Doing a 'Bally' 

When someone is doing a 'Bally' they are generally not coming into work because they have a minor sniffle - or in most cases there is nothing wrong them at all, and they had simply heard another person in the work place was unwell, and decided to jump onto their bandwagon.

Person 1 - "Have you seen Woody today?" - Person 2 "He's not in, he's doing a 'Bally'"

Solidarity bullying 

Solidarity bullying occurs when a group of people, usually directed by single highly-amplified individual, falsely labels a person as a troll and the 'community' becomes a pack of flying monkeys who engage in abusive, troll-like behavior on behalf of their master (the supposed victim).

That mommy-blogger sure called out the solidarity bullying today!
