freeway flyer
n.— «Especially since the effects of Proposition 13 began to kick in with a vengeance, community colleges have become ever more dependent on cheap labor provided by part-time faculty, who are often known as “freeway flyers” because they must drive from campus to campus to make a living. Rules permit part-timers to carry only half a full schedule at any one campus; they make up the difference flying the freeway to distant colleges.» —“Students and teachers suffer when money is scarce” by Eric Caine Modesto Bee (California) June 18, 2009.
