Striking workers at 10 San Francisco Bay Area cemeteries will end their seven-week walkout by returning to work today. A proposed three-year contract with cemetery owners was approved by a 2-1 margin by members of the Cemetery Workers and Greens' Attendants Local 265. Among other things, it restricts a practice of subcontracting; provides a 30-cent-an-hour raise for each of the next three years, and grants a raise of pension benefits. The agreement involves nine cemeteries in Colma and one in Palo Alto. More than 800 bodies have been kept in storage because of the strike.
