All Kenai Peninsula public schools will be open Tuesday with a two-hour delayed start after the school district and educators unions reached a tentative agreement on a three-year contract.

“Student absences will be excused—simply call the school. Sports and after-school activities will take place on a normal Tuesday schedule,” the Kenai Peninsula Borough School District said in a statement posted online.

District educators notified administrators Friday of their intent to strike beginning Tuesday after a long disagreement over health coverage.

Educators have been working under the terms of the previous contract that expired June 30, 2018.

If approved by members of the Kenai Peninsula Education Association and the Kenai Peninsula Education Support Association, the contract would be retroactive to July 1, 2018, and run through June 30, 2021.

The statement included no further details of the tentative contract, which was agreed on at 1:37 a.m. Tuesday.
