European Civil Servants must faithfully serve the European Union and the European Union alone: they must carry out their duties and conduct themselves solely with the interests of the Communities in mind. They shall neither seek nor take instructions from any government, authority, organization or person outside their institution (Staff Regulations, Article 11).

From this it may be gathered that if you are an E.U. civil servant then you must forget about any loyalty to your Queen and country or the population thereof - the only loyalty permitted (by contract of employment) is to the E.U. itself.
It gets worse:

1. 'Officials [and other servants] … shall at all times be at the disposal of their institution' (Article 55). They shall observe official working hours, the normal working week, and arrangements for leave, and may not absent themselves from work without permission or justification.

2. That provision enables Parliament, because of the exigencies of the service and within the limits laid down in Article 56 of the Staff Regulations, to ask officials to work overtime, recall them from annual leave, or cancel the leave authorisation granted.

3. To provide a more effective guarantee that officials and other servants will comply with their duty to be constantly at the disposal of their institution, the Staff Regulations have also introduced a residence obligation, namely: officials [and other servants] shall reside either in the place where they are employed or at no greater distance therefrom as is compatible with the proper performance of their duties (Article 20).

Good grief!
