In school it was dreadful to be bullied, and then have a teacher say "well shake hands and forget about it", how on earth was that going to help and stop them doing it?
Thats when you learn to avoid, rather than ask for help, as the so called intervention or help is useless anyway. This was when I was young and I would like to think that it has improved in some schools at least.
Unfortunately, I don't think it has improved much at all. I think teachers are, on the whole, more aware of bullying being a problem, but I don't think that has led to much specific action on their part.
Many schools have the 'mediation" meetings -- and I agree, those are worthless and come down to exactly the sort of "shake hands = the bully wins" crap that you decry. It's just another way to "pretend" it's being dealt with when in fact, nothing is really happening.
I also think -- on a high school level anyway -- many teachers are also afraid of confronting bullies, and don't want to face their responsibility -- so they pretend they don't see the bullying, or they pass it on to the administrators where nothing ever happens.
In my classroom, I gave up on the school 'process' for [non]dealing with bullies. If a kid bullied someone in my class, I bullied the bully. Crude, maybe, but I found that after a couple of incidents the bullies got the message and they didn't mess with my kids.
There are a few teachers who get the reputation of having "safe rooms" and kids know they can be there with less threat of being targetted by bullies.
