I totally agree. Getting laid off once will shift your world view. The company is generally going to act in its best interest, and so should you. I love my current company and feel 'loyal' in a general sense, but that's because they treat me exceptionally well and constantly throw cool projects at me.

Here's what I don't get. All of my contracts so far have been for 'at will' employment -- meaning either party can terminate employment at any time. If you want to keep someone around a while, why not have them sign a 3 year contract? I would consider signing such a contract if the incentives were right.
