A report on pay rates in RTÉ has found there is on average a 4% pay disparity in the organisation in favour of men.
That figure is below the national average of around 14%.
Earlier this year, the former head of the Workplace Relations Commission, Kieran Mulvey, was commissioned to carry out a review of role and gender equality at RTÉ.
The review will also find that RTÉ is ahead of other similar enterprises in terms of gender pay and representation.
It looks at full-time staff in RTÉ, full-time equivalent staff and people on employment contracts.
However, it does not include people who deal with the organisation on a limited company basis.
It is understood the report will also make recommendations around transparency and a streamlining of grades within the organisation.
Unions were briefed on the document this morning and staff were briefed this afternoon, when the document was published.
NUJ calls for 'root-and-branch' review of employment practices
The Irish Secretary of the National Union of Journalists Séamus Dooley has called for a root-and-branch review of employment practices and procedures in RTÉ following the publication of the Mulvey report into the gender pay gap in the organisation.
The union says that, through no fault of Mr Mulvey, the report does not give a "full picture" of the situation in RTÉ.
He said: "This was a wasted opportunity because of the limited terms of references, which excluded examination of those engaged on self-employed contracts or engaged through external companies.
"RTÉ requires many journalists to accept self-employed contracts, others are allowed to establish companies and are represented by agents.
"You cannot comprehensively review employment in RTÉ by looking only at those on employment contracts.
"There is a strong gender dimension to many of the unacceptable practices - for instance only employees are entitled to paid maternity leave."
Speaking on RTÉ's Drivetime, SIPTU economist Marie Sherlock described the findings as "worrying but not unexpected.
She said it is disappointing that the range of employment contracts within the organisation were excluded, as the review looked at full time permament employees only.
Whilst Ms Sherlock welcomed the publishing of today's findings she said she looks forward to a further review which examines those on part-time and temporary contracts.
