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.
