There is a common behavior that destroys culture, trust, and performance. It happens more often than you think. Have you participated in this behavior? Have you been the recipient of such behavior? What is it?

"If you don't have something good or productive to say, don't say anything at all." That's not to say that candor and openness should be eliminated, or important information withheld that could help the team succeed. It means eliminating "gossip" and "slamming" employees or teammates BEHIND their backs. Take complaints or constructive feedback to that person directly. Be real. Be an ambassador of goodness and character! Be a builder.
