Many research studies on the human resources performance of the educational system have proved that pupils/students' educational success depends, to a high degree, on the level of human resource motivation, as well as on their degree of professional satisfaction. Teachers' who show a high level of motivation, both intrinsic and extrinsic, invest more into their activity, are more creative and more efficient in problem solving. The paper debates the results of an empirical study regarding the influence of pre-university teachers' motivation and satisfaction regarding the general work conditions on their work performance by measuring the present motivation and satisfaction level. Furthermore, the determinant factors of their satisfaction with the work place are determined and analyzed. Finally, based on the statistical data process we will conclude and debate on the research hypothesis validation and the empirical model related to motivation - satisfaction - performance interdependences.
