Skilled labor meaning it took more than a twenty minute introduction for the job. If the guy flipping burgers can cook multiple burgers at multiple Temps, than that would classify as skilled labor. They guy that drops the fries in the fryer and just has to wait for the ding, not skilled labor. Another example, a welder who knows how the mixture of gas affects the welds, skilled labor. It’s knowledge of why and how to get to the end result rather than following basic instructions just because that’s what you were told.
