Unions, tenants, and politicians rallied at the San Fransisco sixteenth st BART station today before marching into the offices of the developer of what opponents are calling the "Monster in the Mission," a pair of ten-story condominium towers that would be the largest market rate development in the history of the Mission District. Advocates say, if built, the project will raise the average rent and displace low and middle class residents. The Service Employees International Union (SEIU) joined anti-development organizers after developer Maximus replaced dozens of union service employees at its San Fransisco Parkmerced complex with non-benefited minimum wage workers.
