"and where blue collar workers get to retire on a full pension before white collar workers."
Yes, if only I could enjoy the life of a blue collar factor worker in China. Why can't I work 12 hour shifts 6 days a week?!
Good news - you can! Ex. get a job with the FDNY and you can easily work 4 back to back 18hr shifts and pick up overtime on your days off too!
Apologies in advance for the following off topic rant/tangent...
FYI, FDNY dispatchers work an abnormal schedule. It's so abnormal it's difficult to quickly describe it. The normal shift, without mandatory or voluntary overtime, looks something like this:
DAY: SHIFT
1: 7am - 7pm (12hr)
2: 7am - 7pm (12hr) ... 24hr between here ...
3: 7PM - 7am (12hr overnight into next day)
4. 7PM - 7am (12hr overnight into next day)
5. off, but they did just work until 7am, so does that count as a day off?
6. off
7. off
8. off ... cycle repeats ...
9: 7am - 7pm (12hr) ...
IE: 4 days on (2x 12hr day, 2x 12hr nights), 4 days off. That repeats 3 times before they get 5 days off, then it goes back to 3 of those with 4 days off between them.
And vacations? Those are pre-assigned and you don't get to pick them.
Sick time? Can't take more than a day without a doctors note.
Lunch breaks? None. Technically not even allowed to eat at their desks, but they obviously must or they'll literally starve.
And they're minimally staffed. If someone calls off, that has to be covered, often requiring mandatory overtime (in 6hr blocks). And due to their pension setup, many try to take excessive amounts of overtime whenever its available, the result of which should be no surprise - they sleep on the job, so their exhausted coworkers on "short" 12hr shifts have to cover for them.
If one has overtime on their first day (IE: 18hr shift), they have 6 hours between the end of that shift and the start of the next shift. They're also expected to come in early to relieve those on duty, and nearly everyone comes in early.
Lastly, their union keeps voting to keep this structure. My guess is some variant of stockholm syndrome runs rampant there. Labor laws have made this sort of practice illegal for ages, but there are exceptions for emergency services. Those exceptions are abused.
