The paper starts from the assumption that organisational culture, a type of behaviour considered acceptable by employees (Hofstede and Hofstede 2004), is not pre-extant but is jointly created during the interactions of the people working together. This paper is part of a longer study that has analysed institutional talk in a multinational company based in Romania by looking at different aspects of interaction such as types of questions, modality, mitigation, politeness and frames. The paper tries to identify the uses and functions of humour in the exchanges between the team leader and the team members in this multinational company.
