Cheri O'Connell has come out in support of penalty rates after the Federal Government released a Productivity Commission report on Thursday proposing a review of penalty rates.

Mrs O'Connell said the ability to earn the extra money on weekends had helped them through difficult periods.

"My husband is a baker and I'm on a carer's payment," she said.

"Bakers don't earn a lot of money. We couldn't survive on him not earning that Sunday rate.

"If the kids are in school, the weekend is the only time you get to see them. People deserve compensation for working on weekends."

The family made headlines last year when they advocated for the use of cannabis oil to ease the severity of their daughter's condition.

Mrs O'Connell said without weekend rates, there would almost be no incentive to work at all.

"Without the weekends, we might as well go on Centrelink," she said.

"We calculated that we would earn $70 more per week working. It's almost like, why go to the trouble."

Entitled the "Workplace Relations Framework", the report states if penalty rates were de-regulated, it could increase profits, employment and hours worked, therefore increasing earnings.

The conclusion of the penalty rates section states penalty rates are either a necessary element of protecting employees, or they should be purely at the discretion of employers.

The government plans to release the final report in November and take any changes to the next election.

The Victorian Employers' Chamber of Commerce and Industry and the National Farmers Federation are among the groups to come out in support of a review into workplace relations.

VECCI chief executive Mark Stone said the paper addresses areas of widespread concern identified by business.

"The key outcomes of the review must be the creation of a simpler, fairer and more efficient Workplace Relations Framework that spurs economic growth," he said.
