Some people work from 8 to 5 but do not have a lot of a break in between. Perhaps an hour to an hour and a half in total or even less than an hour.
Even in middle and high schools, or secundary education if youre from the uk, youd get 2* 50 min lesson a 15 min break, 2 more 50 min lesson, 30 min break and then more till your school is out.
If youre lucky on a school with a slightly different schedule you might get 15-30-15 which isnt really much at all if you have a long day. (like times mentioned before).
Also in another place there was no privacy during breaks either. You were expected to eat together. Which means you cant really go and meditate in between. Now school is a bit different but workplaces are not ideal.
And you are also expected to give it your all every second of every minute that you are on your feet at work.
Its tiring. And the lack of proper nutritious food doesnt help either along with the overdose of coffee which everyone has to take every single day to function enough only to then collaps becauee of energy run down. So they take another coffee.
And the circle continues.
8 to 5 is 9 hours of labor a day. 5 days a week would be about 45 hours of work that youd have done.
It seems your day schedules are worse but how much of it is rest?
How much time do you sit and eat or sit and drink coffee?
That is something that is important too.
Take the rest into consideration as well.
