Over the weekend, bus drivers at Compass Transportation entered the Teamsters union hall in San Leandro, California and voted 75 to 0 to approve a three-year contract. It includes solid raises as well as improved schedules and benefits. The drivers joined Teamsters Local 853 in February and began negotiating the influential deal. Their victory is part of a larger movement — recently coined “Silicon Valley Rising” — in which labor unions, community groups, and churches have improved wages and conditions for the region’s service workers. The nearly 200 bus drivers employed by Compass provide shuttle services to companies such as Apple, eBay, Yahoo, Evernote, Genentech, Zynga, and Amtrak.
