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’ve done one or two night of hospitality work. It wasn’t fun, and I had fairly easy roles. I appreciate it when others do it for me.
