OAKLAND, Calif. – The president of one of the two unions involved in the San Francisco Bay Area rapid transit strikes said Saturday she will take the final contract offer to members for a vote, but expects it will be rejected.

Antonette Bryant said she was unsure how long it would take to get the proposal printed and into the hands of the 900 workers represented by ATU 1555.

“It’s our hope we can get it to members this week,” Bryant said. But she said she expects the vote to be “a resounding no.”

Bryant used a news conference at the Pittsburg/Bay Point station Saturday to convince the public that workers’ demands are not unreasonable. Bay Area Rapid Transit riders who make 400,000 daily trips on the transportation system have become hostile on social media since their commutes were disrupted Friday morning.

The union agreed with BART management on the economic parts of the contract but the two sides came to an impasse over work rules, the union said.

BART spokesman Rick Rice said Saturday that the two sides remain in communication though they were not expected back at the bargaining table.

Messages left for negotiators from the Service Employees International Union, which also represents workers, were not immediately returned.

However, SEIU president Roxanne Sanchez said it was willing to sign off on pay, health care and pension issues, and send the work rules to an arbitrator, a proposal BART has refused. But BART officials later said they would be willing to send the entire contract to arbitration but not the work rules alone.
