No matter how people perform on any side, It sounds a little draining to work with people you don't like, regardless of the reason of dislike. Some people aren't in control of that so they just suck it up, whereas others get a say over their lives. The question is whether they will find sufficient incentive to prioritize company interests where they differ. One thinks of that when one joins a team with a lead that is a center of social activity outside work, and whether one has the energy to participate. When social dynamics are involved things are always a bit more complicated than the performance which strictly happens at work.

If people don't want this, I think it's up to the organization to do this, as opposed to the vigilant wall of an ethic. Presumably the organization doesn't want little cliques, and should structure their incentives properly.
