> Those employers don't care.

I think parent's point is that employees care. Employers probably don't care that they're paying employees minimum wage, but if other places pay higher than that the the employees (who do care) would switch to the other jobs.

>I suspect it's deliberate. If you can't plan your life, you are a slave to work.

Are you suggesting they're deliberately doing this so "you are a slave to work"? How does the employer benefit from this?

The workers can't do things like go to school or do anything productive, so they're stuck at that job for a much longer time than if they could better their circumstance.

It also gives the employers the ability to point towards any deviations from being available on short notice as a reason to legally fire people. You either give up your life to your low level job or you provide ammo for them to remove all of your legal protections because you aren't being fired for a legally protected reason, but because you violated policy or weren't flexible enough
