If you are being placed in a difficult situation at work by a supervisor, colleague, or anyone else who is creating a hostile/difficult work environment, the main piece of advice you will hear is this: "Document Everything."
That's solid advice, but most people don't have much experience with documenting things. If you want a free and easy tool with no strings attached that helps with this, try Chizzle It. Just go to their website, ChizzleIt.com for instructions. It lets you document all kinds of interactions, adds a time and date stamp for every entry, and actually lets you instantly create a custom web page (or pages) that you can share (or keep private).
