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?
The waiters here carry a little tablet that contains the menu, can store orders and even does the maths in case you want to split-pay at the end.
That leaves being “somewhat sociable” as the remaining skill. True … I definitly couldn’t do that. I’d probably throw a drink at an annoying customer after a few days.
