This study presents a part of a postdoctoral research that deals with the levels of job satisfaction of Greek teachers. At first, the concept of professional satisfaction and its significance were elucidated. Emphasis was given on the relation between this concept and its impact on teachers’ self esteem. On the whole, Greek teachers are satisfied with many aspects of their profession even though some differentiations were observed in relation with the recognition they enjoy from the society. Also, some significant differentiations were observed in relation with the gender and their marital status.
