THINGS ARE heating up in the labor wars at the Goldtex Apartment building in Callowhill, as two union protesters have been arrested for allegedly assaulting a subcontractor working at the mostly nonunion construction site. Surveillance video shows a scuffle at the work site that ends when two of the protesters use a section of chain-link fence to smash a worker against a stone support that holds up the Reading Viaduct. The worker collapses and lies on the ground for a couple of minutes. "At least four police officers showed up at this [one] man's house Saturday afternoon and handcuffed him and escorted him out in front of his family and neighbors," said Pat Gillespie, business manager for the Philadelphia Building and Construction Trades Council. The other man turned himself in Monday. "From what I understand, it was a shoving match; there was no damage of any kind," the union leader said. But Michael Pestronk, one of the brothers who own Post Brothers Apartments, said the contractor was knocked unconscious and an ambulance was called. He said he and his brother Matthew showed video of the alleged July 12 assault to Michael R. Resnick, the city's director of public safety. "The union has every right to be out there," Resnick said Monday. "They have constitutional, First Amendment rights to protest, to hold up signs. But what they don't have the right to do is to commit crimes, assault people and destroy property." http://www.philly.com/philly/news/2...g_match__at_Goldtex_site.html?cmpid=124488459
