Drivers employed by San Pedro-based Toll Group held a march Thursday, claiming they are underpaid, forced to use unsanitary restrooms and were intimidated by a "union-buster" hired by the trucking company. During the rally, workers were blocked from presenting their managers with a petition signed by more than 1,000 Harbor Area residents, urging Toll Group to provide better working conditions for the company's 75 drivers who are regularly dispatched to the ports of Los Angeles and Long Beach. So far, 62 drivers have signed a petition stating that they want to unionize, said Xiomara Perez of Lakewood, who has worked nearly three years for Toll Group. "We are organizing for better work conditions because our restrooms are so dirty, there's no place to take a lunch or rest and we want to stop the intimidation," Perez said. "They tell us that if we don't like the company, then we should leave ... but I know my rights and I should be respected." Managers at Toll Group's office in San Pedro referred calls to the company's U.S. headquarters in Carteret, N.J. Executives at the company's New Jersey office declined to comment. - Art Marroquin
