LMAO, that's a MADE UP job. It literally doesn't exist. The amount of mandatory safety training from working in any factory environment excessedes that. That's before you can start learning how to use the production software and automation that the company uses to measure productivity. Finally you have to do the actual task and learn the processes and exceptions that have made it so that the job isn't cost effective to automate in the first place.
Now that's a big company environment. Big companies are the only ones with the economies of scale required so that your can even have employees that only do one thing. At a small company everyone has to wear many hats and there is no such thing as an person that does only one job "you could learn in 10min"
It's easy to imagine "unskilled labour" when you make it up in your head. What sucks is when you then use it to dehumanize and underpay real humans because of your made up fantasy of unskilled labour.
