This is the second book in the Leadership 3.0 saga and it is the quintessential tool for someone with the talent to lead work teams under Christian principles. In simple words, this book has to do with the modus operandi of a person who, once exercising the functions of group leader, needs to know how to behave before it. For its study it is divided into four main parts: 1) How to become a team leader? 2) The responsibilities of the team leader, 3) The team leader as an intermediate point between his authorities and the team and 4) The legacy of the team leader.
