The planning being done for the next school year where we live is complete bullshit. The politicians and administrators running the planning have no idea about the realities.
They are driving these hybrid models with kids doing remote and in-person learning in alternative days/weeks with the in-person class sizes being about one third of the normal class size. To do that they would need at least twice the amount of teachers (one to teach in-person, and one to teach remotely to kids staying at home), possibly even more. Are they planning on hiring more teachers? No.
It's going to be a complete shitshow even without teachers quitting en masse.
There's this completely unrealistic sense among the people in charge that teachers will just magically make it work with no additional training, no proper support, no additional resources, nothing.
And I'm not even addressing the difficulties families, especially those that have multiple kids and/or can't work from home, will have with these proposed schedules.
