There are fears for up to 200 jobs within the Football Association of Ireland, according to SIPTU.
The trade union says it has received information that the FAI is in an “extremely precarious financial situation”.
It is now looking to arrange an urgent meeting with the Minister for Sport Shane Ross to discuss the matter.
SIPTU Sport Sector Organiser, Denis Hynes, says staff are extremely worried about the situation.
“The staff are extremely concerned about revelations that there is a possibility if funding is not found in the next number of weeks that there’s a real risk of the association going into insolvency,” he said.
“That’s a massive concern for us all and the ripple effect and the massive impact that could have in community football is unthinkable.”
