NASHUA — The Board of Education is supporting a new contract that would offer a one-year salary increase for all school administrators.

The proposed collective bargaining agreement between the school board and the Nashua Association of School Administrators and Supervisors is being recommended by a vote of 7-1.

If approved by aldermen, the new contract would provide 52 school administrators and supervisors with a 2.5% salary increase. The one-year contract would run from July 1, 2019 to June 30, 2020.

The proposal would increase the total base pay for union members from $3,425,325 to $3,510,958, according to the contract.

The Board of Aldermen was presented with its first reading of the proposed agreement on Tuesday, which has now been assigned to the aldermanic budget review committee for further discussion.

Several aldermen are sponsoring the proposed resolution, which would require a nearly $70,000 transfer from the city’s contingency account to the school department.

Howard Coffman, member of the Board of Education, was the only school board member to vote against the contract.

“The problem I have with this contract has to do with the amount of sick days and vacation days,” said Coffman.

According to Coffman, administrators or supervisors who have been with the district for an extended period of time are eligible for 50 days off per year. He maintained that the high number of days off per employee is not sustainable for the district.

According to the contract, full calendar year members receive 20 days of annual vacation leave, which can be accrued on an ongoing monthly basis; members may accumulate and carry over up to 40 vacation days on Aug. 1 of each year.

They are also entitled to 11 or 15 sick days per fiscal year, as well as three or four paid personal days depending on whether they are full-year or school-year members.

Dan Donovan, the school district’s chief operating officer, said the union tentatively approved the contract with a unanimous vote.

“No employee shall be placed on the salary scale above their supervisor with comparable experience,” states the contract, which emphasizes the 2.5% salary raise during this school year.

The contract must still be approved by the full Board of Alderman in order for it to go into effect.
