ground of the Study Power has been a debate of many scholars in the field of management, organizational behavior since 1959 and has been practiced in different geographical settings. As a result, different conceptualization and definitions have been given by several philosophers, politicians, and scholars for the last decades. Scholars classify this flexible concept in many ways. One concise way to classify the different sources of a person's power is to classify as either primarily personal or organizational (Goethals, Sorenson & Burns, 2004). Besides, French and Raven also classify power bases as reward, legitimate, coercive, information, expert and referent power. A manager's reward power, coercive power, information power and legitimate power would be more strongly derived from the organization, while expert and referent power would be more personally based. All the above source of powers plays an important role in influencing teachers' job satisfaction (Afza, 2005; Lee & Low, 2008; Nedaee, Alavi, & Ramezani, 2012). `Therefore, understanding how power affects teachers' job satisfaction and student achievement will allow school principals to change or maintain their power bases and to achieve desirable outcomes. Job satisfaction on the other hand, equally plays a great role to produce knowledgeable, skilled and competent students in educational sectors. Similar to power, it has been an issue of concern for many researchers in the past, mostly because of its link with significant organizational phenomena, such as turnover, absenteeism, productivity, career mobility and organizational effectiveness (Nguni, Sleegers & Denessen, 2006). As indicated by Spetor (2006), job satisfaction is the most repeatedly inspected variable (Spector, 2008). It has been treated regularly because attitudes and emotional state affect the employees' behavior and, thus, possibly lead to the organization's successes or failures. Therefore, improving the performance of schools will not yield any result if teacher's job satisfaction is ignored. This is because satisfied employees perform better and become more efficient and productive since they are likely to be absent less, show less job stress, stay at work longer. Therefore, examining the nexus between principals' power bases and teachers' job satisfaction is important and timely. 1.2. Problem Statement School principals as educational leaders are required to mobilize the abilities and efforts of the teaching staff to provide an effective educational program. To accomplish this, school principals should have the power to fulfill teachers' job satisfaction and organizational outcomes (Bal, et al., 2008).For this reason, school principals need to understand how power is acquired, know how and when to use it, and be able to anticipate its probable effects. As indicated by Nelson and Quick (2012), the concepts of power and leadership are closely linked. Leaders use power as a means of attaining group goals. In addition, by understanding how power functions in organizations, principals will...
