I'm quite often rude to others at work and I freely admit it. Reason: ofc I feel I am justified to be so. Just like everybody else I feel I am right. I am not rude to everybody. Just people who don't want to carry their weight but want an equal share of the pie. I am rude to Project "Managers" who only assign story points in jira. To product owners who always side with the external client and dump the technical team…
If multiple people have made HR complaints "behind your back", you are not competently performing your job. (This directly affects your claimed 3X performance because you drag down your coworkers.)
