The majority of teaching is done by "adjuncts" who are not professors, are ineligible for tenure, and don't do research. They have to re-apply for their job every semester. People rarely do it long-term, though it sometimes employs academic spouses and people who are using it for health benefits while pursuing a side business. It's certainly not a career. My mom was a public high school teacher. When I described the conditions of working as an adjunct, her knee jerk reaction was: "That's why teachers have a union."
