From the very beginning of humanity, it is human nature to work together as a team. Looking back in history if it weren't for teamwork during wars, people without a plan and a goal would have stormed on to the forefront and many countries without good leadership would not have existed. This thesis deals with the importance of teamwork in institutions for early and preschool education, i.e. kindergartens, primarily dealing with educators, professional associates, other employees as well as principals themselves, but also touches on teamwork among children and parents. Part of this work puts emphasis on the directors of institutions for early and preschool education and what essential characteristics they need to possess in order to be good leaders, all for the purpose of satisfying end users. What is teamwork and what characteristics and competences are important for good, quality teamwork, what are the stages of team formation, and teamwork with possible conflicts, leadership styles, types of communication, communication styles and their advantages and disadvantages are just some of the parts of this thesis. As part of this work, a survey method was conducted (survey among employees in early and pre-school education institutions, i.e. kindergartens) whose results will be presented, compared and processed.
