The aim of the study was to gain knowledge about the relationship between employee efforts and different reward areas. Further aim of the study was also to test hypotheses about the employee's experience at work in relation to factors such as gender, age and form of employment. The study was carried out with the support of Johannes Siegrist's effort- and reward model (1996). The study has been quantitative, with 119 employees within the organization answered questionnaires. The questionnaires used was developed by Siegrist (1996). The result showed that the majority of employees experience the effort at work as high and the various reward areas as high. The most rewarding reward for the result was the social reward. With the help of the study, we could conclude that a connection exists between the experienced efforts and some of the received reward within the organization.
