Every psychosocial claim on your desk started as a hazard someone said they didn’t know about. That excuse no longer holds, and what happens next comes down to what you can prove. In 20 minutes: two recent cases, one employer fined $188,000 for inaction, another cleared this month on proof it acted. The difference was the positive duty at the heart of the new law: find the hazard first. WHS and workers compensation are related, not the same, and by the time a hazard is in a claims file, prevention has failed. You’ll leave knowing what that duty requires.
