As I mentioned at the very beginning of my presentation, the real key is to aim for prevention, and the base for that really is awareness.
Even though, as Pierre says, these sessions are only three hours, it's three hours that you didn't have before that are now devoted to this topic. One would hope that training will give rise to a greater sense of awareness. Certainly the kind of media coverage that instances like this provoke also helps you realize how to build a better working environment in your office.
