The Media, Entertainment & Arts Alliance has condemned the latest cuts to secure jobs and diverse voices at the ABC.
MEAA Chief Executive Erin Madeley said mismanagement and cuts to staff and public interest reporting and programming was undermining the ABC's mandate.
"The ABC is one of Australia's most important institutions. It needs to be well funded and accessible to all Australians," said Ms Madeley.
"Management is driving instability through a flawed commercial model which simply doesn't fit with the public interest test.
"Staff are being told they may lose their jobs because they don't live and work in Sydney, where the majority of ABC's staff are already based.
"Decreasing the voice of Australians who live outside of Sydney, and moving staff around like chess pieces is doing a disservice to the public.
Ms Madeley said MEAA would continue to campaign for a fully funded ABC, but also for the quality jobs that quality journalism demands.
"The ABC needs fully restored funding and to provide secure, sustainable careers to the workers who tell our stories.
"Mismanagement of the ABC and its budget has led to cuts to jobs, public interest reporting and programming with workers wearing the risk and pain.
"QandA is the latest victim of these cuts, despite playing a critical and unique role in our democracy, where the public can speak to politicians on a national stage.
"We are seeing an ongoing drive towards insecure jobs at the ABC, which also impacts staff retention and the ABC's ability to function the way the public needs."
ABC staff are encouraged to get more involved in MEAA's campaign for a sustainable future and MEAA is providing support to staff affected by today's fresh round of cuts.
