Higher education is probably the only industry in which a person is expected to get another degree and take a pay cut.
That's what happened to me, and others in my graduate school, when we finished our degrees. We found that we were making less as adjuncts than we did as TAs or fellows.
Another odd thing about higher education, and education generally: We the only professionals who are subservient to the office staff. In any other profession I know of, the office staff serve the professional.
What are some of the other oddities about being in higher education that most people don't know about unless they're in it?
