The Australian mining industry spent millions trying to fix workplace culture.
In some areas, it got worse.
THE NUMBERS NO ONE EXPECTED
After the 2022 parliamentary inquiry exposed “abhorrent and systemic” harassment in fly-in-fly-out mining, the industry responded. New policies. Training programs. Reporting systems. Zero tolerance statements.
Then came the 2024 progress data.
Bullying reports rose from 31% to 39%. Retaliation against women increased following inclusivity efforts. Up to 41% of women still reported sexist hostility. And in December 2024, class actions were filed against both BHP and Rio Tinto alleging systemic harassment spanning two decades.
The overt behaviour reduced. The covert behaviour adapted.
WHY COMPLIANCE TRAINING FAILS THE BRAIN
The brain does not unlearn threat responses through a policy document.
When behaviours have been normalised for years, a compliance program does not rewire those neural pathways. It teaches the brain what is now punished. So the behaviour goes underground. The language changes. The intent does not.
This is why researchers found the mining industry could stamp out overt harassment but could not shift the underlying culture. The brain adapted around the new rules without changing the predictions driving the behaviour.
THE PART THAT SHOULD CONCERN EVERY LEADER
Retaliation increased after inclusivity programs were introduced. That is not an anomaly. It is a predictable neurobiological response.
When the brain perceives a threat to established group norms, it pushes back. The threat detection system registers “the rules are changing” and mobilises resistance.
Picture the woman on a remote site who finally reported. She followed the process. She trusted the system. And she watched her career stall while the person she reported was quietly moved to another site.
Her brain learned something in that moment. Not from a training module. From lived experience. It learned: speaking up is not safe here.
Now multiply that across an entire workforce.
WHAT ACTUALLY CHANGES CULTURE
You cannot policy your way out of a culture the brain has encoded as “this is how things work here.”
What changes it is a leader who notices when a team member goes quiet after a meeting and recognises that is not disengagement. It is a nervous system withdrawing because it has predicted this environment is not safe. A leader who intervenes at that moment, not six months later when the complaint is filed.
That is not a compliance skill. It is a neurobiological literacy most leadership programs never teach.
Every industry has its own version of this gap between the policies on paper and what people’s brains actually experience at work. Mining is just the industry where it became impossible to ignore.
What is your industry doing about the culture problems that compliance cannot reach?
