Followup: Who can you trust at work?

Thank you so much for everybody who replied to my post. With all the great input I got from Wenxuecity, I was able to get over my initial anger and concentrate on the future.

It doesn't matter what really happened. One thing I learned is it is critical to form alliances with our peers and management so we will get the support we need when we need it. We can only have certain level of trust at work. in the end all that matters is who you associate with and what is in it for your alliances.
