Everyone talks about teamwork, but not everyone gets the best from their teams. Teamwork just does not come naturally. This chapter explains why and what we can do about it. Principles and practical procedures are offered for initiating and sustaining productive teamwork. The functions of seven different safety teams are described. Each of these teams contributes to improving the human dynamics of occupational safety, as taught in this book. Each team depends on the output of other teams to optimize the system and cultivate a Total Safety Culture.
