Public Expenditure and Reform Minister Brendan Howlin is warning that time is running out on reaching an agreement to resume the public-sector pay talks.
Labour Relations Commission chief executive Kieran Mulvey has been given until next Monday to assess if there is a basis to re-enter negotiations on Croke Park 2.
Mr Mulvey has already held 35 meetings with trade union leaders over the last two weeks.
Minister Howlin said that he accepts that the LRC's task of brokering an agreement on pay bill savings is challenging, complex and difficult.
"We need to make the economic savings to save €300m this year," he said.
"So there is a finite amount of time available to us.,
"He has asked for the additional number of days until Monday, and I'm not going to be prescriptive beyond that, but the Government is going to have to start making its own decisions if there isn't an agreement."
