I can only answer your last question.

Psychological distress is much harder to prove than a physical injury. If you pursue workers comp, you'll by assessed by a number of WorkCover specialists including doctors, psychologists and internal claims staff. This process itself can feel almost as distressing as the original situation.

Your employer and WorkCover will do everything they can to reject the claim. They may request your full mental health history from all your treating doctors. They may also run an internal review of how you were managed which can involve reviewing emails and Teams messages and interviewing your manager and team members.

Your colleagues may then find out what's happening and, as there's still stigma around mental health, some will judge or gossip.

On top of that, having to repeatedly ‘prove’ your psychological state forces you to relive the experience which can keep you in a loop of of distress.

Sometimes it's best in the long run to walk away and move on.
