Absolutely. I work 8-6 most days although there is no set time (sometimes I'll start at 10, sometimes end at 4 and sometimes work 18hrs a day just to get things done).
Even if you worked workd exactly 8hrs a day that is a third of you time, you have to add on commuting, and sleep, and just doing house work/chores/paying bills/getting car repaired etc). End of the day it leaves very little time left. And getting an odd hour here or there each evening to yourself, although nice, is not useful. E.g. I want to go skiing everyday so would love a 5hr window in winter to do that, 1-2hrs is basically just right to have a beer and watch a little TV.
And then there is the fact that if you work your 8-10hrs at the end of it youre too tired to do much in the evening. And if you are in any job with any kind of responsibility then you also end of thinking and stressing at the weekends. You never really get a break.
On the flip side it is hard to do a thing. You need money to live. It is also not easy for most people to reduce working hours. I would love to work 4 days a week but the overheads for staff are such that this is a very expensive proposition for most companies. Plus is tends to break scaling and time tabling, e.g. I would in a 6 man team and it is a race against time to get our product out before competitors. If half the team workd a 4 day week then timetables would slip and the bussiness be less viable, so then we would need an extra hire which increases running costs further.
So my plan is early retirement. I hope to retire from the long hours and stressful but high paying career by my late 40s early 50s. I need to earn as much has I can in the next 15-20 years, pay of the mortgage, get pension up to speed and some investments, and then retire to a part time casual job that pays beer money. I'll possibly end up being an old ski bum, doing odd jobs in ski towns and skiing as much as I can. I'm kind of doing life in reverse to what a lot,of people do. But if you are in a job that pays well then there are a lot of benefits to sucking it up and making a decent living.
Still, if an employer offered me a 3 or 4 day week I would liekly take it up and postpone retirement.
I'm very thankful to be in a position to earn £50-80k a year.
