This is a study of an ethnic hierarchical division of labor on Iföverken in the south of Sweden between 1895-1930. The study aims to see if migrants got different kind of profession at Iföverken and if there were in fact ethnic hierarchical distribution of work. It also aims to see if the pattern of ethnic hierarchical division of labor was different before and after the First World War. Also, the study aims to see in what regard these labor migrants became members of the local union, division 227. By studying if labor migrants got different kind of professions using the concept of class in a structuralist perspective, hierarchical positions become visible. Using moving in and out records that the priests wrote as migrants arrived and member list of the union as the main sources, the study shows that there existed a pattern of ethnic hierarchical division of labor. The results show that migrants from regions with Slavic population got the most unskilled work while migrants from regions with German population made most of the professional and higher valued workforce. There where some migrants that became active members of the union division 227, consequently it can be argued that these migrants where a part of a collective movement and class struggle.
