Yeah I am in Oz, reading about dingo packs attacking their prey, they take it in turns, just like wolves or the wild dogs of the Sahara.

In Nursing, I noticed that if one of the female nurses is pissed off with someone she will find out who are her allies and then they gang up on the person using very covert tactics to make their life miserable.

It can involve the cold shoulder, being hypercritical of something, being too busy to provide assistance, etc.
