The aim of this master’s thesis is to identify differences and similarities, regarding security, in two goods terminals in an organisation in the transport and goods sector. In this thesis we use Cultural Theory as an analytical instrument to investigate organizational culture, as seen from a security perspective. Cultural Theory is a theory seen from two perspectives, the stable perspective and the mobile perspective. These two perspectives concentrate on different research areas. In the thesis we choose to present two representations of both perspectives. A case study was designed to collect the empirical material. Interviews were held, both with individuals and with focus groups at both terminals. The two perspectives of Cultural Theory were also implemented when we collected our material. Our analysis of the empirical material, made from the representations of the stable- and mobility perspectives of Cultural Theory, shows that both terminals have tendencies towards a hierarchical bias, but the terminal named B shows a somewhat higher degree of group – level than the terminal named A. We propose that the size of the terminals and the relationships between the employees can make a difference and can explain the higher degree of group level in terminal B, but the result of this thesis can not entirely confirm this. An analysis of factors that affect violations also shows that terminal A has a higher potential risk of fiddling than terminal B. This conclusion is also a topic that needs further research if it is to be confirmed. / Uppsatsnivå: D
