There is one very important aspect which enables any company to succeed or fail. This aspect is related to the leader who is driving the organization towards attaining its objectives. It is really very important to understand that which kind of leadership style is the leader adopting to manage its organization as well as the human resources. There are many different types of leadership style that can be adopted by the leader of any organization and this leadership styles defines the way the employees are treated in any organization. Different types of organizations may adopt different theories of leadership. There are two types of theory: situational theory and the behavioural theory. Let us discuss both of them individually. Behavioural theory deals with the behaviour of the leaders. They are mainly on the behaviour of different leaders of different organizations. Leaders are prone to enjoy power and they are less tended towards affiliation. The key to success for the leaders is to control their power and take decisions intelligently. Other leadership style names here are the situational leadership. This is as its name suggests and deals with the leadership according to the situation. Now this category of leadership style consists of 3 different types of leadership styles. These comprise the democratic leadership style, authoritarian leadership style, and laissez faire leadership style (Porter, 2012). Let us discuss these three also in detail. The first is the authoritarian style of leadership. This style of leadership consists of the situation where the leader is very determined that how the work needs to be done and he believes in ordering the employees of how the work needs to be done. The leader is very adamant here in how the work needs to be completed and do not entertain to give the authority to anyone else.
