San Francisco Bay Area Rapid Transit workers are threatening to go on strike at midnight after unions and management reached an impasse in their marathon contract talks.
A union leader announced Thursday that BART and union negotiators have agreed on economic, health care and pension issues, but remained apart on work rule issues.
Roxanne Sanchez, president of Service Employees International Union Local 1021, said that workers would go on strike at midnight unless BART officials agree to submit the remaining issue to arbitration.
