I used to go to work, do my job, then go home - and I enjoyed my office work far more pre computer days. In later years it was all, as you said, a minefield of wellness training, target setting, restrictions, appraisals, new concepts all the time that are a flash in the pan to show off some new manager's 'innovative ideas'. Those 'innovative ideas' rarely came with consultation with those actually doing the job, with the consequence that things didn't run smoothly, and required a lot of extra work - from those at the coal face of course, not management - before the problems were ironed out. And don't start me on meetings - so many, many, meetings,
THIS! ^ If I could 'like' this post 100X I would!! (AND @Churchview 's too that you quoted.)
I reckon most people over 50 can identify with this post. It certainly resonates with me. Many jobs - post year-2000 - became such a fecking ball-ache most of the time. And yeah appraisals are shit. What narks me off is 'how can you improve yourself,' and 'what out of 5 do you give yourself for a, b, c, d, e, etc...' I can't say 'I don't need to improve' and 'I give myself 5 out of 5 for a, b, and c,' because they say 'there is no room for improvement if you mark yourself too high!' I think 'yeah? And?' 
Then there's the fact that pre mid 1990s, you would have a filing clerk, a typist, a receptionist, a wages clerk, and a P.A. (5 positions/5 jobs...) NOW one person is expected to do all 5 jobs! In the noughties, I went from 4 days a week to 3, and yet still did the same amount of work - but had 25% less pay. I also kept getting more and more work piled on me.
And these days, very few unskilled labour jobs offer decent contracts. Many offer just 8 hours a week contracts. They will have you in 20, 25, 30 hours some weeks, but then when there is a quiet period (like the 2-3 months following Christmas,) you will just be given your 8 hours some weeks. THAT doesn't pay the bills! 40+ years ago, people would have come out on strike for this shit!
And YES to every new fucking manager wanting to change everything and stamp their mark on it. My friend's DH has been doing 4 on 4 off nights - 10pm-6am since 2008. Suits him down to the ground. Just him on the shift. Another guy is his 'opposite.' They are both around 50.
Last year, this 23 year old bloke came in as Manager. Told these 2 men they were going to be changing from doing the 10pm to 6am shift, to 12 midnight to 8am. No reason for it. Just wanted to stamp his foot down and show he was the boss! Both my friend's DH and the other chap told him to get to fuck. They said it would take them an hour to get home, in the rush hour (at 8am,) instead of 15 minutes! And upend their days as they wouldn't get in til 9am. (Instead of 6.15 am like they do now.) They told him he can do one basically.
They both refused, and they were helped by the fact that the people who worked 6am-2pm didn't want to change to 8am-4pm! And the 2pm-10pm people had no intention of changing from 4pm to midnight.... So it never happened. Cheeky arsehole just waltzed in and tried to change the shifts of a bunch of people twice his age and older, who had done these shifts for 15-16 years.
