In their controversial 2016 paper in this journal, Brennan and Magness argue that fair pay for part-time, adjunct faculty would be unaffordable for most colleges and universities and would harm students as well as many adjunct faculty members. In this critique, I show that their cost estimates fail to take account of the potential benefits of fair pay for adjunct faculty and are based on implausible assumptions. I propose that pay per course for new adjunct faculty members should be tied (...) to pay per course for new full-time non-tenure track instructors or to pay per course for new assistant professors. That framework for adjunct faculty justice yields an aggregate cost range of $18.5–$27.9 billion, one-third to one-half lower than the range computed by Brennan and Magness. Its opportunity cost would not be borne by students since students and faculty are complements, not substitutes, in the educational process. Instead it could be financed by reducing spending on non-educational purposes. Current adjunct faculty members would be protected from job displacement in this justice framework. The real obstacle to achieving justice for adjunct faculty is the priorities of university administrators, not budget constraints or opportunity costs. (shrink)
