Call OSHA when they inevitably fuck things up. Then, make it known that you're the one who called OSHA. They'll retaliate, which is illegal, then sue if they have any money left. OSHA standards are esy to research, and goo knowledge to have. An easy one, is that under most circumstances, nothing greater than 40 lbs should be stored above your head. I have it on good authority that warehouse guys fuck this up, all the time.
I stole this idea from a nigger (haha, how the tables have turned) who claimed to have done this successfully.
If you have ethical concerns about using Feds to fuck people over (especially OSHA), that's understandable, but the entire premise is ethically dubious to begin with. You're much better off just focusing on finding a new career where you can thrive. This company will probably destroy itself.
Good luck, I'm sorry you work for a bunch of retarded assholes.
