Non-tenure track instructors teach nearly 49 percent of undergraduate courses in the United States, the Chronicle of Higher Education reports.
Many of those instructors work part-time and aren’t paid as much as their tenured or tenure-track counterparts. Non-tenure track instructors make up nearly 70 percent of the professoriate in the U.S.
This information comes from a report issued by the American Federation of Teachers, which worries that academic freedom is compromised because most of the undergraduate instructors in the country lack the job security that comes with tenure.
When you can lose your job at any time because of budgetary reasons or because of something you said or did, I’d say academic freedom is compromised.
