CC firing squad

People who in a figure of speech execute colleagues by sending an attacking email containing critique or feedback, whilst cc-ing as many (senior) colleagues as possible. By doing so, they lower a person's self-esteem, position in the team and try to be perceived as knowledgable/responsible.

"She sent me this email telling me she's afraid I'm not going to make a deadline and pointing out I forgot two small tasks. She even cc'd my team and team manager. She's definitely part of the cc firing squad."
