KENAI, Alaska (AP) – The Kenai Peninsula Borough School District and unions representing teachers and support staff have reached a tentative agreement and averted a strike that would have started on Tuesday.

Officials announced the agreement came at 1:37 a.m. Tuesday.

The three-year agreement covers a contract period from July 1, 2018, through June 30, 2021.

Schools were scheduled to be closed on Tuesday because of the impending strike, but will start after a two-hour delay for the district’s 42 schools.

School officials said details of the contract agreement will be posted later Tuesday on the district and union’s web pages.
