I worked in a rubber factory. We made what’s called “mother mixes”: “uncooked” premixes which other companies turn into tires and so forth. The first step of our process was cutting up chunks of rubber into more-manageable pieces, then placing fixed amounts of the chopped-up pieces plus whatever coloring, coalblack etc was required in a mixer.
The guillotine had a double dead-man’d switch. If used as designed, it required two separate people puching on two buttons at the same time; the buttons were far enough that a single person would not have been able to punch both (not even Pau Gassol). So, what had the workers done?
Tamper with the wiring, of course. The ones who used their foot to shuffle the rubber around the guillotine’s base were seen as more careful than the ones who used a hand while flailing about with the other until they hit the button :smack:
Between practices like that and having been the house of the Most Hateful Boss I Ever Had, I promised myself that if I ever hit the lottery, I’m buying me that factory and fixing it. I’d go into the door the first day with a couple electricians in tow and send them to fix all the dead’s man switches, then fire the Bitch From Hell.
