Some Melbourne firefighters will be entitled to more than 130 days leave in a year under a workplace deal the Victorian Government has been warned will entrench inequality in the Metropolitan Fire Brigade.

Premier Daniel Andrews is facing fresh pressure as Parliament resumes over an enterprise bargaining agreement with the United Firefighters Union (UFU) containing clauses allowing for a combined total of 133 days leave for some staff who have served for three years and have not taken any personal or sick leave. These are staff that work on average 42 hours a week.

The 322-page deal also contains a suite of allowances, including for having a second language and for operating a drone.

It also includes the continuation of union consultation on operational matters which critics, including former management, have labelled a veto.

The Government says it is appropriate for staff in a dangerous work environment to be consulted.

Details of the workplace deal emerged as the Andrews Government tried to hose down concerns aired by the state's Human Rights and Equal Opportunity Commission that it would not be compliant with industrial laws.

Fairfax has also reported the consultation clauses would make it difficult to improve diversity.

The commission has prepared a report into sexism, bullying and harassment within the CFA and MFB, which the union is seeking to supress in the Supreme Court.

Leaked notes contained warnings from the commission about the workplace deal, following similar testimony from the MFB corporate secretary in the Federal Court last month that said concerns were ignored.

"Rather than responding to notes taken allegedly at some meeting, we'll wait for the final report to be tabled and then we will act on it," Premier Daniel Andrews told ABC Radio Melbourne.

"In terms of cultural issues within the CFA and MFB, we've been very clear about the need for cultural change to be made, that's why we've sent, as a Government, we've sent a reference off to the Human Rights and Equal Opportunity Commission."

Peter Marshall from the United Firefighters Union called it "clever accounting" saying the entitlements were no different to any other workplace.

"Well it's certainly not that much leave," he said.

"So you take bereavement leave, which not everyone does, and if you take carers leave, and if you take adoption leave and then you put annual leave.

"If you put all those things together it's no different to anyone else in any industry.

"It's clever accounting designed to demonise firefighters."

'Regretful' equal opportunity report notes leaked

Victorian Equal Opportunity and Human Rights commissioner Kristen Hilton said confidential draft extracts were shared with the MFB, the CFA and "other key stakeholders" prior to the report's publication.

"This allows the agencies to provide feedback, suggestions and corrections, which the commission must and will consider before it publishes its report," she said in a statement.

"We regret that notes from a confidential briefing to the MFB appear to have been leaked to the press before the report is complete. The notes do not necessarily represent the commission's final report."

Firefighting a 'dangerous occupation'

In relation to the workplace deal, which includes a 19 per cent pay rise over the life of the agreement and expires in July 2019, Government ministers said firefighters deserved respect.

Emergency Services Minister James Merlino said he was confident the workplace agreement would comply with equal opportunity industrial laws.

He also said there was a formal commitment from the union and management to tackle inequality.

Mr Merlino said firefighters had been "vilified by the Opposition".

"Our firefighters deserve the security and respect of a workplace agreement, these are brave men and women who put their lives on the line to save property and lives," Mr Merlino said.

"If you are in a burning home and you have got a firefighter bashing through the door to save you and your children, do you think you care what they are paid? What allowances they receive? This is a dangerous occupation."

Opposition Leader Matthew Guy said the Government had questions to answer.

"This is a stinking rorting mess that the Premier and the Emergency Services Minister have created and presided over, and continue to condone," Mr Guy said.

He also said the Premier had to clear up why the advice of the Equal Opportunity and Human Rights Commission was ignored.

The long-running industrial dispute in both the CFA and MFB has been a political problem for the Andrews Government for some time.

Former minister Jane Garrett quit her post in 2016 rather than forcing the CFA board to agree to a union deal which was backed by the Premier.

And the Labor Government faced a backlash from CFA volunteers and their supporters over flagged reforms of the state's fire services.

There are members of the Government who said they were still baffled at the backing the UFU has received from the Premier.

"Well it's certainly not right. It's clever accounting. We've already done an analysis. It's no different to any other workplace if you calculate all the other different leave entitlements. So that's a beat-up," he said.

Editor's note (29/3/18): The ABC originally counted 196 days leave every year. The suggestion of every year was wrong.

After discussion with the United Firefighters Union in March the ABC understands that a firefighter with three years' employment could have up to 133 days of paid leave in a year.

This is based on 65 days of annual leave, a personal and sick leave entitlement of 54 days assuming none had been taken in the first three years of employment, 10 days community service and 4 days of pressing necessity leave.

Staff are also entitled to five days' union leave a year but this has not been counted in the 133 day figure.

Leave is subject to approval.

In the ABC's original calculation of 196 days, sick and personal leave were counted separately because the workplace agreement says "in addition to personal leave" when discussing sick leave.

The union says this is incorrect as both entitlements are drawn from the same pool.

Public holidays were miscalculated based on confusion in the workplace agreement between on and off shift staff.
