Good for them. When these gigantic corporations and CEO's chose to merge with other airlines, they have to know that trying to merge two different work groups together will be like to giant trains colliding at each other in very high speeds. In fact, I believe they feed off the complications and discontent in order to destroy the unions. This while making huge gains for themselves. They tend to forget whom gets them those gains. The very foundation itself. It's employees. (This is not to say that some unions ask way too much at times.)
