Here is a wonderful piece from an adjunct blog I recently found. I am pasting in the beginning of the manifesto, but invite you to go read the rest, and explore the archives!
The crisis of identity for adjunct faculty takes different forms, at different times, in different places, but is an undercurrent that flows through their lives. Adjunct faculty, a de facto underclass, carry the institution of higher education on their backs for just above poverty wages. Some [of us] are simply so busy maintaining a professional practice, and trying to make ends meet, under oppressive conditions, [we] hardly have time, between campuses, to consider [our] dismal fate. Rationalization is the dominant coping mechanism.
