The three significant predictors of job satisfaction in structural empowerment were resources, support, as well as informal power. Loretta (2011) reported that middle managers authorized to obtain more resources would be seen as more effective leadership to front-line nurses, which lead to the nurses also getting more resources, thereby enhancing the quality of care. Respondents who perceived themselves gaining support from managers showed increased job satisfaction. According to Manojlovich (2003), support from their organization can ensure nurses with creative solutions to care issues, and enable them to demonstrate higher performance. In order to improve nurses' work satisfaction, managers should support the work of nurses, concern about their clinical work, and provide effective advice and recommendations to help them to maximize their performance. In this study, informal power had an impact on each dimensions of job satisfaction. However, respondents felt less informal power than the nurses in other studies (Laschinger, Wong, & Greco, 2006).
