You could cite specific concerns that teachers may have about returning to school during the COVID-19 pandemic. Your question might read "What concerns do teachers have about ________ when returning to work in-person during the COVID-19 pandemic."
Simply adding a little more detail would clarify your question. It doesn't have to be too elaborate; maybe just, "Given the health risks and uncertainly of school and community spread of Covid 19, how do teachers feel about being forced back into school?"
I would suggest adding more detail to your question. Is this question in reference to the COVID-19 pandemic? Who (gov, school, county) is recommending that teachers go back to school? Why would teachers want to/not want to go back to school.
Try answering some of these questions and add those facts to your question!
