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 think most of those jobs are actually considered skilled jobs. Are they not?
When I think unskilled job I think picking fruit on the fields, cashier, delivering packages (though you need the driving skill so I don’t know) job that does actually not take much skill, and could probably be 100% learned how to do right in a week.
Nothing bad with an unskilled job anyway. If it needs to be done it needs to be done. Not because doing it takes no special skill means that it is less important.
