If BART and its unions can't come to an agreement over the next two days, Brown said he will ask the San Francisco Superior Court to enforce a 60-day cooling-off period. BART workers would not be able to strike within those 60 days.
"I urge all parties to think of the public and resolve this matter without delay, but if there's no resolution by Sunday, I will seek a 60 day cooling-off period," Brown said in a statement.
Brown first stepped in last Sunday, when he appointed a three-person board of investigation to study the labor dispute. The board released a report Friday saying "a strike will cause significant harm to the public's health, safety and welfare."
The report cited a spike in traffic, higher risk of traffic accidents, and slower emergency response times as the potential negative consequences of a strike.
