If you have been a leader for over a month :) you will know the feeling. The feeling of being back-stabbed.... the feeling that someone is talking about you...gossiping about you or the way you handle things... Sad to say but this is part of the gig.
I found a short article to help with such times. I love the last 2 lines: "The greatest leaders I know are not easily offended. Instead, they practice the habit of overlooking offenses. They take the high road, give the offender the benefit of the doubt, and move on."
