PTSB and its group of unions, FSU, Mandate and Unite, have agreed a pay deal for 2026.
The proposals include a 4% pay increase for 95% of staff divided evenly between a general increase and performance model.
The deal also involves the introduction of a new grade which is linked with professional financial advisor qualifications (APA/QFA).
This will result in once-off, base salary uplifts for APA and QFA qualifications which will increase to €3,000 and €1,000 respectively.
The agreement also includes a commitment for all parties to engage on a variable pay scheme during 2026.
"We welcome the acceptance of the 2026 Pay Agreement this week following robust and collaborative engagement between the Bank and its Group of Unions, and we look forward to continuing this into the future," said PTSB Head of People, Karen Hackett.
Unite Regional Officer, Jean O'Dowd, described the new pay deal as welcome news for members at a time of ongoing cost-of-living pressures.
Senior Industrial Relations Officer with the FSU, Billy Barrett, said the deal will mean a 4% pay increase, for the majority of its members.
"It is important any pay increases in the retail banking sector are above inflation and take account of the rising cost of living," Mr Barrett said.
Divisional Organiser with Mandate John O'Donnell said this is the second year in a row where positive and progressive change to internal policies had been successfully negotiated.
"Our members acceptance of this proposal shows their support to the work we are doing within PTSB and their support of the Group of Unions model adapted earlier this year," Mr O'Donnell said.
