That said our boss was quite a progressive guy and reached out to hire a black guy and several typical American women. The women were a disappointment. It has to be said that they proved to be demanding low performers. Had high expectations of everything and everyone else, but didn't really put points on the board for the team. In talks about the women I learned the US English codeword PITA, not the flat bread, but Pain In The A**. It was true.
The black guy turned out well. In the first couple months he was very reserved and looking back I think he was very keen to not make mistakes or rub anyone the wrong way. But man, after that first 90 days or so, he relaxed and realized we weren't going to bite him, and he started learning the craft with real zeal. He was one of the hardest working fellows I ever met in my time in the U.S.
I think the dynamic is that black people in the U.S. are all too accustomed to having "the prize" and opportunity dangled in front of them, and then snatched away once someone has got what they wanted from that black person. So they I think have learned to regard the larger American system with suspicion or at least much caution. However if they see by actions and not words that something is the real deal, the team is there and they are part of it, no bait and switch, they really get fired up and loving it.
