Members of the National Union of Journalists (NUJ) in RTÉ are being asked to vote on whether they have confidence in RTÉ's New Direction Strategy.
The NUJ said it has grave concerns about the outsourcing of the production of programmes as part of the plans.
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.
A ballot of NUJ members opened today and will close next week.
The union said the cancellation of programmes such as Upfront with Katie Hannon, the closure of RTÉ's TV documentary unit, the closure of the religious programming department, and plans to hand The Late Late Show and Fair City programmes to private companies, have all given rise to grave concerns.
The NUJ said it is opposed to the privatisation of core functions of RTÉ, and called for adequate public funding, delivered via a sustainable funding model, to support a strong, vibrant, independent public service media.
"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 states.
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," a 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."
