Despite findings in the literature on its significance, the acclimatization of teachers into school units is not well organized. Hence, many newly appointed teachers fell as a “foreign body” into school, they do not interact with the other members of staff and they are not actively engaged in school life. This study aims to explore the factors involved in social behavior (collegial relations) among members of the educational community. These factors may affect the acclimatization/reception of teachers who, regardless of their teaching experience, are called to teach for the first time in a new school environment. According to the findings, it is essential the attitudes of teaching staff, in matters of cooperation, to be transformed and a collegial climate in schools to be established. To this end, fostering empathy among teachers through educational activities and enhancing opportunities for cooperation and teamwork inside and outside the classroom would be of significant contribution.
