OAKLAND, CA - JULY 02: Commuter traffic backs up at the toll plaza to the San Francisco-Oakland Bay Bridge on July 2, 2013 in Oakland, California. For a second day, hundreds of thousands of San Francisco Bay Area commuters are scrambling to find ways to work after two of San Francisco Bay Area Rapid Transit's (BART) largest unions went on strike early yesterday morning following contract negotiations with management falling apart the day before. Train operators, mechanics, station agents and maintenance workers are seeking a five percent wage increase and are fighting management who want to have workers to begin contributing to their pensions, pay more for health insurance and reduce overtime expenses.
