Relationships in the organization are an integral part of every employee's working day. The relationship with coworkers is a fundamental factor of communication in the organization, the relationship with the supervisor is an important factor in the quality of the work done, and the relationship with the organization is a key factor for the successful operation of the organization itself. All three components of relations in the organization affect the experience of the workplace, as well as the job satisfaction and life satisfaction of the employees. The aim of this research was to examine relationship between relations in organization (relationship with coworkers, supervisor and organization), job satisfaction and life satisfaction. The sample included 247 employees of which 158 were female and 89 men. To measure relationship in organization was used Scale of Worker Relations (Biggs, Swailes i Baker, 2016), for measuring job satisfaction Index of Job Satisfaction (IJS) (Brayfield i Rothe, 1951) was used and to measure life satisfaction was used Satisfaction with life scale (Diener, Emmons, Larsen i Griffin, 1985) The results have shown that there is positive correlation between relationship with coworkers, supervisor and organization with job satisfaction and life satisfaction whereby the relationship with supervisor was shown to be the most significant predictor of job satisfaction. The relationship with the supervisor and the organization showed to be a significant predictors of life satisfaction, while the relationship with coworkers did not prove to be a significant predictor of life satisfaction.
