I'll start and then I'll pass it to Mr. Beatty.
Our poster boy during the rail safety amendments was Brother McDavid, who was fired for not having his bootlaces correctly tied as he was leaving a cab to sign off. What you're talking about may, in 10 or 15 years, similar to pilots who have processes in place—non-punitive processes—upon agreement with agreements.... We're dealing with companies who fire people for not having their bootlaces correctly tied. So when you're talking about the future, let's start baby steps, and what you're talking about is way down in the future, just like with SMS and everything else. But at this point, these companies—you've heard the stories and the grievances—they're simply not trusted by the membership. Mr. Beatty will have more practical responses.
