TBH carolina, I don't particularly care what they do when they leave, isn't that awful? It is just that if you have sat in front of a class of disruptive , abusive 14-16 year olds who do no work, and only want to be a pITA, it gets to you after a while. And schools are not baby sitting services. If they will not work with us, and in doing so prevent others working, they should go somewhere else.
Now, like Edam a feel that one of the best ways of coping with these kids is to give them appropriate courses in things that they are prepared to work at. Mind you, some of them just plain old don't want to work. My BIL runs his own electrical company and has lost count of the aprentices who fail to turn up to their collage classes, skive off work etc.
