Presenter Carolyn Ban Abstract This paper reports on the results of an in-depth study of the arrival of staff from the countries of Central and Eastern Europe as a result of the enlargements of 2004 and 2007. Based on extensive interviews both within the Commission and in six of the new member states, it finds that the Commission has succeeded in bringing in a large number of new staff (equal to 20 percent of their pre-enlargement staff) and integrating them into the organization. But when one looks at managers, one finds that, contrary to previous research, national culture is less useful in explaining differences in management approach than had been expected, based on previous research. This paper explores some of the reasons why this is the case.
