ELKHART, Ind. -- A mediator expected to intervene in the contract negotiations between Elkhart Community Schools and the Elkhart Teacher's Association union.

In an email obtained by ABC57 News and confirmed by multiple sources, ETA leaders say the union and the district will not meet the state deadline to finalize a final master contract due to disagreements. Officials say a state-appointed mediator will work with both sides to reach a deal.

The email cites "benefits and protections" as the main sticking point in negotiations.

An ETA official declined to offer comment; ABC57 has not yet heard back from ECS.
