Drivealot is a car company in South Africa that employs many people on different levels in the organisation. Mr Johnns, the managing director of Drivealot, only communicates with employees when he is giving instructions. In this, the organisational communication in Drivealot is very formal, downward, one-way and task-oriented. Mr Johnns sends messages to the two managers directly under him and then instructs them to talk to the employees under them. He does not talk to employees at the bottom of the organisational structure directly. What network roles can be identified from the scenario above? Opinion leaders and bridges Cosmopolites or boundary spanners Isolates and liaisons Members and gatekeepers
