Members of the National Union of Journalists (NUJ) in RTÉ have voted no confidence in RTÉ's New Direction Strategy.
The result of a ballot showed members voted no confidence by a margin of 89% on a 35% turnout.
The NUJ opened the ballot over what it described as "grave concerns" about the outsourcing of the production of programmes as part of RTÉ's future strategy.
"We have no confidence in and do not support the strategy currently being pursued by RTÉ and call on management and Government to cease its implementation," the NUJ motion stated.
Last month, SIPTU members in RTÉ voted no confidence in the management plan, which the union said would result in the endless outsourcing of jobs and deal a fatal blow to public service broadcasting.
RTÉ said it believes that the five-year strategy, now in its second year of implementation, offers the best way forward to secure the future of Ireland's national public service media and give more to Irish audiences in a much changed media landscape and with rapidly evolving audience habits.
"This strategy was published following extensive consultation with the public, RTÉ staff and a wider group of stakeholders," an RTÉ spokesperson said.
"The vast majority of staff supported the need for RTÉ to evolve as outlined in the strategy during this consultation process.
"We continue to remain available to meet with the unions, as we have done, to progress these and other relevant issues," they added.
