In the district where I work, if your class is told to open it is very difficult for staff to opt out. So far they have opened special ed classes for moderate/severe students. My co-workers and I communicated that we were very uncomfortable with the prospect of being in a classroom with our disabled preschoolers. They will not keep masks on their faces, and have no concept about social distancing or the need to keep things clean. We could only opt out if we had a documented medical reason to avoid Covid, which none of us do. The other option was to take an unpaid leave of absence and either lose our benefits or pay for them out of pocket. I am currently covering medical benefits for my family. If I stayed home, not only would I not get a paycheck but I would have to pay $1600 a month to keep our coverage. DH is just finishing a contract position and will be unemployed soon. Taking a leave is not an option for me.
I've been back working in-person for a week while most of the district is still on distance learning. It's been nerve-racking and a bit scary. We work all day in masks and plastic face shields and use lots of gloves. I do not think it's totally safe for the kids. They are allowed to play together and with the same toys since they're part of the same cohort. We try to grab and wash toys that have been in mouths, but our kids tend to drool and wipe their noses and faces everywhere. We try to be ready with tissues, but the germs still get spread around. It's pretty clear that if one child has Covid, they will all get it and take it home. It's even more scary that small kids tend to be asymptomatic. We do take their temperatures and ask parents health-related questions each morning. But we could easily miss an asymptomatic case. Personally, I would not be sending my small child to class right now, but that's just my opinion.
