Rubbish will be left uncollected by workers in one of Canberra's premier hospitality and nightspots in a fresh round of industrial action over unresolved pay talks.
Government service officers will refuse to pick up rubbish in Braddon on Sunday and Monday a week on from their work ban on rubbish collection in the city centre.
The workers will keep collecting dangerous and hazardous waste, like syringes and broken glass.
The workers, represented by the Construction, Forestry, Maritime Employees Union (CFMEU), want to secure an allowance for front-line workers to recognise the cost of performing essential, in-person work.
The union has said 300 of its members voted in the protected action ballot, an 80 per cent turnout, with 99 per cent of those voting to back protected industrial action.
The union said the industrial action followed nearly a year of bargaining with the ACT government.
"CFMEU made genuine attempts to progress the outstanding issues, but significant matters remain unresolved and some have still not been responded to," the union's ACT assistant secretary Michael Hiscox said.
"GSOs have been left no choice but to recommence protected industrial action. They want to get back to doing their jobs but need a fair pay offer and proper recognition for the essential frontline work they perform."
City and Government Services Minister Tara Cheyne on Monday said the last week's work ban was a reminder of just how important the workers who looked after the city were.
"We've always had a good dialogue with them and we respect their right to take industrial action. We do have an offer," Ms Cheyne said.
"We do have an offer that will be put to a vote and I do believe that we've worked in good faith with our union colleagues across the board to deliver something that meets many of their asks, and certainly the most significant asks in what they also appreciate as a constrained environment."
The union had previously said the government had repeatedly rebuffed the workers' reasonable requests in enterprise bargaining and industrial action could halt "road maintenance, litter collection, sports ground maintenance, park mowing and maintenance of ACT government facilities".
The lowest-paid general service officers secured a 34 per cent pay rise over three years in 2023 and agreed at the time to a deal that was set to push their pay from just under $51,000 a year to more than $68,000.
The ACT government is facing pressure from unions as it works in the latest bargaining round to reach agreements with its staff.
The Community and Public Sector Union has said it would urge public servants in the territory to vote against the latest pay offer.
Government workers were last month presented with an updated deal that included inflation-linked top-up payments in the second and third year of the proposed three-year deal.
The government intends to put that deal for its administrative agreement to a ballot of its staff.
But 66 per cent of CPSU members who voted in a union-run survey wanted to reject the deal, which kept the core pay increases at 3 per cent.
Public Service Minister Rachel Stephen-Smith told a budget estimates on July 21 there had been genuine engagement with unions in an effort to strike new deals.
