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?
Yes but compare that to a ‘skilled’ profession. 4 year degree, 5 years training under a licensed professional, series of examinations, and continuing education requirements.
It’s not that one is ‘unskilled’ in a vacuum, it’s that it has relatively less time/effort investment to reach ‘acceptable’ performance
