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, you are hired to do a thing that requires skill. Everything requires skill, if something did not require some level of skill there would be no job.
Again, depends on your definition of skill.
I would not classify the ability to grab, lift or carry as a “skill” in terms of labour. You are hired to do work. But if basically any able-bodied person could do the work, it doesn’t require skill.
