I imagine it works exactly like those e-learning crap companies force you to do in your free-time. You get a pop-quiz like 'do you ever take risks at work' and the answers are
A) No, never, absolutely never!
B) Yes, but only after proper assesment, consulting superiors, taking all the precautions, doing all the checklists etc. etc.
C) Yes, all the time! I'm basically a retard! Fire my ass.
You think it's B, because there's literally no way to 99% of your job in this line of work without taking risks - fucking weather will change to windy and you're already under much more risk. So you pick B, and no, fuck you it's A. Because it's either black or white. You show a sign of not being completely okay, they'll pin all kinds of X Personality Disorders, all kinds of happy pills, all kinds of examinations you must take. The machine is hard at work discovering new 'mental illnesses' so everybody can relate to something. All that at 50$/hour rate.
