I'd say: What's managements position? are they happy with it? unhappy with it? Without support from above? you're screaming at the air. If they have support? Then I would say a restructure should happen. People get switched around in teams to start to "balance out" the "diversity" so it's not all one ethnicity in a pot. Second... hiring should happen with multiple inputs. That manager is biased? Are all the managers biased? No? Then he doesn't make the decision alone anymore. If it's a 3 manager panel that decides? 5? and there has to be consensus or majority rules votes? Third... teams in my company come with a maximum size. If the team has no more room then new hires go elsewhere. If his team is too big? Time to break it up or move some program from his group to other groups. Something to "rebalance" the equation. But really, these are decisions that are generally make or break by corporate culture and without buy-in from above? Then there's nothing you can do.
