LITTLE ROCK, Ark. — The Little Rock teachers union says its members won’t show up for in-person classes due to concerns about the spread of coronavirus in schools.

The Little Rock Education Association said Sunday its members are willing to teach classes virtually, but accused district administrators of not doing enough to prevent the virus’s spread. It was unclear how many teachers planned to participate in the action.

“At this juncture, LREA members believe that our schools are not safe for in-person instruction and that the risk to our students, our staff members and our community is too great,” the association said in a news release.

The superintendent of the state-controlled 21,000-student district said it was taking additional steps to ensure schools stay open for in-person instruction. Arkansas is requiring its public schools to stay open for in-person classes five days a week, though they can also offer virtual or hybrid options. Schools reopened Aug. 24.
