San Francisco Transit Workers Strike
San Francisco, California (CNN) - The bay area rapid transit unions went on strike early this morning bringing public transit in San Francisco to a screeching halt.
The strike started at midnight local time after union leaders walked out of last-minute negotiations with BART.
It came just hours before their four-year contract was set to expire.
The dispute centers on pay and benefits.
The strike is expected to hit commuters hard.
A BART spokesman says about 400,000 people in the San Francisco bay area use the service every day.
Bart says it plans to offer limited bus service during peak commute periods to ease the effects of the strike.
