The Electrical Trades Union has pulled out of talks with the Queensland government over plans to create a state-owned renewable energy generation company.
The union says treasury officials have pushed ahead with an October 1 deadline to set up the corporation, CleanCo, despite concerns about how workers fit into the transition from coal and the requirements for working on clean energy projects.
"They expect a rubber stamp and we will not be part of a sham process that hangs Queensland workers out to dry," ETU state assistant secretary Keith McKenzie said.
"The government talks a lot of hot air about just transition for workers, we have seen nothing and in fact it is negligence by inaction."
But Premier Annastacia Palaszczuk is confident talks with the union will resume.
"Of course I'm disappointed that they're not happy at the moment in terms of discussions, but I'm quite sure we can talk to them and get them back around the table," she told reporters on Thursday.
"These are early days, early discussions, we remain firmly committed to setting up CleanCo."
The government says the state owned corporation will help it meets its target of 50 per cent renewable energy sources by 2030, and put downward pressure on power prices.
