Didn't think employees could report stuff to the icc? Not much point in HR but guess have to try that route. I'd go straight to a decent lawyer and there are a couple that have won against casa. There was one newbie manager to casa that got a bullying case against him within 6 months. Apparently the complainent (iOS) used a good lawyer based in Melbourne. The manager put some nasty stuff in writing amongst other things. Still there the complainent isn't though. Although a number of jobs are being restructured now.
Funny how bullying and harassment keeps cropping up. Casa has a duty to provide a safe workplace and that includes emotionally safe too.
Always worth a read
