While increasing attention began to be focused a decade ago on the scandalous misuse of part-time or “adjunct” faculty in colleges, their use has persistently spread. In fact, new varieties of “temporary” positions continue to be invented by college managers. “Part-time” faculty now include some who teach what amounts to a full load, but who are paid on a credit hour or per course basis, others who scramble for one or two courses each term and are paid flat rates, as well as a few whose salaries and benefits are prorated fractions of those of a full-timer. But there are now many “off-tenure” full-time appointments as well: “lecturers,” whose contracts are renewed every year or two but who may remain in their positions, without tenure, indefinitely; “nontenure-track” instructors and assistant professors, who may stay at an institution for four, six or more years but who, at the point of a tenure decision, must move on; “replacement” appointments, who fill lines for a year or two and then migrate to similar positions elsewhere. I shall use the term “adjunct faculty” or “adjuncts” to describe this quite varied group of individuals, for while the word is not precisely appropriate in all cases, its dictionary definition calls attention to the fact that such faculty, while “joined or added” to the institution, are in critical ways “not essentially a part of it.” Handwringing over the plight of adjuncts has brought no relief, and even most union contracts have so far been marginally helpful. That should be no surprise, for the exploitation of adjuncts serves a number of crucial interests of college managers and of those to whom they report. It is important to identify these interests more clearly if the abuse of this large number of our colleagues is ever to be brought under control, much less halted. For the exploitation of adjuncts is not a function of managerial nastiness, nor is it—any more than was the War on Vietnam—an unfortunate product of historical “accidents.” Rather, it is rooted in a particular conception of college management designed to serve historically distinctive social and political interests.
