Well, xrongor, I agree with you. Wholeheartedly.
I was on the fringe of those people and the replacements needed to interview me and others in my department, too. I am one of 5 ADABAS and Oracle DBAs.
I sort of, kind of did what you said except I did help at the barest minimum. I told the guy who was heading up the outsourcing project that I did not want to answer their questions. I told him I despise that company, I despise their mission statement (which can be summed up in a few words: "Rape the American, steal his job, and let him gnash his teeth on the street while he tries to find work."), and I certainly despise the people I would talk to becausethey are the ones who are doing it.
And I told him I would say it to the guy(s) who were coming. He said I need to do what I need to do.
When the guys came to me, they stuck their hands out to shake mine and I looked at them and shook my head "No." They were extremely surprised. Then I proceeded to tellthem I hated their comapny, its mission statement, and I truly had a severe dislike for them. I answered their questions truthfully but curtly. They sat with me for about 15 minutes--everybody else did what you said NOT to do and these guys were with them for at least 4 hours a piece. And they kept coming back to everybody...except me.
This all happened around July of last year. Now, everytime they see me in the ha;;, they almost run away. If they NEED to come and see me, it's like they crawl over. It sort of feels good but I am still so darn pissed the 30+ are gone--and several were very good friends of mine, including one of the guys that moved his family.
All I can say is I said what I said and I did what I did and I am still here, so there may be something in what you say!
