Things have of course significantly moved on from that master-servant model. The computers have taken over the mundane routine work. Internet is here. In this modern climate, the coercive leadership model in my view no longer works. Why? I think that one of the major reasons is that workers are now better educated and better informed than they were then.
They are also more independent. They know that they can take alternative options. The global job market has opened up. The modern leadership style needs to attend to these factors. Leaders not only need to be knowledgeable, they now need to lead a very knowledgeable team. Talking about leadership also brings up debates on issues such as: Are leaders made, or are they born?
