Actually, the manager who hired me after Lam let me go was not my boss; he was the Novellus European VP of Sales before he left. He hired me when he heard I was looking.So your boss at Novellus was very loyal - enough to hire you elsewhere. Very good. I had a boss that did the same thing - well he stole me from the first company I worked with him at. Boss is much more important than company.
Novellus may have been loyal. Lam - definitely not loyal.
If some companies used to be loyal, and I suspect even back then they were not, they certainly are not today.
My boss at Novellus, who hired me, was a very tough lady from the streets of Vietnam. She was very hard on me, and others. But she fought for me. And trusted me. And gave me incredible opportunity. "I want you to go out and work with the business. If you get in trouble, come back and tell me. I will help you out."
