The purpose of this thesis is to examine the relationship between librarians and library support staff in public libraries regarding status, distribution of work and working climate. We were interested to know if there is a conflict between the two occupational groups and how it can be explained. We also wanted to learn what the future holds for the library in terms of professional categories and tasks according to library staff of today. This study is based on twelve qualitative interviews with four heads of libraries, four librarians and four library assistants. Three theoretical approaches were used in the analysis of the interview material: professionalization strategies, conflict theories and theories from group psychology.
