We're always evergreen, always willing to improve, but I believe that the mandatory training is something that is quite robust right now with regard to, “You don't have a choice; you have to go. Here is the orientation, and this is what you need to know.” No employee goes without that right now, so that's actually quite a robust approach to take.
It's also quite robust to be able to put one of these little booklets in their hands and say, “This is your code. You need to abide by this, so when you sign this letter you agree that you're going to abide by this.” That's pretty robust too, so I'm feeling pretty confident.
