The article describes the connections between the work ethic, sense of coherence and job satisfaction. Assuming that the work ethic is a system of attitudes and beliefs regarding the professional work and that the sense of coherence is a system of beliefs regarding the entire life, or more precisely, beliefs regarding difficult situations, a regression analysis was carried out in which the two constituents; the sense of coherence and work ethics were predictors of the job satisfaction. The research was carried out by means of the Life Orientation Questionnaire, Multidimensional Work Ethic Profile and Scale of Job Satisfaction and included 300 employees from varied organizations. The multiple hierarchical regression analysis and the analysis of dominance have shown that the essential predictors of job satisfaction are: the sense of meaningfulness, sense of resourcefulness, perception of work as a central value and the valuation of hard work. The above studies suggest that the connected with each other - and being the source of one’s well-being – the sense of coherence and work ethic are the source of job satisfaction.
