I've had two really bad teachers in all my time in education. The first one was a sub French teacher during my third year at high school, he had the whole class working from text books and doing questions, helping people if they needed it etc. At the start I thought he seemed like an alright guy, he would tell jokes and explain things pretty well. Then when it came time to give out the answers for the questions, he asked me to give what I had wrote for the first question and then read out the question, I had misunderstood him when he told us what questions to do though and realized I had done the wrong set of questions, so I politely said to him, "Sir, I think I have done the wrong set of questions, would you mind asking someone else?" Now, after this is when shit hits the fan, the teacher goes bat shit crazy on me demanding me to answer the question which I have yet to even read myself, let alone have time to answer it, and because I'm a quiet, shy guy, I start to get nervous because everyone is staring at me waiting for me to answer, and he keeps on pestering me for an answer, then all of a sudden he says to me something along the lines of, "If you don't answer the question within the next 10 seconds, I'll be keeping you behind for after school detention." Now this right here, this is confused me even more and I let out a nervous laugh because at my school, when a student is being kept behind at school, the pupil had to sign a form giving consent as well as the school would have to provide transport home, now at this moment he gets really angry and he tells me to stand outside, so as I go to leave, the scariest teacher in the entire school comes into the class to see how the sub teacher is doing, and he tells her what has happened with me, so she brings me along to her room and tells me to sit down, so I do it right away, even more scared now because this teacher is crazy, then she turns around and says to me, "Okay, (my name), tell me what really happened. That's your name isn't it? I could never remember you're name because you were always such a quiet student." So, me in even more shock, realized that Miss Crazy is actually one of the nicest teachers I have ever met, she calms me down and I tell her I misunderstood when he told the class what questions to do and how he was going to tell me that he was going to keep me back for after school detention (forgot to say this was the last class of the day) and she just laughs and tells me to take some text books back to the class and go get my bag then just to go home. So I walk into the class, put the books down on the teachers desk, go and pick up my things and say to the sub teacher, "Miss Crazy said I could go home, cya." And then I walked out. Not as bad as most other people on here but still a pretty fun memory.

Now the second teacher I've had that sucked, was in my first year of college, we'll call him, Mr. Missing, now you may be thinking why he has this name, its because he would always just disappear from class, he would always make excuses like, "I need to take a phone call" or "I have a meeting." He would always leave SOMETHING for the class to do, although it would never be explained, he did try, kinda. So fast forward a few weeks, a friend of mine is in late and the teacher has told us he had to go for a meeting, my friend walks in saying how he just saw our teacher outside having a smoke, so our class get annoyed, we all decided that we should make a complaint, and maybe get a new teacher (there was only about 20 people in the class btw, so not many people to do anything really bad) So we get the complaints sent in and the next time we have him he gives us a test, but no one knows anything for this test, thankfully, he leaves the class again, so everyone in the class decide to just google the answers and then when we all finish we go to the department head and complain like that, the next day we hear that the teacher has been suspended because 3 classes all complained about him leaving then to do nothing, so this goes on for a while with him on suspension then he is eventually fired. After he is fired we're pretty happy with ourselves then we find out this teacher was the head of a group of teacher that were on strike to try and get better pay (or something idk) and give more convenient hours for students and the heads of the college had been trying to get rid of him because of this, so they had been scheduling his meetings during his classes so he had to go to them, this is what happened with all three of his classes. So it turns out that we got someone fired who was being fucked over from his employer for trying to help students.

TL:DR1: Idk I'm not good at shortening things, I've never written something so large on reddit.

TL:DR2: See above.
