In this work, the impact of a manager’s business ethics upon employee satisfaction is being studied.Satisfaction is one of the main representatives of a company’s success and its businesses. Business ethics is closely related to satisfaction itself, so this analysis examines mutual impact and correlations. Ethics, which represents the concept of good and bad in this living, differs from business ethics which is based on the behavioural codex of private entities in work relations, in the matter of fact represents an accurate model of behaviour on micro, meso, macro or global standards. Since employees' satisfaction itself has a great impact on individuals and this on the entire company, it began to be a subject of studying during the thirties of the previous century. Job satisfaction represents an employee's personal attitude towards work he performs, as well as towards physical, organizational and social conditions at the workplace, including rewards he receives for successfully terminated tasks. In order to confirm 4 set hypotheses which show direct dependance of employee’s satisfaction on company’s business ethics, a detailed analysis of the survey was carried out. The problem we face consists of business ethics still not being implemented in some places. Since the manager deals with work organization, public clients and employee relations, it is very important how he behaves and towards whom. Manager always must be an example and act in accordance with ethics degree. This results in an increase of employee satisfaction and ultimately determines overall progress of the entire establishment. With this research, by performing an exploratory factor analysis in order to obtain measurement scales, Cronbach’s Alpha coefficient confirmed the validity of correlation. After scales were determinated, they were correlated and ANOVA test was performed to confirm homogeneity of variance. Since all 4 hypotheses were not rejected, the thesis concluded that business ethics has a significant impact on employee satisfaction was concluded.
