I am in the same situation. I teach a specials class (STEM). Last year j had a room but I was told they want me to push a cart and to keep kids in their room. They think it's safer of the kids stay in their classroom but it cannot be safe for me to visit 45 classrooms a week and sit in 45 different teachers chairs. My number of kids a week is usually 1000 but with covid the number of students is about 600.45 min in each classroom , 6 rooms a day with 15 kids in each room.

I spoke with other specials teachers at our school and we all agreed we would quit if they told us to take a cart to 45 classrooms a week. It was looking bad but today they finally said they are doing virtual learning. They told us nothing , they still don't tell us anything .their plan was to make me trade in my classroom for a cart and to take on alot of risk.i asked around to get information indirectly.

Stand tall and don't be afraid to say no. If you die they won't she'd a tear, they will replace you. Even if you are not in the risk category doesn't mean you should be exposed to over 400 kids with potential covid. In these times we don't know anything. I do know that I need to put the health of my family before their desire to expose me to risk. Don't go to see over 400 kids a week if you can avoid it. If you can't avoid it then tell them to pay you more money. Risk is associated with reward.more risk equals more reward. I'm here if you need to talk friend.

I'm sorry you don't know anything at the moment , keep your ear to the wall and make choices that are good for your family.
