Stress, besides resulting from personal and organisational reasons, is a factor that affects working performance of individuals under all circumstances. Especially the bank employees, who work in service sector and in close relationship with people,are stressed due to personal reasons and meanwhile organisational reasons also affect their stress levels considerably. In this study, the purpose is to ascertain the connection between organisational stress factors that affect the working perfor- mance of bank employees negatively, and gender and education level of emplo- yees, to determine the relationship between the satisfaction level and gender and educational level and to find out if there is a differentiation in the employees’ satisfaction and stress levels in terms of the type (trade bank, participation bank) of the bank. In line with these purposes, surveys are conducted in August and September 2009 to 110 people in total, 62 people in five branches of a trade bank and 48 people in six branches of a participation bank, both are located in Konya. The stress and satisfaction levels of the people who have participated in the survey study are averaged and after analyses, the results are evaluated statistically.
