Enlargement posed a serious challenge for the European Commission, which set as a goal bringing on board thousands of new staff. How successful was the Commission in meeting this challenge? And how successful were the newcomers in integrating in to the organization? Now, after several years, can we see that the staff from Central and East European countries have had an impact on the organization? Answering these questions sheds new light on the evolution of the Commission’s organizational culture which Ban, author of the new book analyzing these questions, will discuss. LUNCH WILL BE PROVIDED. RSVPs to euce@pitt.edu appreciated.
