Sinn Féin has acknowledged it could take until 2021 to reverse all public sector pay cuts
Sinn Féin says the Lansdowne Road pay agreement is dead and the Government needs to negotiate a new one.
The party has outlined a proposal to reach a new agreement with public sector workers - but admits it could take until 2021 to reverse all pay cuts.
The Lansdowne Road Agreement is due to be in place until September 2018.
The Cabinet has been discussing the issue of public sector pay today as pressure mounts on government to begin talks on a replacement for the current deal.
Several prominent unions have said the deal should be reconsidered in light of the deal reached with gardaí earlier this month, which the GRA and AGSI are currently balloting members on.
Ministers have insisted the deal is within the framework of Lansdowne Road.
Sinn Féin's Public Expeniture spokesperson, David Cullinane, says the issue has to be dealt with now.
Deputy Cullinane said: "It's not just us saying it - IMPACT are saying it, the Irish Congress of Trade Unions are saying it, SIPTU are saying it.
"We've met them. We have been very clear to them that we don't believe all of their demands can be met. There needs to be a framework and there needs to be clear principles which would underpin such an agreement," he said.
Fianna Fáil's public expenditure spokesperson Dara Calleary says the minority government has been on the back foot when it comes to dealing with the issue of pay.
"I think what the Government needs to do - and we hope to get a signal today - [is] actually take leadership in relation to the public service pay debate," he suggested.
