Fry Cooks have to take classes on food safety. They are skilled labor. I'm not sure about the Amazon box guy but maybe both should have the trade union you need to be "skilled labor" in the actual sense of it.

Instead of reasonable pay, you’re offered a title and persistent lies about career growth. And it feels pretty shitty when you’re confronted with the fact that you’ve invested a bunch of energy in something that won’t pay off.
