A strike by commuter rail system workers in the San Francisco area entered a fourth day on Monday, as the traffic-clogged region started the work week with no labour talks scheduled. Bay Area Rapid Transit employees walked off the job on Friday after contract talks broke down over pay increases and workplace rules. The strike shut down a commuter rail system that carries some 400,000 passengers a day.

The BART Board of Directors is set to meet in Oakland on Monday afternoon to discuss the talks with the transit system's general manager and its labor negotiations team.
