The San Francisco Bay Area Rapid Transit agency's board has overwhelmingly approved a revised labor deal with two of its largest unions to finally resolve months of contentious negotiations.

The board yesterday voted 8-to-1 to approve a four-year contract to settle a dispute over paid medical leave for employees that arose in November after BART management and its two biggest unions previously reached a deal ending a second strike in October.

The new deal dropped a controversial clause granting union members up to six weeks of paid family medical leave that BART officials said was mistakenly included and would cost $44 million if one-third of the agency's workers took advantage of it.

The unions are expected to vote on the deal later this month.
