Today, the importance of organizations is increasing day by day. The multiple functions and effects of national and international organizations necessitate new studies/research in the field of organizational culture and organizational behavior. Our primary goal has been to introduce the target audience we aim to address in our book to these new concepts and to prepare the ground for new research to be done. Our book, which aims to provide information to researchers, academicians, decision makers, practitioners, students who are interested in concepts and research in the field of organizational behavior, and to contribute to the national literature, consists of 21 chapters contributed by 28 authors. As can be understood from the subject distribution of the first book of our series, these studies will fill a very important gap in the field of organizational behavior and claim to be a source of new studies. We have completed our book work in a very difficult, troubled and stressful process due to the earthquakes affecting eleven provinces centered in Kahramanmaraş, which is called the disaster of the century in our country. It is admirable that our chapter authors, who were directly affected by these earthquakes, contributed to our book under difficult conditions. For this reason, first of all, I would like to express my thanks and gratitude to all our valuable and expert chapter authors who contributed and supported each other with intense labor, devotion, patience and patience in order to produce this work. In addition, I would like to express my endless thanks and respect to my esteemed teacher Prof. Dr. Mustafa TAŞLIYAN, who honored us by showing us the courtesy of writing a presentation to the book, who has always enlightened my path with his knowledge and experience and who has always been a role model for me, to Özgür Publishing House and its employees who worked meticulously in the preparation of the book for publication, to my family, my esteemed teachers, my friends and you, my esteemed readers, who have supported me in the process of writing the book and have helped me come to this day.
