(BCN) -- San Francisco Mayor Daniel Lurie and state Sen. Scott Wiener on Sunday called for an additional three days of negotiating between the school district and teachers union before any looming strike may be called. United Educators of San Francisco, while negotiating a new contract with the Sa n Francisco Unified School District, said they reached agreement Saturday on one of several divisive issues, but not enough to head off a threatened strike. "Both sides made important progress yesterday, and I am incredibly appreciative of the hard work of our educators and the district," wrote Lurie on social media on Sunday afternoon. "Now, it is critical that they continue the conversation so our kids can stay in school." Lurie said that if no agreement is reached on Sunday, he is asking that both the union and district "agree to three additional days for conversations to continue--that would allow kids to stay in the classroom and the adults to keep talking." Wiener concurred with the mayor on Sunday afternoon in a statement from his office in support of teachers but calling for more time. "It's absolutely essential to make every effort to negotiate a resolution to the current dispute between the District and UESF before any strike occurs," he said. If no agreement is reached, public schools will be closed Monday, marking the first strike by the city's teachers in 47 years. "We are thrilled to have won protections in our contract tonight that will create security and stability for our immigrant students and families," said Cassondra Curiel, president of the United Educators of San Francisco, late Saturday night. The union has sought to include the district's existing policies on immigrant rights in the new contract. However, there was little movement on wages and a demand for fully paid family healthcare, the union said. On Sunday, Curiel led a news conference where she said the district had handed them their response just after 8 p.m. Saturday and that her side is working on responses to those proposals. "We know the district is aware of what we are asking for, we've said it again and again, and I'm saying it again now," said Curry. "We need to see their serious movement. We'll be on strike Monday without an agreement." Superintendent Maria Su, who took part in Saturday's talks, said she was "deeply frustrated and disheartened that we did not reach a tentative agreement." Su said the district's latest offer on Saturday included a 6% raise over two years and a health benefits allowance of $24,000 a year. The union is asking for 9% over two years and coverage of up to 75% of health care costs at Kaiser or provide teachers with $2,000 a month for their own health care expenditures. On Sunday, Curiel said the union would not accept salary increases that do not come "at the cost of concessions or takeaways" or salary increases that come with cuts to school sites. Hard caps on class sizes and the union's demands to alleviate the workload of special education teachers by hiring more and changing the way their workload is assigned were also areas of disagreement.
