6. Bad Teacher - Elizabeth Halsey
The title pretty much gives this one away, but how or why this woman ever became a teacher in the first place is a complete mystery. Halsey is a borderline alcoholic and drug abuser who regularly assaults her students with vocal tirades. She also has no moral hangups with manipulating her students or their parents for financial gain, like when she recruits her seventh grade girls for a sexually provocative car wash to raise funds for breast enlargement surgery. Even if Halsey wasn't slumped over in her chair due to a nasty hangover on a day-to-day basis, she is simply too selfish to make the sacrifices that are necessary to be an effective teacher. Although Halsey's behaviour is shocking to say the least, some of the blame has to fall on the school that hired her. Apparently they've never heard of performance evaluations.
