As Toffler states (1990, p.1) “Power is inherent in all social systems and in all human relationships”. Power exists everywhere and plays a significant role in society. In a country, the government has the power to make and implement policies; in a workplace, the manager has the power to assign work to employees. Because of its pervasiveness, it is difficult to give a clear explanation of what power is. However, power is often defined as the ability to influence the behavior of other people (Weber, 1978, cited in Lammers, Stoker, & Stapel, 2009; Wrong, 2005, cited in Domhoff, 2005). The use of power can lead to both negative and positive effects on others. So, from a negative perspective, power could be considered bad, because the unprincipled use of power can cause violence, corruption, and privilege. However, it is also necessary to have power, because judicious use of power could effectively avoid these negative influences and help improve the productivity of an organization and maintain the stability of a country. Therefore, power is a necessary evil that enables achievement. If power can be used appropriately, the benefits of using power will outweigh its negative influences. In politics, legitimate power and coercive power could be used as tools to protect citizens' rights and maintain the stability of a country. Straker (2007, p. 1) defines legitimate power as “raw power,” invested in a role, such as that of policeman and soldier. Legitimate power is often used as a deterrent to prevent illegal behavior, protect the public interest, and maintain social order.
