I think I have got a happy medium going on at the moment. Although, I can't profess to having worked my arse off since I was 16. I do feel like I have "worked hard" though because before DC I worked 6 days a week and travelled a lot for work, and then when I was a SAHM I was alone most of the time as DH travelled 2 out of 4 weeks. I have also had to move countries 4 times to keep up with him, leaving behind jobs and friends.
4 years ago, when I moved back to the UK, I transitioned from SAHM to 2 days a week, and now I work 3 days (25) hours, and very unsociable hours. As my DC get older, people are asking me when I am going FT, but I don't want to. I am 54, work P/T and the rest of it I do what I like; gym, hobby, running club, dog walks, meet friends for coffee, look after myself and of course all the household chores (in that order!)
I have a good balance. I have some money coming in, the house is in order, my DC are sorted, I have the self esteem of working, my state pension is being sorted, and I have good mental health.
Having experienced other countries workplaces and cultures I can see first hand that the UK is just a big washing machine of stress. Commute, work, commute, bills, tax, no time to relax, little time to exercise, poor social connections, poor nutrition, poor healthcare. A lot of us will be lucky to retire TBH if we don't drop dead first.
I don't care what the Tories think about over 50's refusing to kill themselves working. It is of their own making. The greed in this country is breathtaking. I'm talking the people at the top, not the average guy. It's time to push back and say NO.
