If someone in my organisation went around making it known they "wanted blood" they would be pulled aside and put on a training programme to learn to respect others. If it came about as a second offence shortly after they'd been called out for intimidating others to the point they were reduced to tears, then the bully would be ejected without notice. It's toxic behavior that just would not be tolerated in our (high pressure, high performing) environment. We deserve a lot better than this. These people are supposed to be public servants. Addressing other public and civil servants in a way that evokes this kind of language in a format that ends up on public record is absolutely appalling and should not be tolerated.
