Not long ago I read an article about self-defense classes for teachers in Colorado. You can find the article by Googling: Self-Defense class for teachers, Boulder Daily Camera I also noticed a new book on Amazon called "Self-Defense for Teachers: An Unfortunate Necessity for Modern Educators". Do you think this type of stuff is necessary. I was just wondering if any of you have ever feel unsafe while teaching. Do you have this type of safety training in your schools?
