LANSING (AP) — The majority of educators in Michigan have safety concerns and don’t believe they’ll be able to return to in-person learning in January, according to a study from the state teachers’ union.

The survey by the Michigan Education Association found 74% of the responding educators prefer some level of virtual learning now. More than 47,000 educators responded to the survey this month. The union has about 120,000 members. Of those responding, 84% reported safety concerns over a return to full in-person learning and 68% reported that they weren’t confident that schools will be able to return to in-person instruction in January.

But 41% of educators reported that remote learning has been somewhat ineffective or not effective at all.
