OAKLAND, Calif. (AP) — The San Francisco Bay Area Rapid Transit board has approved a tentative contract deal with two of its largest unions after stripping out a disputed provision that union officials have said they want in the deal.

The decision at a meeting on Thursday creates uncertainty about the fate of the tentative contract, which will now go to the unions  for consideration.

It stemmed from a tentative agreement reached last month that appeared to settle the  months-long labor dispute.

BART later objected to the provision giving workers six weeks of paid leave each year to care for sick family members. BART said the provision could cost $44 million over four years.

The board stripped that provision before its vote.

The unions have disputed BART's figure and said they are not inclined to renegotiate the contract.
