ADAMS TWP — The Mars School District and the teachers union bargaining unit have reached a tentative two-year agreement.

Neither side could divulge details of the contract because it has not yet been presented to the 200-member Mars Area Education Association.

Both sides will vote on the tentative contract Nov. 5.

Tom King, negotiator for the school district, said today the two sides negotiated for four hours on Monday night before agreeing to the terms of the tentative document.

“I am optimistic it will pass,” King said.

Rob Case, president of the MAEA, said hard work by the union during the summer and recently has resulted in the deal made Monday night.

“Right now, I think we’ve hammered out a fair deal for the teachers and the school district,” Case said.

Negotiations have been ongoing at Mars since January. Teachers agreed to a one-year extension of their old contract for the 2011-12 school year because of the financial difficulty Gov. Tom Corbett’s budget caused Mars and all districts across the state.

Mars remains in contract negotiations with its support personnel union, which includes the district’s janitors, paraprofessionals, secretaries and guidance counselors.
