The only thing you can trust about any company is that it will do what is in it's own best self-interest.

I used to watch people with this "we are all family" frame of mind move into their offices stuffed animals and all; then get their "hearts" broken with a pink slip.

IT is all about the bottom line and when you lose sight of that your just fooling yourself.

Don't bring in pictures and all the junk. Keep a bag packed by the door with your stuff in it and if your office has a white board keep a count down list on it to remind yourself what position you are really in.

That way all you have to do is wipe the board, pick up your bag, put on your coat and leave.
