The Communications Workers of America says it has photographic evidence showing Verizon Communications Inc. has been depriving its aging copper network of money for maintenance and repair throughout parts of Pennsylvania. The union - which represents 4,980 Verizon linemen, technicians, and customer service representatives in the state - filed the photos on Wednesday in a petition with the Pennsylvania Public Utility Commission, seeking an investigation into whether Verizon has violated state utility laws by not maintaining its copper lines.
