Teachers at the San Francisco United School District could go on strike as early as Wednesday.
On Saturday, the United Educators of San Francisco, the teachers union, voted overwhelmingly to give union leaders the power to call a strike amid an impasse in contract talks with the district.
The two sides have been negotiating for more than a year. District officials said they remain divided over union demands for higher pay and fully-funded family health care benefits.
A neutral fact-finding committee is expected to recommend a contract offer on Wednesday. If the union rejects it, a strike could be declared then.
The district has offered the union a six percent salary increase, spread out over three years. They argue that the district has no surplus and a wage increase above the offer would force them to make budget cuts elsewhere.
