Some Basic Principles
As the name implies, the Public Service exists to serve the public. Public servants are paid by the public and should serve the public impartially and in a professional manner, irrespective of their own political views or those of the members of the public with whom they are dealing.
On the other hand, the public service has a duty to put into effect the policies of the government of the day. It should also do this in a professional manner, bearing in mind that in a democracy the government may change and the incoming government may have different policies. The public service should implement the new government’s policies loyally and not seek to thwart the government.
