I work at a regional shop where a person on the team is close family friend with the top guy at the shop (same regional private school in the families, etc.; though this person is much younger than the top guy). It's a tier-2 city / shop. It's been challenging to work with this person as this person will clog up all talking time at meetings, shoot down any ideas that's different from his own, and generally assume the worst of others he doesn't like (he does like a select handful of people but those are also from relatively well-connected families in our local region).
Are there ways to improve one's situation in a case like this? What would you suggest?
