The Morrison government has launched a review of workplace laws.

Treasurer Josh Frydenberg says the process will look at ways to strengthen the Australian economy, primarily by encouraging businesses to create more jobs.

Labor leader Anthony Albanese believes wage increases should be the first priority.

The business sector wants changes to unfair dismissal rules, and has backed a government bill making it easier to de-register unions and disqualify officials.

Industrial Relations Minister Christian Porter says the six-to-nine-month review will include the definition of casual employment.

Stagnant wage growth is putting pressure on household bills and affects the national economy.

“That should be the government's focus,” Mr Albanese said.

Mr Frydenberg said job creation would take precedence.

“Our focus, as a government, is what steps can we take to continue to strengthen the Australian economy and in doing so, what steps can we take to encourage businesses ... to employ more people and to continue to see more jobs being created,” he told reporters in Melbourne.

Mr Albanese said the government has not understood that organising workers is an essential component of democracy.

“They're actively undermining the freedom of organised labour and that's an important principle in a democracy,” he said.

The ACTU called on the Coalition to focus on better addressing insecure work.
