For many years, Pakistan's most urgent challenge has been a lack of leadership, and the issue is much more widespread in governmental enterprises than in the private sector. The subject of what makes a good leadership style to increase employee engagement is becoming more and more important in addressing the leadership problem. Therefore, the study's goal is to investigate the fascinating topic of the most practical leadership style and how it could affect workers' motivation. For this reason, employee motivation is the dependent variable, whereas autocratic, democratic, and laissez-faire approaches are regarded as independent variables. Data is gathered from a sample of 110 middle- and senior-level managers employed by WAPDA, an independent organization in Pakistan that is administratively controlled by the federal government for the development of energy resources, using a survey questionnaire based on the closed-ended Multifactor Leadership Questionnaire (MLQ). To assess research hypotheses and determine practical consequences, descriptive statistics, reliability statistics, multiple regression models, and analysis of variance are used. While democratic and laissez-faire leadership styles are shown to positively predict employee motivation, autocratic leadership styles are found to be more dominant and to have a strong negative association with employee motivation. However, it turns out that there is no correlation between democratic leadership and employee engagement, which illustrates the organization's dispersed and bureaucratic structure. The study's findings support the theoretical presumptions for authoritarian and laissez-faire leadership styles, but they contradict those for democratic leadership styles. In the face of a detrimental bureaucratic environment, the article suggests that democratic and laissez-faire leadership styles be preferred. Few studies have examined the connection between leadership styles and worker performance, but very few have examined the bureaucratic environment of developing economies.
