The National Union of Journalists has launched a campaign aimed at securing Government support for RTÉ.
It is the first stage in the campaign supported by sister unions SIPTU, Connect and the Irish Congress of Trade Unions.
Michelle Stanistreet, General Secretary of the NUJ, said a slogan for the campaign will be used by the unions to highlight the role played by RTÉ as Ireland's public service broadcaster.
The slogan is 'It's Your RTÉ, Save It' and, in Irish, 'Leatsa é RTÉ, Sábháil é'.
The NUJ says it is intended to drive home the message that RTÉ belongs to the people of Ireland and must be saved in the public interest.
Michelle Stanistreet said: "The message of the campaign is simple: 'Public Service Broadcasting is worth saving'. The consequences of a diminished RTÉ would be the diminution of Irish culture in all its rich diversity."
Séamus Dooley, Irish Secretary of the NUJ, said: "There is a financial crisis in RTÉ and both An Taoiseach and the Minister for Communications, Climate Action and Environment must give leadership on this issue.
"We are not looking for a hand out, merely demanding that the Government honour its commitment to public service broadcasting and to the Irish people."
