My initial reaction is, "Not for a second."
However, I remember being in school where I needed to take certain classes to graduate and only one bullying teacher taught those certain classes (primarily gym/phys. ed. classes, where the uniforms showed off that I was the tiniest, skinniest kid by far in each grade, and that just fueled the chastising/bullying of the teacher and students). One gym teacher pushed me, unexpectedly, into the deep end of the pool, knowing I was too skinny to float and not a strong swimmer: that time the whole class stood up for me and someone ELSE accused her of pushing me in first, not I! Several students jumped in and helped me out of the pool, sputtering and coughing from inhaling a breath of water unexpectedly.
A number of childhood diseases, added to my 1% size for my age, was criticized by the Health teacher frequently, once in front of the whole class because I answered a question about NOT eating fresh fruits and vegetables and from all four food groups as a good answer (because I was dangerously allergic to 3 of the 4 food groups and all fresh fruits and vegetables).
Though my parents contacted the schools over the years, verbally and in writing, nothing was done: the gym and health teachers were teaching lessons "to the whole class" on how to be healthy and fit and therefore had done nothing wrong (except to my already shattered self-image). No other teachers or schools or home-schooling were options for me, either, so there I was stuck.
On the plus side: I still look 10 years younger than my actual age and I'm in my 40s. And, it has been about 3-4 years since I was carded for an R-rated movie.
If I had had a child, and found out a teacher was bullying her/him, I would have done everything in my power to see that this teacher was punished and put in a position where he/she could never bully another child. I'm learning to stand up for myself and those I love the older I get. "The system" isn't always broken, and I'm not afraid to call the police, lawyers, the District Attorney's office, and even federal-level contacts, as appropriate, to make things happen if earlier attempts fail.
