Job instability
(or, why your favorite lecturer may not be around next year)
Only a fraction of UC lecturers have some modicum of job security - the majority are forced to reapply to their jobs every year, and lack even the right to a transparent evaluation process.
As a result, between 25 and 30% of lecturers are driven out of their jobs each year - whether because they were not rehired, or because they had switched to a better compensated and more stable job.

Fact-checker
The university would have you believe that lecturers are simply not interested in long term employment - they are perhaps in transition from graduate school to a tenure track position, or simply teaching a class as a diversion, at the conclusion of some other professional career. Yet the UC's own published statistics show that, as a group, lecturers are in the prime of their careers. Most are neither fresh out of graduate school, nor nearing retirement and in need of a hobby job. Which is good, considering that they often teach large core classes, which require experienced instructors.
