The district, which has an operating budget of about $14.7 million, proposed a 6.58 percent salary cut for the current school year while the union proposed a 4.58 percent cut.
Members of the Alpine Teachers Association gave their board permission to strike after their salaries were already cut by 7.58 percent. The strike comes after 16 months of negotiations failed.
In an interview with 10News Thursday morning, Superintendent Tom Pellegrino said he's waiting for the teachers union to come back to the negotiations table.
"A strike is where the teachers are in the driver's seat," he said. "If we had the money, we would fulfill their proposal. We simply do not."
The district said it hired 122 substitute teachers to cater to the 1,700 students in Alpine.
