Another East Bay teachers union is threatening to go on strike.
The New Haven Teachers Association announced its members will strike May 20 if they can't reach a contract agreement with the New Haven Unified School District.
The union is asking for a 20 percent teacher pay raise over the next two years, plus a $1,500 retention bonus each year, but the district isn't budging.
"They're still continuing to offer us zero for anything in terms of a compensation package, which of course, is unacceptable," said New Haven Teachers Association President Joe Ku'e Angeles.
District spokesman John Mattos said they simply don't have the money to bump salaries.
"We can't afford that raise. That package as they put together would cost us over $24 million," Mattos said.
Angeles said teachers need the raise as they struggle to find affordable housing.
"We all know the cost of living is enormous. Our salaries have not kept up with that," he said.
New Haven teachers are the highest paid in Alameda County, earning an average yearly salary of $95,000. Mattos said that speaks for itself.
"We love and respect our teachers and I think how we pay them -- the top in the county -- I think that reflects that," Mattos said.
The district and union have been in contract negotiations since January 2017.
The strike would be the first in the district's history. It would impact nearly 600 teachers and 11,000 students in Union City and South Hayward.
Oakland teachers went on strike earlier this year. Contract negotiations are also happening at Mount Diablo Unified Schools.
New Haven teachers return to the bargaining table May 15th.
