This is going to continue until #1. Teachers refuse to join unions or school districts that perpetuate this vicious behavior, #2. Until private and charter schools who do see the damage begin to attract a lion’s share of good teacher’s.
#3. Until parents and students themselves bring this subject to the public forum. That will include parents of the good students suing or exposing the harassers. Their child is being cheated of a public education due to lazy, low wattage truants. If we even have Truant Officers anymore, maybe they will need to be named, shamed and dragged into the courtroom before a certain class of people begin taking school more seriously again. The 47% of the population aka; the blissfully ignorant dummies will need to be told by someone like Oprah, or a currently popular bimbo like Beyonce or their peers that lying about your teacher is no longer cool. In fact, you and your pals may get sued for slander, and put into an alternative school.
It's not only the "low-wattage" kids doing this either. It's any kid who is lazy, spoiled, and doesn't want to work at the level the teacher demands in the classroom, and/or who doesn't want to wean themselves from poor and unproductive classroom behavior, such as using cell phones during a lesson. They resent any use of the word "No" or the phrase "You can't do that." It's also kids who just personally don't like the teacher. So, in addition to hours of writing lessons and grading papers, now the teacher has to be Mr. or Ms. Popularity and emulate Cedric the Entertainer to boot. Believe me when I say that plenty of the aforementioned students are NOT from "a certain class", shamefully. They use their brains to foment vicious mischief when they could be using them to get top grades. I have heard recently that education program enrollment in colleges is down 50%. Why am I not surprised?
