Most colleges and universities hire adjunct on an as-needed basis. As full time faculty and enrollment needs change adjunct may not be asked back. It is rarely a reflection of the quality of the adjunct. I am sorry Ms Weis lost her position but that is the nature of adjunct work. Adjuncts, who are usually underpaid and overworked, are known as the academic slave class. I shall pray that she can find an adjunct or a full time position if that is her desire.
