To get a good perspective on that.... I've never worked in the rail sector, and I'm only starting to hear more and more stories. When I started, I asked if I could go on site and ride the train with one of the Teamster members, and I was told no, because the risk to my personal safety was too high.
It is a workplace, where people have died. Every year we hear horrible stories, so I think it's definitely a sector in which, if your personal safety is constantly at risk, there is an inordinate amount of pressure. I don't doubt that many would end up leaving because of that.
