The Irish Congress of Trade Unions has withdrawn from a proposed forum to address ongoing issues in the film industry.
The move follows revelations from RTÉ's Prime Time, on the activities of the Irish Film Workers Association.
Several senior figures in the industry claimed that a faction within the organisation was responsible for widespread intimidation and threatening behaviour of workers.
In a statement to RTÉ's Prime Time, ICTU said it, 'will only sit on a forum of workers represented by legitimate trade unions'.

It is understood that SIPTU and other unions have also informed Screen Ireland [formerly the Irish Film Board], which was setting up the forum, that it will not attend if the Irish Film Workers Association is present.
The Prime Time programme also revealed how some productions were being forced to employ members of the group to avoid industrial unrest and wildcat pickets outside film studios.
In a statement Screen Ireland said it was continuing to address the recommendation of an Oireachtas Committee to hold an industry forum.
Screen Ireland said: "The Oireachtas committee recommendation was that we should convene a meeting in order to allow all stakeholders within the sector to meet and work together to develop mutually beneficial solutions for the industry.
"The implementation of this recommendation is proving challenging given the context of the revelations in the recently broadcast RTÉ Prime Time programme, which focused on bullying and harassment in the film and television industry.
"We are continuing to work on the organisation of this event and we hope to be making an announcement in the near future."
