A one-day strike by 500 Bank of Ireland Staff is to go ahead tomorrow morning, after talks at the Labour Relations Commission failed to resolve a row over pensions.
Pickets will be placed on Bank of Ireland's head office in Dublin's Baggot Street and New Ireland Assurance on Dawson Street from 8.30am until 5.30pm.
The Amicus Union, which represents 500 of the bank's 16,000 staff, is planning a further one-day stoppage on 22 November.
Branch banking for customers is not expected to be affected.
Earlier, Bank of Ireland group head of industrial relations, Gerry Mitchell, described the industrial action as premature.
He said the union should have awaited the outcome of last week's Labour Court hearing on the row over pensions before engaging in industrial action.
Mr Mitchell said there was no way the bank could row back from its strategy introduced in October in reducing pension guarantees for new entrants.
He said the move was necessary and would be implemented by companies Europe-wide.
Amicus official Colm Quinlan said tomorrow's protest would highlight the strength of feeling among bank staff about the pension changes introduced by the bank.
