Workers at Australia's five main airports plan to protest pay and conditions as part of a global day of action.
The Transport Workers' Union says the protests on Tuesday will coincide with it releasing its submission to the Productivity Commission's inquiry into economic regulation of airports.
The union says the submission warns that low standards are affecting aviation safety and security.
"Airport workers have seen their jobs downgraded in recent years with a majority on forced part-time hours," the TWU said.
"The low rates, split shifts and poor conditions have led to workers forced to sleep at airports."
