Opposition Leader Peter Dutton has sworn to repeal laws that will give workers the right to ignore unreasonable out-of-hours communications from their bosses if the Coalition wins the next federal election.

The government agreed to include a "right to disconnect" in its industrial relations bill, which was rushed through the senate last week in a last-minute deal with the Greens and crossbench.

Ignoring suggestions it should be referred to committee for closer scrutiny, or that those amendments should have been circulated publicly, the government has since realised the bill included a mistake that could see bosses face criminal prosecution for contacting employees out of hours.

But Mr Dutton says even corrected, the laws will be damaging to relations between employers and employees, and make the task of restarting productivity growth even more difficult.

"If you think it's okay to outsource your industrial relations or your economic policy to the Greens, which is what the prime minister is doing, then we are going to see a continuation of the productivity problem in our country," Mr Dutton said.

Former Reserve Bank governor Philip Lowe warned last year that generous wage rises to close the inflation gap would only fuel it further unless they were accompanied by increases in productivity.
