Dynamics of social interaction are present in all organizations. In any given organization there're individuals who do the bare minimum to get by. There're those who would rather complain that do any productive work whatsoever.
Every organization also has overachievers as well as those who are completely devoted to the organization. These people stand in contrast to those who are just using the company as a stepping stone to a better opportunity in the future. Every organization has people are fine with the way things are as well as those who want to change everything.
The best leaders seek the find the balance between cajoling, pushing, forcing and suggesting. He/she needs to know how to speak quietly with individuals as well as forcefully with a whole group. He/she needs to be a good listener and not just a commander.
