BART officials may impose work conditions tomorrow on unionized employees, in a move that could trigger a debilitating transit strike. According to the Chron, BART management has given unions until the end of today to reach an agreement that would slash $100 million from employee compensation. BART managers want to cut overtime and require workers to shoulder more of their health-care costs. But if unions refuse, then management says it plans to impose those conditions unilaterally. If that happens, then the unions may go on strike, effectively shutting down the transit system. BART workers have been unwilling to make significant concessions during the current recession unlike other unionized employees throughout the region.
