<p>NEW YORK — Labor groups usually fight for retirement and dental plans, but a group of Philadelphia workers want somewhere to hang their clothes while they work — in the nude.</p>

However, unlike blue-collar workers who block gates, picket and chant for rights, the guild is trying to open up communication lines between models and the schools where they pose for art students.</p>
