Sounds great, until whoever does get injured or even killed tries to sue anyone and everyone possible because they did nothing to prevent the accident. That is why there is seemingly ridiculous safety policies. If you were working at a Walmart, the greed kicks in in the courtroom, lets go after the employer, the GC, other trades that may have any connection to this, and of course Walmart as well. Even though the individual may have done something stupid entirely on his own that was the primary cause of whatever happened.
