You either didn't watch the video, or you missed the part where they talk about f/o's having other jobs on their days off to make ends meet, which, if you've ever worked another job while doing this, you'd know that it will start taking a toll on your mind and your body. Thus affecting situational awareness, crm, cognitive thinking, you see the connection now? Or should I illustrate it a bit more. I was one of the lucky ones, I had savings to compensate during my first six months, I only had to get a job for the second six months of my first year, I can tell you from personal experience it was extremely tough on my mind and my body. I was one of the fortunate ones, I work for a company that has pretty good work rules. Now couple my previous mentioned situation with a company that has questionable work rules, and you got yourself a potential hazardous situation every time you go up.
