Bon courage.
FWIW, I think the sniping at the teaching profession that's been going on in certain sectors of the media is a disgrace. It's not unreasonable for teachers to want to be sure that it is safe to go back, for the kids, for the staff and for the parents.
If nothing else, one might hope that the experience of home schooling has enabled some to have a greater appreciation of the job that teachers do.
It must be nice to have the luxury of being able to pick and choose if you feel like going into work or not while the tax payer is picking up 100% of your salary for months on end - they get part of July and all August off as it is.
Is there 100% guarantee of safety? - No, but millions of far less privileged workers are having to get on with it.
The public appreciate teachers and will cut them a lot of slack until they start taking the mickey a bit too much.
You know it makes sense!
