No, no, you see, it's actually so empowering for the worker because they can quit at any time with no notice! Isn't that so empowering! In fact, I almost think that the balance of power goes too far in the workers favor on this and we need to give some of it back to the poor employers who are just always walking on eggshells since they can be quit on at any time!
/s just in case
It's so insane that anyone can argue that at-will employment is anything other than a shitty employer's wet dream.
