AIB employees have voted to accept pay proposals negotiated under the auspices of the Workplace Relations Commission.
AIB workers, who are members of the Financial Services Union, will receive salary increases worth 2.2% on average.
The senior industrial relations officer at the Financial Services Union, Billy Barrett, said that while the pay increase comes after a lengthy engagement between the union and AIB, a number of important pay-related matters still require attention.
"We need a structure of remuneration and reward in AIB that recognises the rapidly changing environment within the financial services sector," Mr Barrett said.
The Financial Services Union's General Secretary, Larry Broderick, said the pay deal in AIB follows a number of similar agreements achieved by the union recently in other companies in the financial services sector.
"As well as earlier pay rises in the major retail banks, our members in the technology services companies like Wipro and Infosys have also recently balloted to accept salary increases worth 2% on average," he said.
Talks are continuing in a number of others, he added.
