The end of tenure

The end of tenure

From The Chronicle:

Over just three decades, the proportion of college instructors who are tenured or on the tenure track plummeted: from 57 percent in 1975 to 31 percent in 2007. The new report is expected to show that that proportion fell even further in 2009, dropping below one-third. If you add graduate teaching assistants to the mix, those with some kind of tenure status represent a mere quarter of all instructors.
