This book analysis how being brought up in some culture makes us predisposed to accept some "rules" as the norm, which makes us somewhat intransigent when someone doesn't follow the same rules we do. In a work environment, this may become a problem. I would not say the book is eye-opening because I believe most people have been in these situations and noticed the differences, but the skills to handle them are well explained and clear. I feel I am more prepared to handle a group of people from difficult cultures after having read this book. I will keep using it in the future.
