AA searched their exchange database for the text I posted, found the guy, and fired Mr. X on the spot.
As upsetting as this is, it's just not that big of a surprise. Some companies take non-disclosure very seriously. Why didn't Mr. X just use gmail? I can't imagine discussing any company's internals on their own email system.
OTOH, maybe Mr. X just committed corporate suicide by email. That's one way to escape the insanity.
Thanks for the update, Dustin. I sure hope Mr. X lands on his feet fairly soon and I applaud your contribution. I like to think that integrity still trumps idiocy.
