The SF Ferry workers went on strike on May Day in "solidarity" with Occupy SF presuming that they would help the Occupiers create the maximum chaos by forcing all the Ferry customers onto the Golden Gate Bridge but the Occupiers decided not to cut off traffic on the bridge, that made the Ferry worker's walk out not nearly as relevant.
It might actually hasten the demise of the Ferry since it's a money pit and only kept afloat by the bridge tolls.
