The purpose of this study is to examine if the Swedish syndicalist movement SAC´s ideology also is able to function as a worldview. Worldview is a contested concept and the meaning may shift depending on who you are talking to or what study you are reading. Therefore, I aim to create a deeper understanding of the concept of worldview in our time with this study. The material is a booklet from SAC that explains their ideology and trade union work. I will analyse the material through a qualitative content analysis combined with Stenmark and Franck´s (2016) worldview definition as a theory. The research questions for this study are based on Stenmark and Franck´s (2016) worldview definition, which of the smaller worldview components are possible to find in the material? And given the answer to research question 1, to what extent can SAC´s ideology and union work be understood as a worldview based on Stenmark and Franck´s definition? The study concludes that SAC´s ideology and trade union work are able to function as a worldview. Several of the main components of a worldview is present in the material like SAC´s view of soceity and central valuation system among others. The description of how a worldview functions allows the ideology to be seen as a worldview.
