The Arts Council must make its case for funding to the Treasury next year. Government supplies two thirds of its funding, with the remainder coming from National Lottery contributions.
'Everyone at the Arts Council needs to be on message with clients and partners,' said Hastie.
The internal comms post – charged with communicating to 800 staff – was created three years ago when the Arts Council for England merged with the Regional Arts Board, creating one national and nine regional offices.
The offices support more than 1,100 art organisations, local authorities and government bodies.
'The contact we have with other organisations comes from our staff so internal comms is important,' said director of press and public affairs David McNeill.
