I agree that choosing your team isn’t always an option and it’s better to find people who are good at what they do. For this reason, I don’t think it’s necessary to have someone you already have a good relationship with. In an actual job, everyone is there to fulfill their duties and get the job done. If they choose to be difficult, they are doing so at the risk of getting fired or reassigned somewhere else. It is my belief that most people are mature enough to put aside any differences they may have with others in order to keep their job secure and put forth the best product/deliverable possible
