I’m not a native English speaker and I have a hard time figuring out what is behind the term "mechanics" here. What I find online seems to point to working in a garage and knowing how to do repairs, not being a line worker or technician in a factory doing maintenance on machinery like you say. In the article it’s confusing, they talk about servicing and trades school, so not really factory work. Maybe I’m lost in translation but it looks like even English speakers are not using a vague term to talk about different things here? What does is 120k job really about, working in a Ford garage fixing cars or being a factory technician?
