How to protect myself from being talked about at work after whistle-blowing?

Start looking for another job immediately! Once you find on, leave there without notice, or give notice (they will pay you for two weeks and cut you loose!) It will then fall on the 'boss' to make sure the project does not go under, and from what you describe, it sounds as if he will not be able to deliver. Rent the movie, "MR. MOM, for a recap of what I am saying...what goes round always comes round! But find the new job first! Be a "yes man" until that day you walk! GW
