I know teachers who have to plan accordingly with their plans via the computer. They needed to learn on their own a system where you add students to classes and teach them there. Never mind who isn't paying attention, who needs to go to the bathroom, and who isn't listening or learning. You're responsible for testing and grading. I don't envy being a teacher today. Parents have had to hire sitters or stay at home themselves to make sure kids are paying attn. Not easy for anyone, but it beats getting sick.
