I'm sorry, I'm still not following. Are we certain that the airline your friends are working at (worked at) is Emirates in Dubai. There are no former Evergreen pilots here who were hired in the 1980s. The most senior American was hired in 1996 and came from USAir. The second most senior was hired in 2002 and came from Sri Lankan. Of course, I'm still assuming your friends are American. If they are not then it becomes more plausible.
That said, your friends statement is actually not far off. The Americans who were here near the beginning, ex Eastern late 80s/early 90s, left something of a bad after taste. Not all of them, but it only takes one to ruin it for all of us. When I was hired it was very difficult for an American to get an interview. That has since changed due to a change of policy from the President of the airline, who near the same time banned the hiring of Australians for a year.
Just saw your response as I was typing this, thought I keep it here though as it does have some information that could be valuable to other people lurking on the boards.
