Tbh, if I were his co-workers, I wouldn't like him either. I do like straightforward and confident people, but being purely blunt to the point that you're coming off as arrogant is just too much.
Since his co-workers only see that side of him, it's not unusual for them to dislike him, but I feel like if he opened up even for just a little bit he would make a friend or two.
