Perhaps DL is trying to prevent a repeat of the Northeast merger. They've all retired now, but for many of us here, we flew right seat for some of the worst ever "professional" pilots. You'd think after 25 years and 20K or so hours most would have figured it out, but they were about 50/50.

There's always gonna be a few percent you hire that are mistakes, but you have to accept that and move on. When you take on all comers someone else picked, your fear is you just hooked up with another Northeast.
