Sometimes power and authority is used synonymously because of their objective of influencing the behavior of others. However, there is difference between the two. Power does not have any legal sanctity while authority has such sanctity. Authority is institutional and is legitimate. Power, on the other hand, is personal and does not have any legitimacy. But stilt, power is a crucial factor in influencing the behavior in organizational situation.
Sources of Power
John R. P. French and Bertram Raven identified five bases or sources of power: legitimate, reward, coercive, expert and referent power.
Legitimate Power
A person’s position within organization provides him with legitimate power. The organization gives managers the power to direct the activities of their subordinates. Legitimate power is similar to formal authority and hence it can be created, granted, changed or withdrawn by the formal organization. The structure of the organization also identifies the strength of the legitimate authority by position location. For instance, higher-level positions exercise more power than lower-level positions in a classical hierarchical organizational structure. Organizations vary in how much legitimate power they grant to individuals. In such organizations, everyone knows who has the most power and few people challenge the power structure.
Reward Power
This type of power is the extent to which one person has control over rewards that are valued by another. The greater the perceived values of such rewards, the greater the power. Organizational rewards include pay, promotions and valued office assignments. A manager who has complete control over such rewards has a good deal of power. Manager who uses praise and recognition has also a good deal of power.
Coercive Power
People have, coercive power if they have control over some form of punishment such as threat of dismissal, suspension, demotion or other method of embarrassment for the people. Perhaps, a manager can cause psychological harm also lo an employee. A manager’s coercive power increases with the number and severity of the sanctions over which the manager has control. Although the use of coercive power is often successful in the short run, it tends to create resentment and hostility and therefore is usually detrimental to the organization in the long run.
Expert Power
It is more of personal power than organizational power. Expert power is that influence which one wields as a result of one’s experience, special skill or knowledge. This power occurs when the expert threatens to withhold his knowledge or skill. Since any person who is not easily replaceable has more power as compared to those who are easily replaceable. If the sub-ordinates view their superior as competent, and knowledgeable, naturally they will obey and respect the superior. To the extent, that a low-ranking worker has important knowledge not available to a superior, he is likely to have more power.
Referent Power
A person who is respected by certain others for whatever reason has referent power over those people. A person with referent power may have charisma and people who respect that person are likely to get emotionally involved with the respected person and identify with, accept and be willing to follow him or her. People with referent power are often imitated by others with the star’s actions, attitudes and dress. This imitation reflects the rising star’s power over the imitations.
