You’re trying to make a weird semantic distinction that doesn’t really accomplish anything. Unskilled labor doesn’t mean undignified or unworthy of respect, it is just a description of a certain kind of work with essentially no barrier to entry. Again it’s very uncommon in modern advanced economies but in the past (and today in some very poor areas) you’d have people whose job it was to push millstones around in a circle all day, a job that is also done by literal donkeys. That is not skilled labor.
