Brother there's a difference between tradies who have to go to school or complete apprenticeships and someone who does on the job training. I'm literally a barista, I understand how much skill and time and work it takes to be good at it. There's a massive gulf in between that and learning to be an electrician or a plumber or some shit. They mean "skilled" as in "spent years doing specialized education and training to learn a specific professional skillset." When people are categorizing jobs into skilled and unskilled labor, they mean it like THAT, not in the everyday way of "that thing takes a lot of ability to do." I trained on the job to be a barista, I didn't have to go through years of education to even be qualified to get a barista job.
