The Irish Bank Officials' Association has warned that banking staff face severe job losses over the coming months.
The IBOA wants the Government to put a strategy in place to protect the jobs of thousands of workers in the banking industry.
It said yesterday's announcement by AIB that it is to sell off its Polish subsidiary could lead to the loss of up to 500 jobs here.
AIB announced that it was to sell its 70% stake in Poland's Bank Zachodni to the Spanish bank, Santander, for €3.1bn.
The money will go towards meeting AIB's €7.4bn capital requirement set down by the Financial Regulator.
Larry Broderick, General Secretary of the Irish Bank Officials' Association, said a significant number of back office staff here provide support for AIB's Polish banking operation.
