When stress-related diseases are increasing, the preventive work becomes increasingly important. The aim with this essay is to determine established law about psychosocial working environment. With the legal dogmatic method, an investigation has been made about the law on working conditions and what it says about preventive work to the psychosocial working environment. After a profound investigation regarding the frameworks pros and cons, it is possible to draw the conclusion that the law on working environment should keep the character of framework. Even if this entails difficulties with interpretation, it is not suitable to regulate the details in a law that should be appropriate for every profession. By studying the regulations of Swedish Work Environment Authority, the law is clarified. However, they should also clarify the concepts, which the law refers to, in order to know when the law should be applied. The same problem occurs when an analysis is made of the declaration forms of accidents and incidents. As a consequence of a weakly formulated definition of “serious incident”, problems arise when applying the law. How stress-related incidents should be treated is also weakly formulated, which could complicate and delay the preventive work. This is because the employers only know that they should report the diseases but not the incidents.
