. So it was my choice to retire. I was lucky to be able to.
But after a year or so I went back to work as a bank midwife, for two years (no shifts/no unsocial hours, working as much or as little as I wished). My choice again. The control over my hours made a great deal of difference. I was no longer leaving my bed in the early hours to spend hours working for a few pennies and maybe time off in lieu.
While I was working as a bank midwife, I saved that money, forcing myself to live on my NHS pension. It was doable. So, after the two years working on the bank, I stopped working and threw myself into other things. I was 57. Then I did several days childcare for grandchildren once theirs mum's mat leave finished. To date we have had some degree of child care for 9 years and counting. Currently we do school drop off's and pick ups, plus some school holidays.
My state pension kicked in at 66. I most certainly could not have gone back to work as a full-time, all singing, all dancing, unsocial hours working midwife. Thirty odd years were enough for me, and I suspect many others like me in the modern NHS.
If people such as me are to be enticed into the work force, consideration needs to be taken as to energy levels, less than optimum health, caring responsibilities etc. Not all employers are keen to employ a 60+ individual.
I despair for my children.
