Eroding Trust in a Single Word

I attended a meeting once where I disagreed with how my coworker was conducting it.  Instead of gently redirecting the discussion or privately bringing up my concerns afterwards, I called the person a name right in front of everyone.  It was an impulse to release some tension and perhaps shock my coworker into changing direction.  I meant no real offense, but it was completely off-base for workplace communication and I derailed the whole meeting.  The remaining conversation was awkward, tense, and unproductive.

Note to self: You can undo months' worth of work in seconds when you're not careful with how you interact with others.
