No need for mind games. Leadership is not rocket science.
The daily tasks of managers revolve mostly around numbers, statistics, competition, and ultimately, success. What we often forget is that a big aspect of leadership relies on managing relationships. Many see this as an unnecessary burden, at best. So, what could be better than being able to reach into a box of psychological tricks and swiftly finish off disagreements or completely avoid conflict? I am afraid that is too easy. If you want to be successful and retain competent employees for the long term, you would be well advised to stay away from such gimmicks. Those who lead people have a responsibility - they are responsible for treating their employees with decency. That leaves no room for cheap tricks or power games.
