Power Vs Authority

Effective leaders develop and use power, or the ability to influence others. The traditional manager's power comes from his or her position within the organization. Legitimate, reward, and coercive are all forms of power used by managers to change employee behavior and are defined as follows:
• Legitimate power stems from a formal management position in an organization and the authority granted to it. Subordinates accept this as a legitimate source of power and comply with it.
• Reward power stems from the authority to reward others. Managers can give formal rewards, such as pay increases or promotions, and may also use praise, attention, and recognition to influence behavior.
• Coercive power is the opposite of reward power and stems from the authority to punish or to recommend punishment. Managers have coercive power when they have the right to fire or demote employees, criticize them, withhold pay increases, give reprimands, make negative entries in employee files, and so on.
Keep in mind that different types of position power receive different responses in followers. Legitimate power and reward power are most likely to generate compliance, where workers obey orders even though they may personally disagree with them. Coercive power most often generates resistance, which may lead workers to deliberately avoid carrying out instructions or to disobey orders.
Unlike external sources of position power, personal power most often comes from internal sources, such as a person's special knowledge or personality characteristics. Personal power is the tool of a leader. Subordinates follow a leader because of respect, admiration, or caring they feel for this individual and his or her ideas. The following two types of personal power exist:
• Expert power results from a leader's special knowledge or skills regarding the tasks performed by followers. When a leader is a true expert, subordinates tend to go along quickly with his or her recommendations.
• Referent power results from leadership characteristics that command identification, respect, and admiration from subordinates who then desire to emulate the leader. When workers admire a supervisor because of the way he or she deals with them, the influence is based on referent power. Referent power depends on a leader's personal characteristics rather than on his or her formal title or position, and is most visible in the area of charismatic leadership.
The most common follower response to expert power and referent power is commitment. Commitment means that workers share the leader's point of view and enthusiastically carry out instructions. Needless to say, commitment is preferred to compliance or resistance. Commitment helps followers overcome fear of change, and it is especially important in those instances.
Keep in mind that the different types of power described in this section are interrelated. Most leaders use a combination of these types of power, depending on the leadership style used. Authoritarian leaders, for example, use a mixture of legitimate, coercive, and reward powers to dictate the policies, plans, and activities of a group. In comparison, a participative leader uses mainly referent power, involving all members of the group in the decision-making process
