SIPTU says it is re-evaluating its campaign for pay rises for its members employed in the private sector due to the sharp increase in the cost of living.

The country's largest trade union says rising prices are particularly impacting lower paid workers.

SIPTU Deputy General Secretary Gerry McCormack said gains that workers had made from previous pay rises are being wiped out.

"We will be considering what rates of pay increase we will now be pursuing, as well as the possibility of front loading and shorter terms of duration for agreements," he said.

"In the coming weeks we will be seeking to ensure that in companies that are profitable our members get their fair share for the efforts they put in," he added.

Speaking on RTÉ's News at One programme, Mr McCormack said they will be asking their officials to seek as much of an increase as possible when bargaining with employers.

"Where we already have agreements in place - were are going to ask our officials to review those to see if it's possible to increase them," Mr McCormack said.

He said lower paid workers are being particularly impacted by inflation.

"Those people on low pay, people on minimum wage, people on fixed incomes, those people are going to be really badly hit by inflation."

In December, private sector unions said employees should seek pay increases of between 2.5% and 4.5% during 2022.

The Private Sector Committee of ICTU and the Nevin Economic and Research Institute said such claims were justified on the basis of expected strong and rapid economic growth.
