We tend to behave like those around us, at work it's often out of self-preservation. Rise above the gossip and back-stabbing, refuse to take part and understand you need to get away from the people who gossip and backstab. Joining in doubles the negativity. They inevitably turn on you, esp. when you stop participating! Be good not evil.
Walk away and watch out: a person who gossips to you has more than likely already, (or will soon be) tearing you down as well!!! I want nothing to do with the ones who aim to tear others down or the ones ignorant enough to listen.
A busybody is just someone looking to make trouble by exerting false control over the lives of others. Busybodies are tattletales. Scripture says that busybodies are idle people who are neglecting their work and go around looking for negative things in the people around them, often to share with others as gossip or to share with an authority figure to make themselves look better (2 Thess. 3:11-12; 1 Tim. 5:13).
