Staff at the FAI are seeking an urgent meeting with management and the Government following the revelations about the association's finances.
The FAI said there will be consequences because of the €55 million in liabilities but that staff at the association would be the first to know about it.
However, they ruled out any impact on the international men's and women's teams
SIPTU said FAI workers are extremely concerned and want clarity on what it means for those who work at grassroots level in football.
A former FAI chief executive said the association could be facing five years of austerity.
'This is truly heartbreaking for the thousands of people who play and are involved in Irish football...that this is what the hierarchy has been overseeing for the past 10, 12, 14 years. And heartbreaking for the FAI staff and their families' pic.twitter.com/kRWnnFW0WH— RTÉ Soccer (@RTEsoccer) December 6, 2019
Bernard O'Byrne said the level of debt suggest that there will have to be cuts to job and spending at the association.
The Minister for Sport Shane Ross has repeated that State funding will not be restored until there is a complete change at the top of the FAI.
Mr Ross described the situation as a "complete and utter mess" and he said it looks like the FAI is on "life support" from UEFA.
He said he was keen to resume the €2.9m in Government funding to the FAI but that it would have to see what plan the FAI have to get out of the current situation.
Prof Niamh Brennan of the UCD Centre for Corporate Governance said the FAI was "hanging by a thread" and unless it got help from the banks and elsewhere she could not see how it could go on.
The body representing players said the game will continue to suffer unless there is complete change at the top of the FAI.
Shane Supple of the Professional Footballers Association of Ireland said its members were shocked by the revelations about the FAI finances and described it as a lost opportunity for football in this country.
