The Manchester Board of School Committee took a vote of 'no confidence' in Mayor Ted Gatsas at a meeting Monday night, according to the New Hampshire Union Leader.
The 10-2 vote comes after Gatsas vetoed a three-year contract with city teachers.
School board members also asked aldermen to reconsider their vote on the agreement, and urged Gatsas, who chairs the school board, to recuse himself from a reconsideration vote.
Aldermen had approved the contract by a 7-3 vote.
More than 100 teachers wearing red gathered outside City Hall before the meeting to rally in support of the contract.
Gatsas said the city couldn't afford the contract, citing numbers from the city's finance director that projects deficits of more than $700,000 in fiscal years 2017 and 2018.
Monday night, Gatsas called for a special meeting to review those numbers.
Incoming Manchester Education Association President Sue Ellen Hannan told the Union Leader the veto was a "complete disappointment."
She said the MEA's executive board would meet Tuesday to explore next steps.
Superintendent Debra Livingston said she would not "take or negotiate" a raise until the city's teachers have a new contract.
