One of Inside Higher Ed's columns features a true doozy of a question: "My chair just asked me to teach a course I've never taught, and which I think is beneath me..." We have "faculty with entitlement issues" for $300, Alex. I teach freshman composition, I teach British Literature II, I teach intro to literary analysis. Occasionally, I teach one of our department's first-year world lit courses. The bulk of my teaching load comes from introductory "service" courses, not from advanced courses in my field or graduate seminars. This arrangement is par for the course (so to speak) for anyone not at a Research I, and can take far more drastic forms at schools with 4-4 and 5-5 teaching loads (multiple sections of comp, courses far outside one's specialization, etc.). Those annoying service courses--especially the ones with gen ed credits attached--pay your department's bills and/or are the building blocks of your major. They aren't "beneath" you; without those courses, your position very likely wouldn't exist.
