The ABC has apologised after admitting it has been underpaying some "flat-rate" casual staff over the past six years.
- A detailed review is underway to confirm how penalties, allowances and loadings should have been calculated
- The ABC is notifying all affected employees
- The CPSU and MEAA unions are both involved
Head of public affairs Emma McDonald said in a statement that a detailed review was underway to confirm how penalties, allowances and loadings should have been calculated and applied in the cases of some 2,500 staff.
She said the broadcaster was notifying affected employees and reviewing its processes.
It is not clear how many of the 2,500 staff have been underpaid.
"The Fair Work Ombudsman has been notified and the ABC is liaising with them in relation to this situation," she said.
"The Corporation is having discussions with the CPSU, which brought the matter to the attention of management, and intends to work with affected staff, the CPSU and the MEAA to address their concerns.
"This error should not have occurred, and the ABC apologises to any casual employee who has been underpaid.
"The ABC is actively working to remedy this for affected employees as soon as possible."
Last year the Federal Government announced it would freeze the ABC's annual funding indexation for three years from July 2019, costing the organisation $84 million.
