Can I be blunt: Don't gossip.
Talking about others when they are not around is lame. The old axiom holds true: if you don't have something nice to say about some don't say anything at all.
James calls the tongue a wild fire that can destroy what it touches. Watch your tongue. Especially as a leader. Don't talk poorly of others, or others will think you talk poorly of them when they are not around.
Gossiping is easy and feels good because it appeals to our sin nature. Remember that nature is being renewed and restored into the glory of God through Christ.
Don't let any salt water come out our your fresh spring of life. They don't mix.
