cfmeu fined $1.25m, page-8

"It is not worth it to compromise safety...besides, Workplace Health & Safety Reps regularly visit work places to ensure worker safety is not compromised, if a worker feels threatened or compromised a telephone call fixes that. Then even if the company found out who it was and were to consider sacking that person for "dobbing" there are strict laws that prevent that too to protect workers."

Workcover doesn't do many snap visits.Its not like the adds on telly.
Plenty of notice is given.
Unless there is a major incident.
The laws to protect workers are easily circumvented with the old "sorry we haven't got any work"
Company safety officers Pftt,i have been working on site where the water covered the whole floor and was coming down on the temporary boards and the SO still refused to send people off site.
Only when threatened with calling work cover did he change his mind.
