BRUNSWICK

School administrators soon will be begin contract negotiations with its custodians, bus drivers and education technicians.

The district has three “bargaining units” with which it must reach agreement, said Superintendent Paul Perzanoski.

Teachers finalized their three-year contract renewal in April; custodians and bus drivers comprise a second unit, while “ed techs” and other “non-teaching personnel” are the third.

Educational technicians are defined by the state’s Department of Education as a classroom aides who provide instruction and review to students under supervision of a regular teacher.

The first meeting of the Personnel and Negotiations Committee is scheduled for Wednesday at 5:30 p.m., before the school board’s regular meeting at 7 p.m.

Protocol dictates that the school board has to notify the employees’ unions in writing that it would like to begin negotiations. The next step will be to outline a discussion schedule and a draft deadline for agreement.

The process was stalled for one year in 2010 when everybody — from Perzanoski to the janitorial staff — took a pay-and-benefits freeze to help resolve a district budgetary shortfall of almost $4 million.
