Governance and interests

Workplace review and representative claim

2021–October 2026 · documented · high materiality

An independent 2024 survey review found 39% of respondents reported bullying in the prior 12 months, compared with 31% in 2021. Rio Tinto reported a representative workplace claim commenced in December 2024. On 23 October 2026 the Federal Court struck out specified claims and pleading paragraphs, allowed some repleading, and otherwise dismissed Rio Tinto’s interlocutory application; this was a procedural ruling, not a finding on the merits.

Attribution: Role overlaps event; causation unproven. Trott became group CEO on 25 August 2025, after the 2024 survey and case filing. His current group role overlaps the ongoing proceeding; the sources do not allege personal misconduct by him.

Relevance: Relevant to workplace culture and governance.
