Like carbon dioxide, this ever-present danger will poison and kill you before you can even detect a problem. Here are five warning signs to help sniff out a crooked co-worker:

1. Your co-worker collects posters of the Russian oligarchs.

2. Your co-worker finds a way to work embezzlement into every sentence.  “Are you going to finish those pretzels or can I embezzle some?”, “How were drinks last night with Nancy? Did you take her home and embezzle her?” or “Oh what am I working on right now? This and that … you know, not embezzlement (NERVOUS LAUGHTER).”

3. Your co-worker has Chicago roots and a Polish name that sounds like the phonetic spelling of a sneeze.

4. Your co-worker lapses into fits of paranoia, often accusing you of being “more wired than O’Hare International Airport on a moonless night.”

5. Your co-worker keeps trying to sell you.
