@BossMadam Teachers do get abused, often several times daily, for up to an hour each time. I started teaching 20 years ago. At the time, I'd have one or two classes I wouldn't look forward to, knowing they were extremely tough due to a few of "those" students (the ones intentionally ruining my lesson).
Nowadays, I may have one or two classes if I'm lucky where this disruption doesn't occur on a regular basis. Almost every class has two or more students in them who are hell-bent on destroying learning. They do that by throwing objects, punching things, swearing at each other and me, severe gaslighting backed up by their mates (you can watch them say/ do something and they swear they didn't and get backed up by others in the classroom), twisting your words, threatening you.
The last one has a huge impact now, because they often don't physically threaten you. No, instead there are a number of students now using "safeguarding" to threaten your livelihood.
I've had a colleague in my last job repeatedly being accused of getting into a student's face and shouting at them when in reality he'd raised his voice to prevent that student from getting injured. He got dragged into safeguarding by one particular student so often that he now has a mark on his file - never anything proven, but a "concern".
I have had another colleague in a previous school falsely accused of sexual misconduct because the student had taken a dislike to him. Suspended, had to leave because the rumour went around students and he was systematically bullied.
Every joke you make, every slight negative remark, every action can be twisted and it only takes one student to make an accusation for your job to fall apart. This is where real stress comes from for a lot of teachers now; you have to watch every word you say and everything you do so carefully. You're on constant high alert.
Add to that the lack of breaks (try being on a heavy period day and not being able to go to the loo because you teach and then have break duty, so you have to last 5+ hours without toilet access and stress about leaking), the regular 12-hour days, high-stakes observations where you have to perform no matter what the situation and often very short deadlines for just abut anything and teachers are on perma-stress for up to 8 weeks at a time each half-term.
Yes, that easily leads to PTSD.
