Keith Hoeller is an adjunct professor. He teaches philosophy for a living at Green River Community College, just outside Seattle. He has also spent much of the last two decades ruminating about the bigger picture for those at his level of the professorial pecking order. Over the years, Hoeller has lobbied relentlessly for adjunct-friendly legislation in his home state--with a focus on "equal pay for equal work"--and helped initiate lawsuits that ultimately made health and retirement benefits accessible to more adjuncts there. That combination of deep thinking and forthright advocacy has given Hoeller a reputation as a gadfly, as have the nearly two dozen op-ed essays he has written for publications like "The Seattle Times" and "The Chronicle Review." His columns give an insider's view of life as an adjunct, as well as sharply provocative opinions on part-time lecturers' relationship with unions.
