At work, I deal with probably 50 or 100 people on a regular basis in various teams and interactions and the department and such. Most of these folks are perfectly pleasant to work with. Sure, everyone has their quirks, but overall our interactions are good. About 4-5 people, however, are different. If you are having a meeting with 14 people and one of these people is there, the character of the whole meeting changes. Suddenly everyone is on eggshells, or the meeting is getting interrupted every three minutes by this person with some inane comment, or whatever. I call these people "the moles" because, I'm sure without realizing it, they sabotage any environment they come into. Everyone can be laughing and having a great time at lunch until The Mole shows up, and all fun dies. A really amazing design meeting can be happening until The Mole arrives, and that's the end of creativity. These people may be hard, productive workers, but they are the collaborative and social equivalent of VX nerve agent. Alternatively, they may be fine in social situations, but as soon as they start "contributing" to your project, everything goes off the rails. Probably the whole organization would run better without The Mole, but since they never do anything too egregious it's impossible to fire them, so you're stuck with them indefinitely. FOCUS: Do you have a Mole or Moles in your life? How do they poison every situation they become involved in? What redeeming qualities do they have that prevent them from becoming totally ostracized?
