It’s easy to sucked into petty disputes and inter-office politics, but as the leader you need to rise above it. You must always remember that your employees take their cultural cues from you. You are a role model! If you get enmeshed in office gossip then they will. If you use a divide and conquer management approach than they will do the same. If you treat people poorly and/or without proper etiquette then bad behavior towards others will become acceptable. If you have a short fuse, then anger will become an acceptable management strategy.
