San Francisco has announced plans to mobilize its 911 dispatchers for the first time in over 15 years when world leaders flock to the city for November’s Asia-Pacific Economic Cooperation summit. But the dispatchers’ union is opposing the demand, raising concerns over chronic burnout and questioning whether city officials may force workers to log the long hours the mobilization would require for a planned event as opposed to a bona fide disaster situation.

The dispatchers’ opposition stems from a long-running conflict between the union and the city. Dispatchers want to be classified as public safety workers, a designation that would come with improved benefits similar to those enjoyed by police officers and firefighters, including retirement as young as 50 years old and a pension that pays as much as 90% of their annual salary.
