This seems idiotic from the employer's perspective. You're limiting your pool of candidates a lot by requiring that their life can accomodate essentially 24 hours of possible shift time. Companies do shit like this and then complain "nobody wants to work anymore"
They also leave the milisecond they can which means the company constantly has to find replacements and retrain them. Lots of resources wasted just to abuse people rather than maximize profit by treating people better.
This is true. I once had a boss with an MBA. I am highly skilled, had a decade under my belt at the company. She once almost laid me off one year because her and another middle manager thought I didn't "fit with the team" any more.
Turns out I was just going through a divorce, was deeply depressed, and simply getting shit done and going home.
She knew but that MBA mentality just saw that I wasn't joining extra calls, putting in extra hours, volunteering to manage projects, etc. It wasn't even about department or company performance, we were in some of our best years ever. I discovered this years later after she was laid off, probably under similar circumstances. Fuck MBAs.
As long as "temporary" foreign worker programs exist, there isn't a shortage of labour as far as the elite are concerned.
A limited pool of local applicants is a benefit to them. Then they get to bring in foreigners who don't know the value of their work in a western country and don't know the laws that protect them, both labour laws and actual criminal laws.
People don't want to work 3rd shift - the rest of the world (your family, sports...) all work 1st shift. 2nd shift is only slightly better. It is probably better for your life to work 3rd shift for 1 week of every 3, than 3rd shift constantly - those other 2 weeks you can live semi-normal and thus have friends.
It still sucks, probably the best compromise.
As someone who was forced to do this for a couple months when I was in the Army, rotating shifts destroys your ability to get good sleep, its horrendous to actually experience. It took about 2 months before people started getting so sleep deprived that people started failing PT (physical training) tests and it took the brigade commander looking at our battalion and asking "wtf is going on over there?" and hearing what our battalion had done to our shift schedule and put a stop to it. He called over every single soldier who failed their PT test to hear our excuses, and when most of us were first time failures and we all had the exact same complaint, by the time he got to me, he was like "You've been on rotating shifts, unable to sleep, and were forced to take this test after a shift when you're completely exhausted like everyone else?" "yes sir" "ok, don't expect that shift rotation to last, I'll be talking to your battalion commander after this. Send in the next person." Dude was ready to just start ripping into us but changed his tune right quick after hearing about the fucked up shift schedule and lack of any common sense in the leadership's ability to plan properly. One of the few times where shit actually rolled uphill. Suffice it to say, before I even finished the drive back to my barracks, I was being called by my platoon sergeant that we'd have to a new schedule tomorrow and to just show up for swing shift like we normally would be on.
In the prison I worked at we would usually rotate shifts every 6 months, but our commander heard complaints about people being on day shift for so long at one time that they were getting burnt out dealing with 90% of the problem times with inmates, and instead of changing it to every 3 months, changed the rotation to every 2 days. Literally, 2 days on Day shift, 2 days on Swing shift, 2 days on Night shift, 1 day off, then back to days. And that last day was getting off shift at 6AM, doing PT until 8AM, Barracks Maintenance until 10 AM, then because of the rotation, we'd have to be back in at work at 5:30 AM the next day, so our 1 day off a week was only 19.5 hours, and you're exhausted but you can't sleep yet, otherwise you'll be up all night before work the next day, so you force yourself to run on fumes, getting a haircut, getting food and supplies for the next week, etc. Then sleeping, so there was literally never any time to relax. It fucking sucked.
It's the kind of thing that sounds "fair" to a executive who's been trained to think about human resources like any other commoditized cog, with no concept of human physiology or empathy.
those other 2 weeks you can live semi-normal and thus have friends.
I don't think you're thinking about how hard this will absolutely fuck over your sleep. There is no way you can be a functional human being for those two weeks with this consistent and drastic of a schedule change.
It also makes it harder for employees to do things that would give them a chance at getting a better job. Can't go to college anywhere that requires attendance as part of the grade if you're on a shift like that. Also can't get another job that might turn into a better opportunity, they won't deal with your constantly changing availability.
companies don't even have to worry about that shit anymore. things are so perilous that there will always be people desperate enough for anything no matter how shitty the conditions
