Motivation is an essential impetus in peoples lives. This is true for any sphere of life, but especially for a professional work environment. The paper at hand examines motivation in the professional life and focuses particularly on the motivating factors and sources of motivation for teachers.Definitions of the term motivation will be provided based on an extensive literature research and concepts of motivation theories will be explained. In addition to this, various sources of motivation will be considered and current empirical studies covering teachers motivations will be introduced.The empirical part of this thesis aims at answering the following research question: Which motivating factors are important from a teachers point of view? In order to answer this question a group discussion with six teachers of various experience levels was held. The discussion was later evaluated using the qualitative method of inductive classification by Mayring (2015).Insights gained through this analysis show an expansion of motivational research by the factor school. The results imply a high public status of teachers, which thus constitutes a relevant factor for the motivation of teachers. Additionally, the dependence on the system school as well as societys demands on schools are considered important for motivation. Based on these results, it is necessary to improve the image of teachers, to enable them to participate and to appreciate their work.
