The purpose of this study was to research the level of satisfaction teachers received from communication within their working environment, their sense of the effectiveness of the institution itself, as well as the relationship between these factors. A quantitative method was used in the study. A total of 296 questionnaires were answered by teachers aged 25–64. Statistical analysis of the data was performed using the statistical software SPSS, while for the implementation of the statistical tests we applied the independent-samples T-test parametric, as well as one-way ANOVA, Kruskal–Wallis, and Mann–Whitney parametric statistical criteria. According to the results, the teachers showed high levels of satisfaction with the communication related to their feedback and believed that both parents and the local community do not participate actively in the school life. The development of an effective communication system within an educational institution can potentially become the driving force for effective functioning. The study complements the existing research on communication as a factor in the effectiveness of an educational organization. It highlights the dynamics of the teachers’ association to the greatest possible extent, attempting to link the communication factor to all aspects of school effectiveness.

The present study examines teachers’ perceptions regarding moral satisfaction, financial gain and professional motivation in order to examine the relationship between these factors and their work efficiency. The degree of agreement and disagreement in the perceptions of 270 Primary Education teachers, regarding the extent to which their effectiveness at work is affected by the existence of the above factors, is studied, and the study was conducted in 31 primary schools in Greece. The size of the sample and the way the results are extracted is a key innovation of the research, as for the first time, the above concepts are quantified through the answers of those involved in education. Their answers are examined by the method of quantitative research and the statistical program IBM-SPSS 24. It appears that moral rewards, the relationship with their manager and colleagues and their degree of self-esteem are elements that, if increased and positive, lead to higher productivity in their work. The recognition of the overall offer of the teachers by colleagues, the manager, society and the state have a positive effect on the effectiveness of their work, while its lack reduces their motivation to be efficient.
