Quite a bit O/T, but relates to teachers (who are often put in the category of “greedy union thugs” as well). Just ran across the video that was shot by a student in what appears to be a high school math class. The student posted it on YouTube, apparently because the student thought it was funny that the teacher “lost it.”
Personally, it broke my heart. It’s not the teacher’s behavior that’s so bad. Look at what the students are doing, and listen to what they are saying.
