Unions NSW has publicly declared it will campaign against the Perrottet government to address growing anger amongst workers across the state.

Secretary of Unions NSW, Mark Morey, told the ALP's state conference in Sydney, union members are now on a campaign footing for the next 160 days in the lead up to the March state election.

Mr Morey said workers were "very outraged" by a drop in wages combined with the rising cost of living and the state Coalition government needed to be "turfed out".

"The NSW union movement will be campaigning in every square foot of this state," Mr Morey said.

"We are going to make the Liberals accountable for the hospital waiting lists, overworked teachers, bungled transport projects, and the jobs for their mates."

"Visit any hospital in the state, any rail yard, any lunch room in any store, warehouse restaurant or school. The workers will tell you the same thing," he said.

"Everything is going up except their wages."

Workers have also been the focus of NSW Labor leader Chris Minns this week, who promised to better protect gig economy employees and boost their workplace entitlements, should he win next year.

NSW treasurer Matt Kean accused Mr Minns of working in the unions' interest. 

"What I would say to the unions and to Chris Minns, is that the public of New South Wales are not their political play thing," he said.

"We should always be focused on what's in the community interest and not what's in vested interests. The New South Wales government will always stand up for the people of this state.

"Chris Minns … works in the unions' interest, whereas we will work in the community's interests."
