Most “unskilled labor” is heavily skill dependant. You wouldn’t want a chef, builder or painter 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?
Edit: I have been told that plumbers don’t qualify as unskilled, and as such they have been exchanged for painter.
We have called people without a specific trade a Labourer, it’s bot that they are unskilled, it’s that they aren’t specialized.
Just call it “generalist labo(u)r” or “general laborer”.
That’s what the company called them.
