Greens Deputy Leader Adam Bandt says the business and government push on minimum wages and penalty rates is likely to fail in the Senate after the next election.
Responding to reports of a renewed IR push by business leader, Mr Bandt, the Greens spokesperson on industrial relations, said the Greens would block any moves to cut minimum wages or penalty rates before or after the next election.
"The minimum wage should be increased not cut," Mr Bandt said.
"Big business can jaw-bone as much as they like but the next Senate is likely to block any moves, especially if the Greens hold the balance of power."
"It is becoming clearer by the day that the next election will be fought on industrial relations. If that happens, even if Tony Abbott scrapes back in the Senate will stand in his way."
