SAN FRANCISCO — With a strike deadline drawing closer, negotiators for San Francisco Bay Area Rapid Transit system and its two unions prepared Sunday to resume contract talks that could prevent hundreds of thousands of commuters from having to find costlier and longer ways to work.
BART spokeswoman Alicia Trost said that caucuses for each side were meeting privately Sunday morning and that a mediator would bring them together ‘‘at the appropriate time.’’
The unions have vowed to walk off the job Monday morning if no new labor agreement is reached by midnight. BART workers went on strike for nearly five days in July before Governor Jerry Brown mandated a cooling-off period that ended Friday.
On Saturday, the sides met separately for most of the day and then held an evening bargaining session.
Amalgamated Transit Union Local 1555 and Service Employees International Union local 1021 want a raise of nearly 12 percent over three years, while BART has proposed a 10 percent increase over four years.
