Howlin warns of tougher new Croke Park deal
Mr Howlin said it will be looking for more productivity from public sector workers and other ways to reduce costs.
But there are unlikely to be pay cuts as it tries to squeeze the public sector for more productivity and find other ways to reduce the pay bill.
Mr Howlin said the public service pay and pensions bill would need to make "a substantial contribution" to meeting financial challenges ahead
Additional productivity and cost extraction measures that were not envisaged under the current Croke Park deal would be required, the minister warned.
