Most “unskilled labor” is heavily skill dependant. You wouldn’t want a chef, builder or plumber who didn’t know what they were doing. And for production: machinists, mechanics and foremen make or break profit with their skills.
So what’s a better name for these jobs?
I was a waiter in and out for a year. It’s tiring and you can end up exhausted.
But the needed skills were very simple.
Maybe it depends on the type of waiter? I served on the bar and only drinks, which was fairly easy. And of course I didn’t own the place or anything. We also didn’t serve any special cocktails or weird drinks. I didn’t think that a special skill was needed to do what I did.
