Liberal backbenchers are urging the government not to back down on its industrial relations agenda and push through a union-busting bill to spur economic growth after the coronavirus pandemic.

Senator Andrew Bragg and MP Jason Falinski argue the government should not lose sight of its pre-crisis industrial reform agenda and go further to ensure the employers have the flexibility to respond to future crises.

Prime Minister Scott Morrison has signalled in recent days he is considering broad industrial reform but also wants to keep working with the unions as Attorney General Christian Porter did in negotiating the ACTU's support for the JobKeeper scheme.

Senator Bragg said the government's first priority in the industrial arena should be passing its Ensuring Integrity bill, which will allow the government to deregister unions that break the law, including by leading unprotected strikes.
