Part-time janitor Anna Lopez, 50, of Houston, Texas, right, was joined by Jose Molotla, 60, a janitor from Chicago, as members of the Teamsters and other labor, community and religious representatives rallied in support of the Service Employees International Union (SEIU) Local 26 at Minneapolis City Hall on Thursday. Twin Cities-area janitors, who have been working without a contract for over a month, could walk off their jobs at anytime in the coming days and weeks, in their fight for more affordable health care.
