EVERYONE WANTS TO BE A PROFESSIONAL: Once there were just a few professions: medicine, law, the clergy (maybe soldiering too). Everything else was a trade. But as time went on tradesmen wanted to get in on the act and started calling their trades "professions." The latest tradesmen to make the move are nude art models, who have formed a union in Pennsylvania to collectively bargain for better working conditions and so that "we could become regarded more as professionals and not as unskilled people off the street," said model Tomas Dura. I wonder what their professional code of ethics will be?
