We're going to prevent you from getting to work this morning...in the Bay Area of California;
A labour strike has shut down San Francisco's transit rail system, the fifth-largest in the US, snarling the morning commute for 400,000 people.
Two of the Bay Area Rapid Transit (Bart) system's largest unions went on strike at midnight after last-minute pay talks with management collapsed.
The two sides - each of which said it regretted the inconvenience - accused one another of abandoning talks.
The strike is expected to put an extra 60,000 vehicles on the area's roads.So much for concerns about global warming.
