if you have to work all three shifts every three weeks, you can't realistically hold-down a second job or attend regular classes, you're exclusively at the disposal of your masters.

Sounds like some dinosaur is operating these facilities thinking they're still in the time period where that was acceptable.

i like that you only have to work 2/4 weekends in a month. That's pretty cool.

How nice and thoughtful of them.

I am guessing these workers don’t have a union.

no, it's that they don't give a shit about those and have found a way to make more money, so they believe, no doubt on a paucity of evidence and a big kick of power madness.

You don't wanna see the schedule of a relative of mine that works as a hospital nurse then.
And she has the good version of the schedule.
You really don't wanna see the schedule of an emergency admission nurse.
Daily changing hours of various schedules switching between early and late with maybe the minimum or 2-3h more of break between shifts...

Wow, that's nuts. At least the manufacturing jobs I see around me are just 4on 4off 12hr shifts, which still sucks IMO, but isn't abusive to employee's mental well being.

The rotating to an earlier shift is even more insane. Maybe I'm wrong but I imagine almost everyone finds it easier to push through and stay up later than try to go to sleep 7 hours early.

We still got shift differential on swing shift. I did it for 7 years. It maximizes 24/7 coverage with less crews, but it has a side effect of the end users of the schedule developing severe alcohol abuse and depression.

Sat - Friday 8 hours day

Wednesday - Tuesday 8 hours night

Friday - Thursday 8 hours second

The pay period was separated in such a way that you would not get double time even though you are scheduled 7 days in a row every week.

I messed the schedule up so I fixed it. And yes, there was only 1 day off between second shift and day shift rotation.

Companies now want 24 hour productivity, which means they will abuse their workers to keep that cycle going. Worker healthy is probably not even a thought, just: how do we get more out of them?

I work some where that does double shift which is mornings one week and afternoons the next. It's OK but id prefer standard days, I have however done triple shift for a year at one job and it completely messed me up, and to this day I blame it for giving me super high blood pressure I didn't have before I started it. It all comes down to profits, why buy another machine to manufacture whatever it is you do when you could simply run the same machine 24/7. Although it inevitably leads to disaster one machine doing all the work as triple shifts leave little time for maintenance and seeing managers flap about because a machine broke down because you were allowed to shut it down to grease the bearings once a week is hilarious.

Possibly so they don't have to pay night shift more?

Too many billionaires

No one wants to work constant nights, but plants need to run constantly, so you get this bullshit.
