Undiscussed hidden costs
The problem reported seems to be silo-ed into a discussion about the impact on the school and its reaction.
As a society we all need to have resilience against this sort of attack.
Sending kids home for a couple of days appears an easy solution compared to planning for failure mentioned above, but it has massive knock-on costs, and not just financial.
My wife is a hospital doctor, and were I not able to work from home to supervise my children during such closures, her clinics would be cancelled: a further 15-20 people disappointed every day.
What about those people being paid piece-rate having to stay at home and losing income ?
Shoving our personal failure to plan as a cost onto everyone else turns out to be a cost back on us. We need to learn to work better to face these issues as a co-operative society.
I leave how one does that as "an exericse for the student".
