This is the part where I tell you to fuck off to the desert.
I deal with this sort of human factors shit in my day job (though not in a safety context). Just with money and computer systems instead of Pablo losing a hand.
By adopting BS policies that take agency and discretion away from the workers management (either on or off site) is taking on responsibility for making sure those policies are fit for their purpose, complied with and what happens when everyone does shit right and shit fucks off anyway.
On the other hand, it does really give supervisors a lot of discretion to frame people or shift the focus away from "I suck and what we're doing is fundamentally risky" to "we'll just train people better" when shit does happen.
At the end of the day the owners and top managers are ultimately responsible or liable for almost everything to an extent so it's kind of a wash. You either waste money investing in preventing mishaps or you invest money in paying for the results of the mishaps. I think at the end of the day it's mostly a wash as long as the policies aren't stupid as fuck.
INB4 a real desert dweller shows up to willfully misunderstand me.
