Most Delta employees are non-union.
I have a relative that worked for Northwest for 20 years. She hated every minute of being a part of the IAM union at Northwest as it rewards the slackers and penalizes the hard workers.
Now with Delta, there is no union and she is loving every minute of it. Of course the IAM is absolutely livid that they can't get a toehold into Delta and are pulling out all the stops to see that they do.
Oh. I don't fly anymore either. Drive or nothing :-)
