As usual late to the party. I am in a very different boat - my 3 kids in 12th, 10th, and 6th grade have close to a full day of school online every day. Both of my kids schools also have 'extra-curricular' online events ranging from things like - 'cooking with the morahs' to bringing in physical and mental health professionals to talk about Corona, parenting, etc. As well as shiurim.
Clearly this is by design - obviously to keep families engaged and make them feel that they're connected. Both schools have both reached out via e-mail (and the elementary school by phone) to see how we were doing and to let us know that they would help us if we became financially strapped and couldn't make payments.
This is also a huge contrast from both my friends with younger kids - who clearly don't have the zitsfleisch for this type of learning, and/or parents from kids of similar ages in more yeshivish environments (I am MO) where not everyone has Internet, and they're having conference calls and learning packets.
From being involved in some local mosdos, it seems that "Payroll" is the biggest expense for the vast majority of schools, but Payroll isn't just teachers salaries, but a whole host of other things that go with it. Healthcare, for example is HUGE. Assuming the plans offered to teachers are similar to plans offered by other employers - you have to figure that the average cost needs to be in the $20k/year range for most teachers (someone with better knowledge please correct me if I'm wrong). Yes, It's offset by single teachers, teachers with no children at home, and/or who use their spouse's insurance - but still.
Are we now going to require every Yeshiva to fire all of their teachers and make them go on cobra paid by the money they're not making? (Yes, I know that this is complicated, but that's what I see).
At the same time - I would definitely like to see some money back for Transportation, and food - this is easier to do if they're being broken out separately.
