Ulster Bank has said it will close another 14 branches in the Republic of Ireland next year.
37 roles are at risk when the branches close in March.
Ulster Bank said today that the job losses will be "volunteer led" with workers invited to redeploy to other areas in the bank.
The latest closures are part of an announcement made last year to reduce the number of branches from 214 to between 175 and 185 on the island of Ireland.
Another 10 branches are also to close in the North early next year.
After the March branch closures, Ulster Bank said it will have 111 branches in the Republic of Ireland and it said it does not expect to close any more branches next year.
It said the decision to close any branch is made on a case-by-case basis, based on local information.
"Banking has changed significantly over the last few years as more and more of our customers are using digital technology to bank with us where and when it is convenient for them. As a result, only 13% of transactions happen in branches in the Republic of Ireland," the bank said in a statement.
"We continue to invest in a range of channels to respond to how our customers prefer to do their banking," the statement added.
The branches to close are located in Athboy, Co Meath; Ballinrobe, Co Mayo; Ashbourne, Co Meath; Athy, Co Kildare; Castleblaney, Co Monaghan; Castlerea, Co Roscommon; Clones, Co Monaghan; Croom, Co Limerick; Ferbane, Co Offaly; Loughrea, Co Galway; Manorhamilton, Co Leitrim; Moville, Co Donegal; Roscrea, Co Tipperary and Wicklow town in Co Wicklow.
Ulster Bank said it had written to customers in the affected branches and said it was also "communicating directly with staff" in the branches.
The Finance union, IBOA, said it was "very disappointed" at today's news from Ulster Bank.
The union has asked Ulster Bank management to review its latest decision to close more branches in the interests of both its customers and its employees.
It also pointed out that the bank has now returned to profitability with positive results in each of the first three quarters of this year.
Apart from raising issues about the alternative arrangements to be put in place for customers in the affected areas, the union is also seeking immediate confirmation from management that the latest tranche of closures will be the last for the foreseeable future.
"While IBOA is continuing in talks with management on a comprehensive agreement on future change within Ulster Bank, we need greater clarity from management about its future intentions to ensure that the outcome of these negotiations offers the best possible solution for all of the bank’s stake-holders - including staff and customers," commented the IBOA's general secretary Larry Broderick.
