Slightly related and maybe of interest on this topic. My last career in California, I was a union worker. In California, you can't usually sue your primary employer for a huge list of workplace injuries. I had about a hundred employers a year, all under a common agreement.
They got together and created a set of qualification courses under the name "Safety Passport training". Ostensibly this was to enhance the worker's safety by having more informed working staff. But everybody was 100% convinced it was for the purpose of shifting liability. Same theory, they were mentally creating a situation where a worker would be less likely to bring successful suit because they officially should have known what constituted safe working conditions, so if they were injured, it had to have been their fault.:doh:
