Royal Bank of Scotland, which owns Ulster Bank, has made 221 people redundant at its Dublin Technology Services Centre.
A spokesperson for CIO 100 ranked RBS said that the roles based in Ireland were “no longer required".
RBS's Dublin-based Technology Services Centre is due to close later this year, resulting in the loss of 196 jobs, while 25 technology services staff will also be laid off at RBS’s Belfast office. The cuts will be phased, starting from July 2010.
The bank said that some of the roles will be transferred to locations where RBS has key back office hubs in the UK and elsewhere.
“We will offer redundancy terms and, where possible, opportunities for redeployment,” the spokesperson said. “It is our intention to ensure that the number of compulsory redundancies is kept to a minimum.”
The union Irish Bank Officials Association’s (IBOA) General Secretary, Larry Broderick, met with staff on Tuesday and has asked RBS to review its position and to engage with the union.
“It is clear that unless RBS provides alternative IT job opportunities in Ireland, these redundancies will be compulsory," he said.
“Since RBS received substantial incentives to set up its operations in Ireland, it is not acceptable that they can just walk away and abandon these highly skilled and committed staff."
He added: "Given the Irish Government's stated position that technology jobs are key to the future of the Irish economy, we are calling on the Minister for Enterprise, Trade and Employment to make representations to the British Government, which now owns 84% of RBS, to seek to retain these IT jobs in Ireland."
Broderick said that IBOA and RBS will be undertaking negations in the coming weeks.
Last year, RBS announced that it would cut 4,500 UK jobs, revealing in May 2009 that up to 700 of these would be IT jobs.
