WorkSafe ACT says it has found a complaint about bullying made by an ACT Ambulance Service paramedic was ignored, despite its seriousness.

The safety watchdog says the bullying complaint levelled accusations against senior staff, but the Justice and Community Safety Directorate, through the Ambulance Service, failed in its duties under by not conducting an investigation.

WorkSafe does say that some steps were taken to manage bullying allegations, but a formal improvement notice has been issued for the directorate to conduct a full and independent investigation.

The bureaucratic misstep has been pounced on by the ACT Opposition.

“This was brought to minister Simon Corbell's attention some years ago,” Opposition spokesperson Brendan Smyth has told the ABC.

“He promised a review into the toxic culture last October. We're yet to see that review commence.

“As a consequence of his inaction we now see that WorkSafe ACT has issued the Government with an improvement notice saying you're not complying with the law.”
