There is no perfect leader; only the right leader for a given situation
Every company I know has included leadership in their performance development process, still every time I ask the people what leadership means to them and what leadership styles they encourage, they start with a big pause and continue with a cliché about inspiration and collaboration.
If you are searching for leadership styles theories you will find styles like Autocratic, Laissez-Faire, Democratic or Commanding, Visionary, Affiliative, Pacesetting, Coaching, etc.
What is your preferred leadership style? Do you have a style?
