There's clearly a willing contingent that would instantly take them up on it.
Instead they choose to sever people who might really need the job, throwing them into the crocodile pit of the current job market.
Or they push to make working conditions annoying enough that people who have options voluntarily leave (this part of it makes zero sense to me, these are typically the people you can least afford to lose).
Meanwhile the people who stay are made increasingly miserable, both as a result of the voluntary attrition measures, as well as having to operate for years in an environment with zero job security and no end to the layoffs in sight.
How is any of this better than just yanking the bandaid off, and letting workers have a hand in their own fate?
It feels very "the cruelty is the point" to me
