From The Atlantic:
Imagine meeting your English professor by the trunk of her car for office hours, where she doles out information like a taco vendor in a food truck. Or getting an e-mail error message when you write your former biology professor asking for a recommendation because she is no longer employed at the same college. Or attending an afternoon lecture in which your anthropology professor seems a little distracted because he doesn’t have enough money for bus fare. This is an increasingly widespread reality of college education.
Many students—and parents who foot the bills—may assume that all college professors are adequately compensated professionals with a distinct arrangement in which they have a job for life. In actuality those are just tenured professors, who represent less than a quarter of all college faculty. Odds are that students will be taught by professors with less job security and lower pay than those tenured employees, which research shows results in diminished services for students.
Nearly a quarter of all adjunct professors receive public assistance, such as Medicaid or food stamps.
Adjunct professors earn a median of $2,700 for a semester-long class, according to a survey of thousands of part-time faculty members. In 2013, NPR reported that the average annual pay for adjuncts is between $20,000 and $25,000, while a March 2015 survey conducted by Pacific Standard among nearly 500 adjuncts found that a majority earn less than $20,000 per year from teaching. Some live on less than that and supplement their income with public assistance: A recent report from UC Berkeley found that nearly a quarter of all adjunct professors receive public assistance, such as Medicaid or food stamps. Indeed, many adjuncts earn less than the federal minimum wage. Unless they work 30 hours or more at one college, they’re not eligible for health insurance from that employer, and like other part-time employees, they do not qualify for other benefits.
