The thesis examines the leadership styles of female leaders in Croatian companies. Through a questionnaire survey of 150 respondents of both genders, whose leaders are female (owners of the companies), the aim was to investigate and present the leadership styles of women in top positions in selected Croatian companies. The results indicated a high perception of female leaders as effective leaders in all five analyzed aspects of leadership: modeling, inspiring, challenging processes, developing relationships, and motivating. When considering differences by respondents' gender, the research did not reveal significant differences between men and women in most aspects of leadership. The only significant difference appeared in the aspect of motivation, where male respondents gave higher ratings than female respondents. When analyzing differences by company size, the research identified statistically significant differences in all aspects, namely in modeling, inspiring, relationship development, challenging processes, and motivating. Female leaders in larger companies were rated as more effective in all aspects of leadership compared to female leaders in smaller and medium-sized companies. Ultimately, the research emphasizes the importance of understanding the various aspects of female leadership and how different variables can influence the perception of these styles. Organizations should support diversity and inclusivity in leadership so that female leaders can apply different aspects of leadership without prejudice or stereotypes that may limit them, thus contributing to the development of effective female leaders in various business contexts.
