Ulster Bank is to cut 110 jobs at its mortgage centres here. 80 of the positions will go from its branch in Sandyford in Dublin, while the rest will be lost from offices in Belfast.
The bank says it is outsourcing the managing of its mortgage arrears to Scotland.
Staff affected work in the Retail Problem Debt Management Unit, and are involved in mortgage arrears negotiation.
General -Secretary of the IBOA, Larry Broderick, has said "We are concerned that units based overseas may not be as attentive or understanding of the needs of customers experiencing significant difficulties with their mortgages".
"Outsourcing has not always delivered for Ulster Bank’s customers. They will not easily forget the meltdown on the Bank's outsourced IT systems in the summer of 2012" he continued.
"IBOA is aware that RBS Group is conducting a major review of Ulster Bank’s operations. So we have asked Ulster Bank management to defer any decision on the mortgage arrears unit until RBS completes its review" he added.
The IBOA has written to its members in Ulster Bank, outlining potential scenarios that could lead to many hundreds more jobs being stripped.
The Ulster Bank parent company, RBS, has previously said it would close between 30 and 40 branches in the Republic and Northern Ireland by the end of 2014.
