Who are "contingent faculty"? Depending on the institution, they can be known as adjuncts, postdocs, TAs, non-tenure-track faculty, clinical faculty, part-timers, lecturers, instructors, or nonsenate faculty. What they all have in common: they serve in insecure, unsupported positions with little job security and few protections for academic freedom. And they are the vast majority of US faculty today. Something needs to change.
