We live in a global world characterized of economic internationalization. It imposes new demands on our way of managing our world. The Swedish labour market is not an exception. Critics believe that the Swedish model is in need of change. In the context of posting of workers the interplay between social rights and the freedom of providing services gives birth to problematic fields of social dumping. Both Norway and Sweden face similar challenges on the internal market. Nevertheless, both countries have applied different strategies in their work to counteract social dumping.    This paper aims to compare the Swedish- with the Norwegian model and display how both systems works to prevent social dumping. Further the paper will examine if the Norwegian system with universal collective agreements could be implemented in the Swedish system without creating friction in view of the Swedish model. By using a comparative method with sociology of law the paper brings understanding to the reader for the complex interaction between society and legal systems. This is key to fully grasp why Sweden and Norway has chosen different legal paths.
