The Labour Court is due to begin hearings today into the dispute over the introduction of a new pension scheme at Bank of Ireland.
The bank has decided to close off its defined benefit scheme to all new staff and instead offer them a new "hybrid" pension.
Unions are vehemently opposed to the move, which they say will create a two-tier system.
Five hundred members of the Amicus trade union are already planning industrial action in the coming weeks.
However, the IBOA, which represents around 8,000 BoI staff, has decided to hold off of any strike plans pending the outcome of the Labour Court case.
