I am not aware of any proposal being considered by the Department of Public Expenditure & Reform to introduce name badges for Civil Servants whose official functions entail direct dealings with members of the public and it is not something I am considering for staff at my Department.
It is my Department's policy that all officials when dealing with members of the public over the phone or in person, give their name and contact details. In relation to written correspondence, officials are required to print their name and contact details at the end of letters in order that the addressee can contact them in the event they need to clarify any aspect of the letter.
