The person described in the parent post was so difficult to get on with that they had to be moved to another project, and they are described has having pissed off a large number of people, including more than one level of management. The two possible explanations are, the majority of the company is highly toxic, this particular IC is highly toxic. So unless the posters wife is a remarkably toxic manager, the most likely explanation is that the IC is. Definitely sounds like the company would benefit from sacking them.
