I would think teachers would count as front line workers. Kids are little germ factories, you know this though. The quicker we get teachers vaccinated, the faster kids are back in school, faster parents can more easily earn a living and/or not have to pay for extra care they normally wouldn't have to.
I’m very lucky in the fact that I have free childcare and my son is killing it in virtual school. All the cases at my son’s school are staff members and there have been a ton in the last month. Most of the teachers on quarantine teach from home, but those kids in classrooms have to go somewhere and the teachers still in the school have to take them on. One grade level only has four teachers because one quit at the beginning of the year (there is a hiring freeze), they each have 12-16 kids in person, and when three of the four were quarantined, teaching from home, the one left had to supervise all the kids. If they were vaccinated, this wouldn’t be an issue.
If they hired more teachers, it also wouldn’t be an issue but even with the need, they won’t.
