Same here. Sometimes “hostile and toxic work environment” is just that, a toxic and hostile work environment. “I am not at ease around this person” does not have only one possible answer to fill in the blank.
And the whole “he’s a neurotic asshole but oh the results he delivers” thing is overrated. Especially because it’s more often used to give license to other people who are just plain assholes, to claim that to be their case – or that if the way you are treated stays just this side of criminal conduct, then it’s not abuse and you should not complain.
