The superintendent of the Central Falls schools says she will fire every teacher at the high school after they refused to accept a reform plan.
The plan was offered under a state mandate to fix the school, which has among Rhode Island's worst test scores and graduation rates.
The plan included six conditions such as adding 25 minutes to the day and providing tutoring outside school hours.
The added work didn't come with much extra pay and the teachers union refused to accept it.
Superintendent Frances Gallo blasted the union's "callous disregard" for the situation. She said the school's 74 teachers will be fired, effective next school year.
