BART SCUM EXECUTIVES ATTEMPT TO PULL FAST ONE ON ITS UNION EMPLOYEES

"The Board of Directors is not in any position to cherry-pick which parts of the contract it intends to honor and which it does not," said Kate Hallward, an attorney for SEIU. "We have a complete and final agreement, and they need to honor it."
David Rosenfeld, a law school instructor at UC Berkeley and a veteran labor lawyer who works for unions, said the notion of negotiating a contract and then approving a revised version is unheard of.
"It's totally unprecedented for an employer to later come back and say, 'We need to amend this, we made a mistake,' " he said. "You can't just back out of a deal you've agreed to because you decide later you don't like it."
