Pope Francis and gossip

Below is a paragraph from Pope Francis' Christmas address to the curia.

"Holiness, in the Curia, also means conscientious objection.  Yes, conscientious objection to gossip!  We rightfully insist on the importance of conscientious objection, but perhaps we too need to exercise it as a means of defending ourselves from an unwritten law of our surroundings, which unfortunately is that of gossip.  So let us all be conscientious objectors; and mind you, I am not simply preaching!  For gossip is harmful to people, harmful to our work and our surroundings."

Gossip particularly thrives in organisations that have poor leadership.
