OP did not say anything about skilled workers who make things with their hands. You are describing an artisan or craftsman, or at the very least a tradesman.
The quote is talking about manufacturing labor. This is the guy on the assembly line who lowers the press, makes his thousandth widget for a day, and then lifts it up. Rinse and repeat.
