Firing a teacher in California is difficult and time-consuming

From The Los Angeles Times: It's remarkably difficult to fire a tenured public school teacher in California, a Los Angeles Times investigation has found. The path can be laborious and labyrinthine, in some cases involving years of investigation, union grievances, administrative appeals, court challenges and re-hearings. Not only is the process arduous, but some districts are particularly unsuccessful in navigating its complexities. The Los Angeles Unified School District sees the majority of its appealed dismissals overturned, and its administrators are far less likely even to try firing a tenured teacher than those in other districts.
