Purpose The aim is to study how the staff members in a bank perceive a company culture and how this perception is related to background aspects (gender, age, etc.), and engagement in regular regulating activities decided by the company. Design and methodology A abductive approach inspired by action-, adult developmental-, complexity- and holon theory comprise a frame of reference applied on a multi methodological case study in progress , within which a survey distributed in the whole bank in Sweden has been analyzed in terms mainly of a multiple linear regression analyze.. Findings Results indicate strong integration in the company culture related to active engagements in regular and regulating activities. The regression analysis clearly indicates that the cultural integration is more influenced by those activities than by individual background variables. However, results also show more critical attitudes towards the culture. This may reflect both an individual developmental aspect and a generational aspect. Research limitations.
