The strike will take place at all five schools in the district, which serves Sheridan and parts of Englewood and Littleton. The Sheridan Educators Association, which is made up of teachers, mental health providers, bus drivers and other staff, said it expects close to 100 members to participate in the strike.

The union, which voted to authorize a strike in early March, has said that district officials told staff in December they no longer have a union and refused to transmit teacher dues to the association.

District officials sent a letter to families Tuesday announcing their decision to close schools at least through Friday because of the strike.

“Over the past several days, we have worked diligently to keep our schools open and operating for students and families,” the district said in the letter. “However, due to current and anticipated staff absences, we will not have enough personnel to safely maintain normal school operations.”

Sheridan has 997 students as of the 2025-26 academic year, according to state data.

“…The district will be monitoring the situation daily,” said Polly Plancarte, an executive administrative assistant for the district in a statement. “Our priority is to be as least disruptive as possible for students and families, and our goal is to keep schools open.  However, if safety and adequate supervision become a concern, we may need to consider closing school(s).”

The union said that in December, district officials told employees they no longer have a union and refused to transmit teacher dues to the association.

Between 74 and 170 educators are expected to participate in the strike, the union said.
