Bank staff have threatened industrial action if further pay cuts are imposed.
However, the Irish Bank Officials' Association has given assurances that the public would not be hit.
It said the action, if approved by its members, would take the form of non-cooperation with proposed re-structuring plans within the banks.
IBOA members will debate a motion on industrial action at its biennial delegate conference which begins today.
Speaking on RTÉ’s News at One, IBOA General Secretary Larry Broderick said further pay cuts would be a "bridge too far" for bank workers.
Mr Broderick said his members had taken "considerable pain" over the past four or five years, and they could take no more.
He also criticised the Government for effectively endorsing pay increases for high level bank executives, while "coming after" his members.
"It is absolutely outrageous to think the Government - a major shareholder right across the industry - sits on the benches and gives an acknowledgement to senior executives that they should have pay increases, and even have the temerity to suggest that our members should take a pay cut.
"I think anybody would see that as a nonsensical position."
