My brother recently had an issue with a co-worker who would send an email at 4 am, then follow up at 6 am with a phone call asking why my brother was being so lazy and using very abusive language. On weekends. Issue was referred to Fair Work and after much drama was resolved by the sacking of the co-worker for being unprofessional (well that's what it amounted to). Keep records of this shit if you feel inclined. Took my brother about 7 months to amass enough evidence of the co-worker's abusive work habits to convince Fair work. The co-worker was doing it to others too. Not the public service - a non-govt service provider. Co-worker had to pay triple time per hour for the weekend calls/work as a fine to each person he was doing this to, and double time for calls during the week but out of normal business hours as specified in the work contracts. Added up to a nice large sum over the 7 months. I understand the abuser had to sell his house to pay all the fines.
