Being a member of any sort of group or team in Greece brings with it certain obligations. Firstly, comes the obligation to bring to the group a distinctive contribution which is recognisably your own. Secondly is the obligation to recognise the boss as the leader and guiding spirit of the group.
Thus, teamworking in Greece can be categorized as a group of individuals working on specific tasks, reporting to a central controlling figure. Information would tend to flow more naturally up to the boss rather than laterally to other team members.
