UK, non-government public sector, very senior people still have secretaries - often described as personal assistants. The PAs handle interfacing and information flow, the senior people can get on with the thinking.
A PA is not a secretary years ago I worked on organising a large event and one of the committee member was the PA to the county fire chief.
She was awesome, at the first meeting she had worked out from previous years all the key things the other members of the committee needed to do - written all the letters and handed them to us to sign.
