LOL!! So the pandemic has caused the little bastards to turn into terrorists?
The little b______s were ALREADY terrorists, at least in NYC. Under DumblASSio, it became nearly impossible to give students detentions and especially to suspend them for disruptive behavior, assault on other students or teachers, threats of physical harm, and any one of a number of way-over-the-line behaviors. And with DumblASSio, students of "color" were singled out for special protection from any punishment, because black wannabe DumblASSio felt that they were being punished unfairly. Novel thought: What if they were actually committing the disruptions, assaults, thefts, etc. in greater numbers than white or Asian students? Because that is exactly the reality. So now they know they had the protection of their complexion to go and do anything they darn well pleased, no consequences for THEM.
After no classroom discipline from being home for months, they are not likely to want to go back into harness. They will not be able to sit and listen and take notes or do whatever the teacher wants them to do in order to have an orderly atmosphere for learning.
Many teens (and younger children) don't have the best personal hygiene or hygienic habits. I'm sure they will not wear their masks properly---I see how people in stores walk around with their masks only over their mouth, or hanging from their neck, rendering them utterly useless. I can't imagine teachers being coughed on, sneezed on, touched by students all day, in a closed environment, and not having an increased risk of catching COVID. Keep in mind that a lot of teachers are ove 60 and/or have underlying health issues such as diabetes, making them more susceptible.
I know that a couple of my former teaching colleagues who have a few years to go before retirement put in many hours preparing lessons for the long distance learning. They were not at home sitting on their duffs. They also put in many hours grading submissions of students. Long distance learning does not begin to replace in-person learning; the teacher cannot gauge from body language where the students are at in understanding. You cannot count on them raising their hand to ask a question, because they rarely do. They'd much rather sit there without a clue than reveal to their classmates that they don't understand something. Unfortunately, their subsequent grades then reflect that---they fail. But being socially "cool" is so much more important than understanding the subject being taught.
I really don't know a practical solution to this problem. But I know that a lot of the comments here condemning teachers as being lazy, on vacation, etc. are way off base and unfair. Teachers want to get back to personal teaching, but they also don't want to contract COVID or bring it home to their own families.
